Sustainability pushes a lot of our hot buttons—it’s a political issue, an economic concern, and a social conversation. Some people even see it as a moral matter. Sometimes it’s on the back burner, but then it blazes back into the headlines. Sustainability is, arguably, an industry unto itself, since the economic impact on companies trying to adhere to government guidelines or react to consumer preferences can be in the billions of dollars across a wide range of markets. Sustainability demands are hitting a variety of industries, not just food and beverage. For example, the move from the internal combustion engine to the electric vehicle can be called a “sustainability” issue.

The Eight Elements of Sustainability
1. Consumer preferences
2. Climate change
3. Food insecurity
4. Food waste
5. New foods
6. Packaging
7. Regenerative agriculture
8. Transportation and regulatory restrictions
In light of the many disruptors in the food and beverage industry and most recently, due to the impact of the COVID-19 pandemic, sustainability is now front-page news. This article will discuss eight reasons why sustainability is now one of the defining issues in food and beverage manufacturing. Future articles in this series will examine each issue in more detail.

Consumer Preferences

The green consumer wants brands to embrace purpose and sustainability, and they want their purchases to contribute to the greater good, or at least, do no harm. The demand started among millennials and Gen Zers, but with the influence of social media, it’s expanded to all demographics.

The industry has been forced to introduce healthier products, with more ethically-sourced ingredients and more transparent supply chains. Younger consumers, especially, often trace a brand’s sustainability record with QR codes or smart labels. They want to know from where their food originates.

These consumer actions and attitudes are now influencing the development of new food items and packaging designs as manufacturers realize consumers are taking notice.

Climate Change

Warming is causing the earth’s poles, permafrost and glaciers to melt and the oceans to rise. Average sea levels have swelled more than eight inches since 1880, with about three of those inches gained in the last 25 years. Here’s the impact on sustainability—when sea levels rise and warm, flooding can occur, causing coastal seawater contamination and erosion of valuable farmland. Higher air temperatures may also rule out the cultivation of some valuable crops (gasp, chocolate!).

Hotter temperatures can also cause insect body temperatures to rise; they need to eat more to survive and may live through the winter instead of dying off. A larger, more active insect population could threaten crops. And changes to water, soil and temperature could affect the complex ecosystems of the world’s farms, causing plant stress and increasing susceptibility to disease. The food manufacturing and farming industries are starting to investigate new ways of growing food in environments that can protect crops from these changes.

Food Insecurity

Food demand is expected to increase anywhere from 59% to 98% by 2050. Populations are growing and due to rising incomes, demand is ramping up for meat and other high-grade proteins. At the same time, climate change is putting pressure on natural and human resources, making it challenging to produce enough food to meet the world’s needs.

The world agrees that governments, manufacturers and consumers have a social responsibility for to do their part to combat world hunger. Consumers are becoming more aware of food security and the threat that climate change poses. People are attempting to eat sustainably with meals designed to have a lower environmental impact, and incorporating an awareness of plate portions and food waste.

World health organizations are also stepping up. The United Nations World Food Programme (WFP) is the food-assistance branch of the United Nations and the world’s largest humanitarian organization, addressing hunger and promoting food security. The WFP works to help lift people out of hunger who cannot produce or obtain enough food for themselves, providing food assistance to an average of 91.4 million people in 83 countries each year. Food brands worldwide are offering support through donation programs, new product development to provide more nutrition with less and new sources of food.

Food Waste

Around one-third of the total food the world produces—around 1.3 billion tons—is wasted. It’s more than just the direct loss; food waste contributes heavily to climate change, making up around eight percent of total global greenhouse gas emissions. Food manufacturers are making significant efforts to reduce their food waste footprint. Is it possible to anticipate and plan for potential glitches in frozen food processing? Sustainable brands make contingency plans in advance so that food can be stored safely while a broken line is fixed, rather than let it go to waste. What should be done with raw materials left over after processing? Perhaps there are other creative uses for it—vegetable waste, for example, has been used for fertilizer.

Human behavior is a main contributor to climate change and the motivator for new sustainable practices. Over time, community attitudes can change habits, like encouraging commitments to composting or recycling. In certain communities, grocery stores and restaurants contribute leftover food to charities. Portion control at restaurants and in the home can make us healthier and also help to reduce food waste.

New Foods

In response to changing food preferences and the demand by consumers for healthier options, food and beverage companies have the opportunity to develop new foods and build a reputation for sustainability.

Brands have been working on protein alternatives, but one can argue that plant-based protein went mainstream when news broke in 2019 that both McDonald’s and Burger King were testing plant-based burgers. And with veganism and vegetarianism growing, tofu, seeds, nuts and beans are also showing up in kitchens more frequently, as are products made from them.

Did it surprise you the first time you heard about cauliflower pizza crust? Food manufacturers have been actively introducing new products like this, substituting vegetables for carbohydrate-rich grains. Product manufacturers have brought us new product options like zoodles made from squash as a substitute for spaghetti. Utilizing products differently is a sustainable tactic. In addition, it opens up new markets, expands the value chain and increases business opportunities for food and beverage manufacturers.

Packaging

Sustainability also involves sustainable or “eco-friendly” packaging. Packaging with a reduced environmental impact is becoming a consumer priority.

What is sustainable packaging? It can mean packaging made with 100% recycled or raw materials, packaging with a minimized carbon footprint due to a streamlined production process or supply chain, or packaging that is recycled or reused. There is also biodegradable packaging like containers made from cornstarch being used for takeout meals.

To help fight food waste, intelligent packaging for food can use indicators or sensors to monitor factors outside the packaging like temperature and humidity, or internal factors like freshness. Smart labels can tell an even more complete story about what sustainable practices have been used in packaging manufacturing or along the supply chain via a QR code or webpage.

Optimizing product density for transport is another sustainability technique. Minimizing packaging can reduce shipping weight and packaging waste to minimize an organization’s carbon footprint. An added benefit is that manufacturers can deliver more in less time thus improving customer service and keeping the supply chain moving.

Regenerative Agriculture

Sustainability may call for practices that maintain soil health, but regenerative agriculture goes further; it looks to reverse climate change. Regenerative techniques promote the need to restore soil health, rebalance water and carbon cycles, create new topsoil and grow food in a regenerative way—so nature has the boost it needs to sustain improvement. If the quantity of carbon in farm soils increases 0.4% each year, says the European “4 Per 1000” initiative, it could offset the 4.3 billion tons of CO2 emissions that humans pump into the atmosphere annually.

The regenerative food system market has drawn investors, wedding the benefits to both water and soil to economic incentives. Unhealthy soil requires more water to produce the same amount of food. Healthy soil resulting from regenerative agricultural practices holds more water and therefore requires less water to be added. Underground and hydroponic versions of regenerative agriculture are also emerging.

Transportation and Regulatory Restrictions

Sustainability is also dependent on transportation and the supply chain. Governments are evaluating current practices and implementing changes that can positively affect climate change.

The food and beverage industry is actively embracing other changes that affect sustainability. Electric trucks fit well with their distribution hub model, with clean, quiet, short run deliveries. Fuel usage during transportation is being considered from every angle. Local and regional food systems, where farmers and processors sell and distribute their food to consumers within a given area, use less fossil fuel for transportation because the distance from farm to consumer is shorter, and therefore reduce CO2 emissions.

These eight areas are the defining issues facing food and beverage manufacturers today in sustainability. Sustainability impacts all of us, everywhere, and food and beverage manufacturing is right in the middle of it. What this means to the manufacturing world is that they must prepare their processes, systems, infrastructure and mindset to evolve their business in tune to the evolving issue of sustainability.

As COVID-19 Stresses Food Suppliers, Technology Steps In

By Maria Fontanazza

Mikael Bengtsson, Infor

The theme of better traceability and more transparency is a theme that will only grow stronger in the food industry. Just last week we heard FDA Deputy Commissioner for Food Policy and Response Frank Yiannas talk about the agency’s recently proposed FSMA rule on food traceability during the 2020 Food Safety Consortium Virtual Conference Series. In a recent Q&A with Food Safety Tech, Mikael Bengtsson, industry & solution strategy director for food & beverage at Infor, explains yet another role that technology can play in helping companies maintain agility during changes that affect the supply chain such as the coronavirus pandemic.

Food Safety Tech: How can food suppliers mitigate the risks of foodborne illness outbreaks under the stress of the COVID-19 pandemic and with limited resources?

Mikael Bengtsson: Food safety must always be a top priority for any food and beverage company. The risks associated with contamination can have a severe impact for public health, brand and company reputation. Safety routines are therefore always of the highest priority. In today’s situation with COVID-19, the stress on safety is further increased. Now, it’s not only about keeping products safe but also keeping employees healthy. One progression and resource that all food suppliers must follow is the FDA [FSMA rules], which require suppliers to be diligent and document their compliance. Especially now, while suppliers are faced with limited resources and additional stress during the pandemic, they must rely on the basics—ensuring masks are worn in and out of the workplace, washing hands for at least 20 seconds prior to touching any food, and remaining six feet apart from co-workers. When it comes to a crisis like COVID, take solace in knowing suppliers can rely on the basics—even when conditions are strained.

This year we have seen many companies having to adapt and change quickly. Demand has shifted between products, ingredients have been in shortage and many employees have had to work from home. Some were better prepared than others in adapting to the new situation. Technology plays a big role when it comes to agility. Regarding food safety, there are many proactive measures to be taken. The industry leaders establish transparency in their supply chain both upstream and downstream, use big data analysis to identify inefficiencies, as well as couple IoT with asset management systems to foresee issues before they happen.

FST: How can technology help suppliers meet the growing consumer demand for transparency in an end-to-end supply chain and improve consumer trust?

Mikael Bengtsson, Infor
Mikael Bengtsson, industry & solution strategy director for food & beverage at Infor

Bengtsson: Communication with consumers is changing. It is not only about marketing products, but also to educate and interact with consumers. This requires a different approach. Of course, consumers are loyal to brands, but are also tempted to try something new when grocery shopping. After a new study is published or a new story is written, consumers are likely to shift their shopping preferences.

It is therefore important to build a closer connection with consumers. Companies who have full supply chain visibility, transparency and traceability have detailed stories to tell their consumers. One way they can build these stories is by including QR codes on their packages. The consumer can then easily scan the code and be brought to a website that shows more product details—e.g. who was the farmer, how were the animals cared for and what sustainability efforts were involved. These are all important aspects to build consumer trust. According to researchers at MIT Sloan School of Management, investing in supply chain visibility is the optimal way to gain consumer trust, and can lead to increased sales.

FST: What technologies should suppliers leverage to better collaborate with trading partners and ensure consistent food safety procedures?

Bengtsson: When a food safety problem arises, batches, lots, and shipments need to be identified within minutes. Manufacturers must be able to trace all aspects of products throughout the entire supply chain—with complete visibility at the ingredient level—from farm to table, and everything in-between. An efficient and transparent food supply chain requires extensive collaboration and coordination between stakeholders. New technologies can extend both amount of collaboration possibilities and the impact of those collaborations. In order to maintain a transparent, efficient food supply chain, companies need to invest in modern cloud-based ERP and supply chain systems that incorporate the increased visibility of the Internet of Things (IoT) with data sharing, supplier and customer portals, and direct links between systems—all aimed at facilitating joint awareness and coordinated decision-making. Modern technologies that enable transparency will also have the added benefits of meeting consumer demand for product information, identifying and responding to food safety issues, reducing food waste, and supporting sustainability claims.

COVID-19 Led Many Dairy Farmers to Dump Milk

By Megan Ray Nichols

Megan Nichols

Much of the news coverage surrounding the COVID-19 pandemic mentions infection numbers and fatalities. Those are undoubtedly important for showing parts of the overall impact. However, it’s easy to overlook the ramifications felt by some professionals. One recent example concerns the instances of dairy farmers dumping milk.

Numerous Factors Contributing to the Problem

The pandemic drastically and dramatically disrupted life. Many of the associated changes affected milk producers, but perhaps not in the ways people expect. As schools closed and restaurants operated on delivery or a takeaway-only basis, the demand for milk typically consumed in the food and educational sector went down.

Consider, too, that the pandemic forced the closure of enterprises that did not necessarily serve large quantities of milk every day but still likely placed ongoing orders with suppliers. For example, a daycare center might give toddlers boxes of dairy beverages each day during snack time. Coffee shops often add milk to their lattes or set out bottles for people who want to put some in their coffee.

When coronavirus cases emerged in the United States, many people panicked and flocked to grocery stores for essentials. Milk is often one of the staples people buy before winter storms hit, and they wanted it to prepare for the pandemic, too. One Target store in New Jersey sold out of its entire stock of milk in only five minutes. Stores responded by imposing per-person limits on the product.

If the demand exists, what caused the milk surplus? Part of it boils down to a lack of space at milk processing plants. A related issue is that processors typically serve particular markets. One might cater to retail buyers while another primarily addresses needs in the food service sector. They lack the infrastructure to pivot and begin accepting milk orders from a new type of customer, particularly if the milk-based product is substantially different, like sour cream versus ice cream.

A First-Time Phenomenon

Farmers discarding milk is not unheard of, but it’s not something many producers do regularly. Andrew Griffith, a professor at the University of Tennessee, said that some farmers had to do it recently for the first time in careers spanning decades. He explained, “It’s not that [dumping] hasn’t occurred from farm to farm.” Adverse weather conditions can delay pickups, and unexpected supply spoilages might lead to too much milk.

“But we’re talking about a level of dumping that is not common at all. There [are] a lot of farmers that are experiencing dumping milk for the first time in their 30- or 40-year careers,” Griffith said in an article published on The Counter.

The highly perishable nature of milk poses another problem contributing to the milk surplus. That aspect hit dairy harder than some other types of agricultural goods. People could put grain into silos, but storage is more complicated for dairy products.

Any exposure to higher-than-recommended temperatures causes spoilage. The subsequent risk to consumers means farmers must throw it away. Cold storage facilities are essential for the dairy industry. Statistics from 2018 indicated an average of 10.67 cents per kilowatt-hour for energy consumption at commercial facilities. However, cold storage facilities operate 24/7, so their energy needs are often higher than those of other commercial buildings.

The delicate nature of the product is another unfortunate aspect that may lead to dumping milk. If a processor has no room to accept the raw goods, there’s nowhere for them to go. In April The Wall Street Journal reported that in one week, producers threw out as much as 7% of the milk in the United States from that period. The same story highlighted how a specialty cheese factory saw sales of its chèvre and ricotta drop by 95% in one day.

Coping With Dairy Industry Fluctuations

The coronavirus is only one of the challenges likely to impact the dairy industry in the coming months and years. A Statista chart profiles the progressive decline of milk consumption in the United States. The average amount of milk per person in 1975 totaled 247 pounds. It plunged to 149 pounds by 2017.

There’s also the issue of people showing a growing preference for plant-based milk alternatives. One industry analysis tracked sales of traditional and oat milk during mid-March. Purchases for the first category rose by 32%, while oat milk sales soared by 476%. A potential reason for that huge increase in the latter category is that supermarkets sell shelf-stable milk alternatives. Those often stay in date for months when unopened.

People can get them in the refrigerated section, too, but they may have preferred not to as they cut down their shopping trips due to COVID-19. Consumers also noticed the increasing number of milk-like beverages made from hemp, hazelnuts and other options. If a person tries one and doesn’t like it, they may try a different option.

Despite those challenges, some dairy farmers anticipated favorable trends—at least before the coronavirus hit. Producers get paid per 100 pounds of milk. Katie Dotterer-Pyle, owner of Cow Comfort Inn Dairy, said 2013 was a particularly good year for the rates. Back then, farmers received about $30 for every 100 pounds, although the price has stayed at approximately $17 per 100 over the past two years.

When Might the Milk Surplus Ease?

This coverage emphasizes the lack of a quick fix for the dairy industry strain. As restaurants reopen, that change should help address the problem, but it won’t solve it entirely. Some enterprises refocused their efforts to better meet current demands. One Dallas-based plant that handles dairy products more than halved its output of cardboard milk cartons and increased production of whole and 2% milk for the retail sector. It is now back to normal manufacturing runs.

As mentioned earlier, though, many processors can’t make such changes. Dumping milk becomes a heart-wrenching practice for hard-working producers. Many tried to compensate by selling their least-profitable cows for slaughter or making feeding changes to reduce the animals’ production. Some private entities committed to purchasing milk from farms and getting it to food banks. Other analysts say the government should step in to help.

People in the farming community support each other with tips and reassurance, but most know they could be in for a long struggle. As supply chains recovered from the initial shock of COVID-19, most people stopped panic buying, and stores no longer set product limits. Things are moving in the right direction, but the impacts remain present.

A Complicated Issue

Many state leaders have let businesses reopen, and others are following. Any step toward a new kind of normal is a positive one that should gradually help the dairy sector. However, much of what the future holds remains unknown, mainly since this is a new type of coronavirus, and scientists still have plenty to learn about mitigating it.

Since the early 20th century, food safety has been a paramount concern for consumers in the United States. Upton Sinclair’s The Jungle, which painted a bleak, brutal, and downright disgusting picture of turn-of-the-century food processing facilities led to the creation of some of the country’s first food safety laws. Today, federal agencies and statutes make up a comprehensive food safety system to ensure that the growth, distribution and consumption of foods are safe from start to finish.

While food safety has significantly improved in the century since Sinclair’s time, stories of major outbreaks of foodborne illnesses continue to pop up across the country. Over the past few years, a significant number of outbreaks as a result of pathogens have made the headlines. To mitigate the threat of public health crises and ensure food production and distribution is safe and secure, companies must rely on modern technology to trace the movement of food across the entire supply chain.

How Technology Is Changing the Food Industry

Technology is a powerful, innovative force that has changed the way even well established companies must do business in order to stay relevant. From easier access to nutritional information to digital solutions that make food manufacturing and distribution more efficient, greater consumer awareness driven by technology empowers consumers to make decisions that can greatly affect the food industry’s bottom line.

Technology-driven accountability is playing one outsized role in allowing consumers to make better choices about the foods they consume and purchase. Social media and smartphone apps connect consumers to a wealth of resources concerning the harmful effects of certain ingredients in their food, the source of products, and how particular items are made and produced. In 2015, for example, The Campbell Soup Company removed 13 ingredients from its traditional soup recipes as a result of a greater public demand to understand food sources. Neither food giants nor small producers should expect to remain immune from greater public scrutiny over food health and safety.

Nutritional research is also helping change the conversation around food, granting nutritionists and consumers alike greater access to food-related data. Through easily accessible scholarly journals, apps that provide real-time nutrition information, and meal tracking apps that help users log and understand what they’re eating, consumers can gain a better understanding of nutrition to make more informed choices about their daily food intake. Researchers can also use food-tracking apps to make discoveries about consumer behavior and foods that are eaten.

Technology is also being used to tackle food waste, one of the most pervasive problems facing the food industry. One-third of the total amount of food produced globally, amounting to nearly $1.2 trillion, goes to waste every year. Solving this pervasive crisis has become an industry imperative that is being tackled through a variety of innovative technologies to improve shelf-life, dynamically adjust pricing based on sell-by dates, and allow restaurants to automatically monitor their daily waste.

In the food manufacturing sector, digitally-connected supply chain systems are providing greater visibility into the production of foods and beverages. Supplier management technology delivers data that can be used to optimize processes and improve quality in real-time, making it easy to adjust to consumer demands, respond to logistics challenges, and boost government compliance. The enhanced operational benefits offered through improved supply chain visibility allows manufacturers to produce products faster, safer, and with greater transparency.

Online ordering has also ushered in a new era of food industry behavior. The growing assortment of online ordering apps has just given the consumer more control over quickly ordering their next meal. The trend in online ordering has also allowed restaurants to experiment with new business models like virtual kitchens that offer menus that are only available online.

IoT: The Future of Food Safety

From the farm to the carryout bag, the impact of technology on the greater food industry is already evident in daily practice. Through enhanced access to data, food producers can run an efficient supply chain that reduces waste, boosts productivity, and meets consumer demand in real-time. Using a variety of online resources, consumers are empowered to quickly make well-informed food purchases that are healthier, more convenient and more sustainable than ever before.

The Internet-of-Things (IoT) adds a layer of technology to the food manufacturing process to ensure greater food safety. A broad series of networked sensors, monitors, and other Internet-connected devices, IoT technology can oversee the entire food manufacturing and distribution process from the warehouse to the point of sale. Boosting transparency across the board, intelligent sensors and cameras can transform any food manufacturing operation into a highly visible, data-backed process that allows for better decision-making and improved real-time knowledge.

While IoT technology is a powerful tool that can improve the efficiency of restaurants and provide enhanced customer experiences, some of its greatest potential lies in its ability to safely monitor food preparation and production. Live data from IoT devices makes it possible to closely monitor food safety data points, allowing manufacturers and restaurants to reduce the risks of foodborne illness outbreaks through enhanced data collection and automated reporting.

Domino’s Pizza, for instance, embraced IoT technology to enhance management processes and monitor the food safety of its products. In the past, restaurants have relied on workers to record food temperatures, a practice that was occasionally overlooked and could lead to issues with health inspectors. Using IoT devices for real-time temperature monitoring, Domino’s automatically records and displays temperature levels of a store’s production, refrigeration, and exhaust systems, allowing employees to view conditions from a live dashboard.

In addition to boosting food safety, the comprehensive monitoring offered by IoT technology can help food companies reduce waste, keep more effective records, and analyze more data for improved operations.

IoT isn’t just a safe solution for improving food safety: It’s a smart solution.

Blockchain: The Future of Food Traceability

The ubiquity of QR codes has made it easy for consumers to quickly gain access to information by scanning an image with their smartphone. From accessing product manuals to downloading songs, QR codes make it simple to provide detailed and relevant content to users in a timely manner.

Blockchain enhances the safety of the business of food production itself.

Blockchain technology provides a powerful opportunity to provide consumers with similar information about food safety. Able to instantaneously trace the lifecycle of food products, blockchain can report a food’s every point of contact throughout its journey from farm to table. By scanning a QR code, for instance, users can quickly access relevant information about a food product’s source, such as an animal’s health, and welfare. Shoppers at Carrefour, Europe’s largest retailer, area already using blockchain traceability to track the stage of production of free-range chickens across France.

Walmart piloted a blockchain implementation by tracing a package of sliced mangoes across every destination until it hit store shelves, from its origin at a farm in Mexico to intermittent stops at a hot-water treatment plant, U.S processing plant, and cold storage facility. Real-time product tracing can be conducted in just two seconds, enabling Walmart and other vendors to provide consumers with access to food safety information that could easily be updated should an outbreak or contamination occur.

Blockchain’s inherent transparency not only makes it possible to identify the safety of food production; it also enhances the safety of the business of food production itself. Because blockchain is based upon an immutable, anonymous ledger, record keeping and accounting can be made more secure and less prone to human error. Payments to farmers and other food suppliers can also become more transparent and equitable.

The High Tech Future of Food

Unlike the days of Sinclair’s The Jungle, food transparency is the name of today’s game. As consumers continue to demand greater access to better food on-demand, food producers must continue to find innovative ways of providing safe, healthy, and ethical solutions.

IoT devices and blockchain present food manufacturers with powerful technological solutions to solve complex problems. Brands choosing to rely on these innovations, such as Domino’s and Walmart, are helping ensure that food is produced, prepared and distributed with a foremost emphasis on health and safety. As these technologies continue to become more intelligent, well-connected, and embraced by leading food producers, consumers should rest assured that they’ll always be able to know exactly what they’re eating, where it’s from, and whether it’s safe.

How Technology Simplifies Food Safety Operations

To get to the restaurant table, food must travel great lengths to preserve that farm fresh quality and in many cases, IoT-enabled sensors are being used to do this. This is especially important as the World Health Organization estimates that one in 10 people fall ill every year from eating contaminated food.

When we think of our favorite dish, we often associate it with delicious flavors, pleasant scents and even memories of a night out with friends. What we likely don’t consider is technology, something that’s critical in ensuring the meal on our plate is safe to consume. Technology plays an essential role in guaranteeing that restaurants are serving fresh food to customers. From identifying operational deficiencies to protecting the overall brand of an organization, there are certain measures restaurants are taking—whether local or country-wide chains—to ensure food quality remains a top priority.

Restaurants are perhaps held to an even higher standard than your local supermarket when it comes to the quality of food on the table. Therefore, it’s imperative that perishables are cared for properly throughout the entirety of the food supply chain and that starts well before the food ever enters the restaurant’s front door. With long-range, low-power wireless IoT technology, farmers can get insights into a number of variables that may impact the growth of their crops. Armed with that knowledge, they can make real-time decisions to optimize crop growth and ultimately produce a greater yield. For example, farmers today can set up a series of sensors throughout their farm to measure real-time soil conditions, including humidity and pH levels. If they notice an especially high pH, for example, they can immediately remedy the situation and provide the crop with the proper nutrients or conditions it needs to grow.

For food safely to arrive at restaurants, it must be kept in a controlled environment during its journey from the farm or warehouse, and carefully monitored during that time. The temperature of refrigerated shipping units or storage facilities is an incredibly important factor, as bacteria growth can increase even by simply opening the refrigerator door or with a slight temperature shift, and employees are often tasked with managing this. With large facilities comes increased labor for employees, which can lead to inefficient temperature monitoring. To eliminate food waste and contamination, IoT sensors deployed throughout facilities can eliminate human error, and deliver more consistent monitoring, via real-time updates when temperatures enter unsafe territories.

Numerous international food handling and food safety laws have been implemented to reduce the risk of foodborne illness resulting from bacterial growth. A major component of most “farm-to-fork” regulations is the ability to track, report and maintain appropriate temperature conditions inside refrigeration and freezer units throughout the entire cold chain—including when the food finally makes it the restaurant.

This is a universal priority for restaurants around the world, including Hattie B’s Hot Chicken, a southern-style food chain, which started in Nashville and now has locations nationwide. To successfully do this, the restaurant turned to technology. They used a supplier of wireless connectivity solutions with integrated long range, low power technology for temperature monitoring sensors. The sensors, which are capable of penetrating stainless steel doors and concrete walls, can monitor temperatures in refrigerators and freezers. This is essential, as the technology eliminates possible human error in manually checking temps and other food safety procedures. In instances where refrigerator temperatures shift out of range, the technology remotely notifies restaurant managers in real-time, allowing them to act quickly, ensuring their perishables remain fresh and safe for customers at all times.

Food waste in restaurants is closely tied to food safety. In the United States alone, food waste is estimated to be between 30–40% of the food supply, according to the USDA. In the restaurant industry in particular, human error is one of the most notable reasons for food waste. To eliminate the human error when handling food and monitoring storage, an IoT solution provider for the industrial, smart city and smart energy segments, integrated long-range low power technology into smart refrigeration solutions for restaurant applications. This IoT solution is designed for humidity and temperature monitoring, delivering real-time updates to managers to ensure the shelf life of food is maximized and it remains safe to consume, ultimately leading to a decrease in food waste.

From farm to table, technology plays an essential role in ensuring restaurants are delivering the highest quality of fresh, safe food. It allows organizations to identify operational deficiencies and reduce overall food safety risk, which is imperative when maintaining a strong business in a competitive industry.

Solving Food Safety Challenges in Today’s eCommerce Driven World

By Greg Balestrieri

Think about this number for a second: Consumers spent more than $19 billion on online grocery in 2019. While this is still a small segment of the overall $800 billion U.S. grocery market, more consumers than ever before are turning to eCommerce for the fulfillment and delivery of perishable goods, positioning the grocery delivery market to grow dramatically, especially as companies like Amazon continue to innovate in this area.

Adding to this, a recent survey found that 68% of consumers feel the freshness of perishable items is the number one quality they look for in online grocery retail. This is where things become complicated, as shipping perishables introduces an entirely new set of quality challenges for eCommerce brands. This is hindering the market from reaching its full potential until the biggest problem is solved: Ensuring food safety and freshness in every order.

This is a double-edged sword for retailers, grocers and CPGs: Interest in their service is taking off, but it takes just one package of spoiled meat or wilted vegetables to potentially lose a customer to a competitor—or even worse, get someone sick.

Today, spoilage and food safety issues are primarily driven by breakdowns in the cold chain, and it only takes one mishap to affect the quality of food throughout the rest of the delivery lifecycle. To achieve optimal freshness and keep customers happy, grocers, retailers and their trusted partners need to focus on three primary food freshness factors: Temperature, storage and packaging.

Controlling each of these issues starts at the warehouse.

Freshness Starts at the Warehouse

For most parcels, such as clothing, books and other commonly ordered goods, temperature control is rarely an issue. However, facilities that store perishable foods have a constant component to manage—temperature fluctuation.

According to the NRDC, cooling and refrigeration inconsistency is one of the biggest contributors to food spoilage and waste. This is because every food item has a definable maximum shelf life, and storing them at less than optimal or constantly changing temperatures can exacerbate and drastically shorten its timeline.

Mistakes with heightened temperatures on items like meat and poultry can also lead to bacteria growth and foodborne illnesses. In fact, the CDC estimates that 48 million people get sick, 128,000 are hospitalized and 3,000 die from foodborne diseases each year in the United States, putting a spotlight on how seriously food safety issues need to be taken.

The Need for Proper Rotation Processes

First expiration, first out (FEFO) is a motto all organizations should live by when stocking inventory. In addition, it is a critical process when working to avoid the food spoilage crisis. It may come as a surprise, but not all distribution centers have this type of rotation system in place. This means organizations could send spoiled food to consumers because an item was pushed to the back of a refrigerator during the re-stocking process and unknowingly shipped passed its expiration date. Not only does this create massive amounts of food waste, tarnish a brand and eat into a company’s profits by replacing low margin products, but consuming a spoiled food item can also be detrimental to one’s health.

While it helps to keep these types of costly errors in mind, as warehouse operations grow, there’s no possible way to manually scale this system.

Luckily, breakthroughs in cold chain technology have produced automated solutions that help organizations track everything from expiration dates to potential recalls. These types of technology support the entire cold chain lifecycle and ensure that warehouses and their grocery partners have the visibility they need to ensure freshness from fulfillment to the customer’s doorstep.

However, when the product is ready to leave the warehouse, it’s arguably about to enter the hardest portion of the cold chain lifecycle: Delivery.

Key Considerations for Packaging

For fragile items, packaging is all about keeping the item protected from drops and damage, but for food the focus should be on keeping the item fresh and at optimum temperatures throughout the duration of transit.

Given many grocers outsource delivery, they have little interest in whether food spoils, mainly because they are unaware of the package contents and are more focused on getting the item to the right location fast and effectively.

Yet there are many obstacles that need to be addressed during the last leg of delivery. What is the temperature in the delivery vehicle? If no one is home or at the office, will the package spoil outside in the heat?

For perishables, it is imperative that spoilage rates, delays in shipping schedules and unattended delivery scenarios are important factors in determining the amount of cold pack and protective stuffing that goes into the package. If these factors are not considered, customers could return to spoiled, melted or even crushed perishables.

Getting Food Fast and Fresh

Today, grocers and retailers are bullish on building out omnichannel food initiatives. However, balancing brick and mortar locations while developing profitable and efficient online delivery systems is often more than one organization can take on. While there are trusted partners designed to support eCommerce fulfillment and delivery, few are purpose-built to handle perishable foods.

Either way, in order to see wide-scale adoption of online grocery initiatives, grocers, retailers and ecosystem partners need to start prioritizing the key temperature, storage and packaging considerations and challenges associated shipping perishable foods. Acknowledging these challenges and implementing solutions for them will not only keep your products and deliveries fresh, but they will also keep customers coming back for more.

According to the Food and Agriculture Organization of the United Nations, it is estimated that nearly one third of the food produced (about 1.3 billion tons) globally is not consumed. To help tackle this billion-dollar problem, an innovative solution is being deployed to detect one of the key factors driving food waste: Spoilage due to fluctuations in temperature.

To get to the dinner table, food must travel great lengths to preserve that farm fresh quality. Refrigerated shipping units and storage facilities are essential to reducing bacteria growth and by using an automated smart-refrigeration solution, a food-safe environment can be maintained throughout the journey with little supervision. Traditional food temperature monitoring is reliant on staff to periodically check temperature levels and make adjustments as necessary. This process is not scalable, meaning that with a larger facility or an increased number of food displays, it becomes increasingly labor intensive and inefficient. If employees are preoccupied, periodic check-ins may be delayed or missed entirely, leading to gaps where temperature fluctuations are not addressed, opening the door for increased bacteria growth and food waste.

To solve this issue, Internet of Things (IoT) sensors can be deployed in shipping vehicles, displays, refrigerators, and storerooms to provide accurate and consistent monitoring of temperature data. When a temperature fluctuation occurs, the sensors will send a signal to a low power, wide area network (LPWAN) gateway application. The information is then relayed to a network server, where it is routed to application servers or Cloud IoT services. The data is then processed and sent to the end user through a desktop or smartphone application. What’s more, in the event of a power outage, these long range, low power wireless enabled IoT devices are battery powered and consume minimal energy, allowing for consistent off-grid temperature tracking.

These connected devices can be found globally in a variety of use cases ranging from quick service restaurants to full service grocery stores, with an end goal of ensuring appropriate temperature levels for food. To support connectivity for these devices, an open network protocol is used to ensure the devices can be scalable and globally deployed. Two recent use cases where the long range, low power wireless devices and LoRaWAN protocol were used to actively monitor temperature fluctuations are Axino Solutions (Axino) and ComplianceMate.

Axino recently integrated LoRa devices and LoRaWAN protocol into its line of smart refrigeration solutions with the goal of combatting food waste. The solution combines sensor technology with automated data communication providing a substantial increase in measurement quantity and quality. Additionally, stores found a significant reduction in metering and operating costs after sensor deployment. This smart refrigeration solution has been globally deployed and is currently used by Switzerland’s largest supermarket chain, Migos. Axino’s sensors can be quickly installed, utilizing a magnet to attach to a refrigerator’s infrastructure. The sensors monitor temperature in real time, are accurate to one degree Celsius and can be pre-programmed to adjust refrigerator temperatures to ensure that food is stored in a safe environment. By having access to real time data and automatic temperature adjustment, supermarkets were able to eliminate human error, prolong shelf life and pass energy savings off to the customers.

The challenge for any wirelessly connected device is the presence of physical barriers that will block signals. Steel doors, concrete and insulation are some of the key considerations when developing a smart solution, especially in restaurants using large freezers. ComplianceMate partnered with Laird Connectivity and found that devices on a LoRaWAN-based network produces a more reliable signal than its Bluetooth counterpart. This IoT solution has been deployed in some of your favorite restaurant chains such as Shake Shack, Five Guys, Hard Rock Café, City Barbeque, and Hattie B’s and has already proved to be a huge asset. For instance, a sensor deployment saved $35,000 to $50,000 worth of inventory in a Hattie B’s location when downtown Nashville experienced a sudden power outage in 2018. The LoRa-based alert system immediately notified store management, allowing them to act quickly and prevent food spoilage.

Reducing global food spoilage is a monumental task. From farms to grocery stores and restaurants, technology must play a critical role, ensuring food remains at a safe temperature, preventing unnecessary spoilage. In the era of connectivity, businesses will turn to LoRa-based IoT deployments for its flexibility, durability and ability to provide real-time information to employees and decision makers to not only maintain strict industry standards in food safety, but to also pass savings on to their valued customers.

food waste

Nearly 40% of U.S.-produced food is not consumed, according to a 2018 report by The Center for Biological Diversity. In addition, retailers are named as the largest culprits when it comes to food waste. IBM estimates that supermarkets tossed about 16 billion pounds of food last year alone. The technology company is working to get more involved in this problem and is holding the Food Waste Developer Challenge in an effort to find solutions to help reduce waste.

“Often, innovation comes from unexpected places. IBM’s sponsorship of the Food Waste Developer Challenge encourages developers to use their unique expertise toward solving some of society’s hardest problems,” says John Walicki, senior technical staff member, CTO IoT developer advocacy at IBM. “We hope to ignite an open community of impassioned developers to create solutions that improve the food supply chain and reduce food waste.” In a Q&A with Food Safety Tech, Walicki explains the important role that technology could play in stopping the ongoing food waste problem.

Food Safety Tech: What are the biggest challenges in addressing food waste?

John Walicki: One big issue is that the data around a product’s age, origin and journey lies with different parties or isn’t being tracked at all. Without shared visibility into these product attributes, at all stages of their life, it’s hard for grocers and producers to optimize how they sell and fulfill each item to guard against waste. And while less waste has a direct impact for the bottom line, more than ever, it has just as big of an impact in the mind of the increasingly belief-driven customer. According the 2018 Edelman Brand Survey, nearly two-thirds of consumers now choose, switch to or boycott a company based on its stand on societal issues, up from 51% in 2017.

FST: What is the goal of IBM’s Food Waste Developer Challenge?

Walicki: The goal of the challenge is to excite and crowd-source the minds of the developer community to create creative cloud-based, AI-enabled solutions for reducing food waste. For example, developers in the challenge have access to open-source code patterns for IoT, blockchain, AI-enabled bots, and more from IBM they can leverage in creating a solution. Nearly all of these capabilities are available for free on the IBM Cloud.

FST: Where are the key areas in which the food industry should be collaborating to solve these issues?

Walicki: The supply chain is the area [that] a lot of food retailers and producers are looking at. Better visibility into where the food is coming from, when, and its conditions are key in understanding when food will perish, etc. This involves collaboration from every partner all the way from the farm to when the customer purchases the product. The food chain is such a connected eco-system today. It’s really a team game in terms of generating solutions.

In addition, retailers are working to get better visibility into real-time on-hand inventories, so they can better know exactly how much of a certain product they have, so they can take prescriptive action if needed. More and more this type of insight requires the integration of data across many systems, both cloud-based and not. This means tight collaboration for food retailers internally and with suppliers.

How Proper Record Keeping Can Help Reduce Food Waste in the Supply Chain

By Jordan Anderson

Jordan Anderson, PAR Technology Corp.

One stringent component of FSMA and the Final Rule on Sanitary Transportation of Human and Animal Food is record keeping. Depending on the type and size of business, the FDA can demand proof of record anywhere from under one year and upwards to two years, all while needing to address their inquiry within 24 hours. Failure to do so will be considered a “prohibited act” and violators can be tried for civil and criminal penalties.
This new rule, put in place by the FDA, will put immense pressure on the food transportation industry, not only to make food safety a priority, but also to ensure that proper food safety practices and measures are being properly implemented, by way of record keeping.

While the litany of rules and regulations pertaining to record keeping best practices is intense, let us break down the basic requirements applying to records in layman’s terms:

  • If HACCP procedures aren’t documented, it didn’t happen
  • Records must be verbatim accounts of what happened
    • The need for real-time recording is paramount
  • Corrective actions must be executed immediately if an issue occurs
    • If not, liability risk increases exponentially

Companies must determine the most efficient and plausible manner by which they will comply. Traditional storage of records in filing cabinets and input of data in spreadsheets is antiquated, and leads to errors and the potential for misplaced records. Now, more than ever, is the time for businesses along the food chain to deliver value to their organization via digital technologies and automated data gathering solutions. This will ensure constant visibility and ensure quality control throughout the process from farm to fork.

Where Does Waste Happen?

While covering a lettuce farm in central California, National Geographic discovered that numerous loads were dumped each day due to procedural mistakes , including improperly filled, labeled and sealed containers.1 Due to the mishaps, the loads were then dumped. Between April and November that year, the local Waste Authority landfilled 4–8 million pounds of fresh vegetables from those fields.

The Food and Agriculture Organization (FAO) estimates that:

  • 54% of world food waste occurs during production, handling and storage
  • 46% occurs during processing & distribution

These numbers are not only staggering, but they illustrate the seriousness of this issue.

Many of these mishaps occur when standard recording procedures are done manually, which leads to improper documentation that invalidates the integrity of shipments—to which the above figures illustrate and corroborate.

But can shippers, loaders, receivers and the like secure their procedures and eliminate wasted product by implementing stricter digital HACCP solutions?

Lost Food

While improper execution of best practices can lead to FDA imposed sanctions and profit loss, it also perpetuates the problem of food waste globally. This issue has become an epidemic and one that greatly affects the lives of many.

In a recent National Geographic article, The Food and Agriculture Organization (FAO) suggests the following:1

  • One-third of food produced for global human consumption is annually lost or wasted along the supply chain
  • Food waste equates to 2.8 trillion pounds each year, which is enough to feed 3 billion people per year

Consider this: The World Food Programme estimates that nearly 795 million people in the world do not have access to the proper amount of food needed to live a healthy, active life, which equates to roughly one in nine people on earth.

The amount of waste created along the supply chain each year is enough to feed the hungry and malnourished people of the world three-times over. While waste is inevitable, even a 50% improvement would be able to feed those most in need.
We understand the nature of business is overcoming competition while expending the least capital possible, ultimately leading to profit. However, food-related businesses along the supply chain must ask themselves whether or not they are their own competition. Are best practices being properly executed? How can they ensure this in order to mitigate waste?

Ultimately, however, it becomes a human issue. Companies must be responsible and possess the empathy to understand this. While domestically we may not feel the effects of global hunger as much as other third-world countries, these businesses must be aware of the epidemic in order to elucidate this topic while simultaneously maximizing its businesses potential.

By leveraging new food safety solutions such as mobile devices, the cloud, IoT, sensors and more, you can better protect your customers while also gaining a tangible ROI. Wherever consumers purchase and shop for food today, they are likely to find a larger selection than ever before. From the bread aisle to the cheese counter to the produce section, food options and manufacturing processes today are more diverse than ever. While variety is positive on a consumer and cultural level, it can create challenges for food safety from farm to fork.

Food Transparency Movement Driving Changes in Labeling

By Maria Fontanazza
No Comments
Dagan Xavier, Label Insight

Recently the Grocery Manufacturers Association (GMA) and the Food Marketing Institute (FMI) announced an initiative to reduce the amount of confusion that consumers experience regarding the “sell by”, “use by” and other date-specific labeling on food packaging. It is also part of an effort to reduce food waste.

The new initiative is completely voluntary, but GMA and FMI are hoping that retailers and manufacturers adopt the standard by the summer of 2018. It streamlines the labeling terminology to two simple phrases:

  • BEST If Used By”. Describes product quality, indicating the date by which the product may not taste or perform as expected but it is still safe to consume
  • USE By”. Applies to highly perishable products and/or products that have a food safety concern over a period of time that warrants a date by which the products should either be consumed or discarded

A variety of factors well beyond “sell by”/”use by” dates contribute to consumer confusion. The following Q&A is a brief discussion with Dagan Xavier, co-founder and vice president, customer intelligence at Label Insight on the impact of incorrectly labeling products (erosion of brand trust) and the challenge food companies face in providing transparent information on their products.

Food Safety Tech: How is the demand for transparency both from consumers and regulators changing the food product labeling landscape?

Dagan Xavier, Label Insight

Dagan Xavier: Transparency sounds easy, but in reality, it is complex. For companies, managing compliance and consumer demands is not cut and dry.

Thankfully, brands and consumers are usually on the same page. But there are times when it’s not the case—and that causes trust issues. For one, brands need to use specific, compliant wording. That wording can sometimes be more complex than a preferred consumer-friendly phrasing. For example, USDA’s proposed labeling of GM-containing products refers to them as “genetically engineered.” Except, consumers are far more familiar with the term “genetically modified.”

Regardless of these nuances, regulations around transparency are in place to help consumers. The regulations set clear definitions about what products or ingredients can or cannot qualify for a labeling claim.

We currently live at a time where there is a general distrust of the food industry from consumers. Having strict regulations in place that add factual meaning behind claims is incredibly important. Meaningful and understandable claims, logos, and certifications are slowly beginning to help build trust back up from consumers.

FST:  What challenges are food companies facing in labeling their products?

Xavier: One of the biggest hurdles companies face in labeling is fitting as much information as possible on the package. Between mandatory components (like allergens, nutrients, ingredients) and desired content (marketing copy and images), something almost always gets left off. What gets left off? It tends to be sourcing facts, “Made in America” logos, and other data that consumers find valuable but rank lower on a brand’s priority list.

In reality, 100% complete product information is nearly impossible to fit within the confined space of most product packaging.

The good news is that according to a recent study by Label Insight, most consumers (88%) say they would be interested in accessing a complete set of product information digitally.

SmartLabel (an initiative by the Grocery Manufacturers Association) is an easy solution. SmartLabels save companies space on their packaging, while still allowing them to communicate all product information with consumers digitally.

Most consumers (79%) say they are very likely or somewhat likely to use SmartLabel technology if it was offered by a brand. 44% say they would trust a brand more if it participated in the GMA SmartLabel initiative.

FST: Related to labeling, what are the complicating factors when a company is producing organic, GMO-free, gluten free, etc.—especially when working with suppliers?

Xavier: Having a trusting relationship and open communication with suppliers is key.

Because regulations around organic and gluten-free are so stringent here in the United States, brands need to rely on their suppliers to have ongoing robust certification audits, inspections, documentation and renewal programs.

We expect regulations around GMO-containing products to follow suit.

For companies with dozens of suppliers, it can get tricky managing the documentation of certifications. This is especially complicated if suppliers are overseas and their audits are not delivered through the same certifying agencies that retailers or importers would like.

Adding logos and certifications to packages can be expensive and add risk to brands if a supplier falls out of compliance. In the end, it is important for both brands and suppliers to have robust documentation and a good communication channel. This ensures that all information on-pack is always the most accurate information for consumers and retailers.
