Frozen food demand has skyrocketed. Although COVID-19 was a catalyst, there are many reasons why the trend will likely continue going forward. The pandemic forced people to eat at home more, which was largely responsible for the hike in food sales, especially frozen goods. Higher availability and food quality enhancements have also contributed to the spike, prompting suppliers to upgrade and expand cold storage warehouse solutions—whether that means creating extra space or utilizing existing space more effectively.

One of the more important changes, prioritized across the industry, is food preservation and safety. It has always been crucial that frozen food reaches its destination clean, healthy and still frozen — just as it went in. However, preliminary data from the CDC’s Foodborne Diseases Active Surveillance Network reveals that foodborne illnesses are up 15%. The primary or most common form is Salmonella, but COVID-19 has consumers and food safety professionals thinking more closely about cleanliness and proper sanitation.

It has pushed a tight focus on safety overall, with new innovations looking to enhance sector controls.

Necessity Breeds Creativity

Recent events have played a role in the industry’s continued focus on safety, but so have consumer demands, as more and more people look to frozen meals, foods and items as part of their normal routines.

People love convenience. But as the pandemic hit, and people were forced to isolate and remain home more, and restaurants and stores closed as a safety precaution. What was once about convenience became even more about safety. People still wanted freedom and ease of use, but it wasn’t a necessity nor was it a priority. Safety became even more important, which is why curbside pickup, deliveries and online transactions became so popular.

What does this have to do with frozen foods? Everything. Because of the pandemic, we’ve all had to eat at home more often, which means preparing meals, snacks and other items, with minimal exposure to the outside world or even local grocery stores. Naturally, consumers turned to easily cooked and pre-prepared frozen foods and meals.

Safety is the Priority

It makes sense that more frozen foods being purchased and consumed would shift priorities in the market. In a 2021 report released by Acosta, 14% of respondents say they consume frozen food nearly all the time. About 46% say they consume frozen foods often.

During the pandemic, the share of U.S. core frozen food consumers rose to 39% in 2020, up from 35% in 2018. “Core” consumers are defined as those who either eat frozen food daily or every few days.

What’s more, 42% of households that buy frozen foods did so online, up from 23% in 2018. And online frozen food sales jumped 75% last year, with the top purchases including frozen dinners and entrees, meat, poultry and even seafood.

Instead of restricting eating habits, consumers have turned to frozen foods to spruce up their meals, create new at-home dishes, and so on. It has boosted the demand for all kinds of frozen foods. It also necessitates the need for improved quality and safety. Implementing and maintaining strict controls as to how the food is transported, handled and preserved, can prevent contamination on all fronts.

With that rise in dependence, on frozen foods specifically, it is imperative that supply chain operators are delivering goods in a safe, healthy condition. Allowing foods to thaw during the transport process can introduce more problems than just contamination, especially with COVID remaining a major influence.

Imagine how bad it would be if the world experienced a major foodborne outbreak, right now. Most scenarios can be prevented through smarter food handling and better, data-driven controls.

New methods are being implemented to chill and prepare foods earlier on in the supply process. Many cold chain providers are adopting low-temperature chillers, like a food processing chiller, for example. They can freeze prepared foods quickly to ensure they are safe, disinfected and stored appropriately. From there, it’s just a matter of keeping them cold-locked during transport, storage, delivery, and beyond. That’s precisely where some of the latest innovations come into the picture.

Cold Storage Warehouse Innovations

To keep up with the demand and ensure frozen foods and other goods stay fresh in the cold chain, the industry is seeing rampant innovation, thanks to modern technologies. Think IoT-equipped fleets and storage systems to facilitate faster time to market and better transparency. Or, machine learning and AI-driven tools that help discern bottlenecks, locate faster and more effective solutions, and so on.

At the heart of it all is data, or rather digital content and information. The smarter and more contextually driven operations are, the better efficiency is all around. The following are some of the technologies making this happen:

  • IioT. The Industrial Internet of Things (IIoT) involves connected devices that continually collect, transmit and sometimes process performance and contextual data. In the cold chain, it can be used to track goods, prevent theft or fraud, monitor processes, discover bottlenecks and more.
  • Machine Learning. An offset of artificial intelligence, machine learning and neural networks can be used to ingest and analyze massive swarms of data in ways, and at speeds, that humans never could. What’s more, the technology can empower highly advanced automation systems to take action, respond, or act based on algorithmic rulesets.
  • Electric and autonomous vehicles. Revolutionizing logistics and conventional transport, electric and fully autonomous vehicles will significantly improve fleets with better safety, stop-free trips and more.
  • Smart shelving. Imagine Amazon’s Kivo bots, or something similar, implemented within cold storage warehouses. The entire system is designed to improve inventory management, order picking, and general logistics.
  • Co-bots. Beyond delivery, ground-based drones or advanced robots can be used to transport and move heavy goods, large or bulk orders, and organize the warehouse. When outfitted with the appropriate hardware, they can reach high shelves and storage areas or move through hazardous locations, improving safety for manual workers.

Innovation Brings New Challenges

Of course, there are the general challenges facing the cold storage industry, such as how to keep foods fresh throughout the journey, proper packaging solutions, and maintaining more sanitary conditions, but there are new challenges presented by the adopted technologies.

For example, IIoT devices aren’t typically designed to be exposed to extremely frigid temperatures, which may sometimes affect the measurements and data collected. A malfunctioning device can lead to serious problems, especially when it’s the sole method for maintaining temperatures and ensuring food is properly stored.

Bringing these devices up to a sufficiently resistant level is a challenge, as is keeping them running optimally. Failing to do so could increase food contamination, the spread of foodborne illness, or worse.

Another challenge involves the expansion or development of new cold storage facilities. As warehouses and locations grow to accommodate larger inventories, the cold storage systems must become more sophisticated and powerful. What’s more, even the slightest temperature drop because of a system failure can have sweeping repercussions in such a large facility. A single refrigeration unit going down can drop temperatures across the entire warehouse.

Designing smarter spaces to keep the cold temperatures contained is one solution. Installing the supporting systems is another, which keeps things operational even when a negative scenario plays out. Automation and smart, data-driven technologies can be incredibly helpful in this area.

Finally, the bigger the cold storage solution, the higher the power draw and the more resources needed to keep things running. In turn, it’s necessary to install and implement smart technologies to reduce the carbon footprint. Cutting energy usage wherever possible becomes vital to sustainability. It can call for solutions like smart or timed lighting, smart thermostats for the refrigeration units, or upgraded systems that reduce emissions — think electric fleets and renewable energy platforms.

Backup solutions are even a part of the mix, when power outages can bring an entire operation down in seconds, and expose food to long-term risk.

Frozen Food Demand: A Steady Climb

Things may change, and there are never any guarantees, but right now it looks as though high demand for frozen food will continue, and may even grow steadily. Market conditions are partly responsible, but consumers are now more focused on quality and healthy foods, above eating out or ordering in. As the economy continues to open, people will want to get back out there and explore. But that doesn’t necessarily mean frozen food demand will decline.

Cold chain and cold storage warehouse providers must be prepared for the continued growth, which includes finding new and innovative ways to preserve, package and safely store frozen foods.

Robots Serve Up Safety in Restaurants

Perhaps the top takeaway from the worldwide COVID-19 pandemic is that people the world over realize how easily viruses can spread. Even with social distancing, masks and zealous, frequent handwashing, everyone has learned contagions can cycle through the atmosphere and put a person at risk of serious, and sometimes deadly, health complications. In reality, there are no safe spaces when proper protocols are not followed.

The primary culprit in transmission of norovirus, according to the CDC, is contaminated food. “The virus can easily contaminate food because it is very tiny and spreads easily,” the CDC says in a fact sheet for food workers posted on its website. “It only takes a very small amount of virus to make someone sick.”

The CDC numbers are alarming. The agency reports about 20 million people get sick from norovirus each year, most from close contact with infected people or by eating contaminated food. Norovirus is the leading cause of disease outbreaks from contaminated food in the United States, and infected food workers cause about 70% of reported norovirus outbreaks from contaminated food.

The solution to reducing the transmission of unhealthy particles could be starting to take shape through automation. While robots have been used for the past few years in food manufacturing and processing, new solutions take food handling to a new level. Robots are no longer in the back of the house in the food industry, isolated in packaging and manufacturing plants. They are now front and center. The next time you see a salad prepared for you at a favorite haunt, you may be watching a robot.

“The global pandemic has altered the way that we eat,” said Justin Rooney, of Dexai Robotics, a company that developed a food service robotic device. Reducing human contact with food via hands-free ordering and autonomous food serving capabilities has the potential to reduce the spread of pathogens and viruses, and could help keep food fresh for a longer period of time.

Painful Pandemic

Increased use of automation in the foodservice industry might be one of the salvations of the COVID-19 pandemic. In an industry searching for good news, that might be the silver lining in an otherwise gloomful crisis.

Job losses in the restaurant industry have been brutal. By the end of November, nearly 110,000 restaurants in the United States had closed. A report by the National Restaurant Association said restaurants lost three times more jobs than any other industry since the beginning of the pandemic. In December, reports said nearly 17% of U.S. restaurants had closed. Some restaurants clung to life by offering outdoor dining, but as winter set in, that option evaporated. Some governors even demanded restaurant closures as the pandemic escalated in late fall.

Restaurants have faced a chronic labor shortage for years. Despite layoffs during the pandemic, many former foodservice employees are electing to leave the industry.

Teenagers, for instance, and some older workers are staying away for health and safety reasons. Some former workers are also finding out that they can make more money on unemployment benefits than by returning to work. Restaurant chains have hiked wages, but filling positions still remains a challenge.

Automated Solutions

Restaurants began dancing with the idea of robots nearly 50 years ago. The trend started slowly, with customers ordering food directly through kiosks. As of 2011, McDonald’s installed nearly 7,000 touchscreen kiosks to handle cashiering responsibilities at restaurants throughout Europe.

As technology has advanced, so has the presence of robots in restaurants. In 2019 Seattle-based Picnic unveiled a robot that can prepare 300 pizzas in an hour. In January, Nala Robotics announced it would open the world’s first “intelligent” restaurant. The robotic kitchen can create dishes from any cuisine in the world. The kitchen, which is expected to open in April in Naperville, Illinois, will have the capability to create an endless variety of cuisine without potential contamination from human contact.

Dexai designed a new robotic unit that allows for hands-free ordering that can be placed through any device with an Internet connection. The robot also includes a new subsystem for utensils, which are stored in a food bin to keep them temperature controlled. This ensures that robot is compliant with ServSafe regulations. The company is working on improving robot system’s reliability, robustness, safety and user friendliness. The robot has two areas to hold tools, a kitchen display system, bowl passing arm, an enclosure for electronics and two refrigeration units. It has the unique ability to swap utensils to comply with food service standards and prevent contamination as a result of allergens, for example.

Why Automation

Many industries have been impacted by advancements in automation, and the foodservice industry is no different. While initially expensive, the benefits over time can provide to be worth the investment.

One of the most significant advantages, particularly important in the post-COVID era, is better quality control. Automated units can detect issues much earlier in the supply chain, and address those issues.

Automation can also help improve worker safety by executing some of the more repetitive and dangerous tasks. Robots can also boost efficiency (i.e., a robot used for making pizza that can press out dough five times faster than humans and place them into ovens) and eliminate the risk of injury. Robots are also being used to make coffee, manage orders and billing, and prepare the food. Robots can also collect data that will help foodservice owners regarding output, quantity, speed and other factors.

“Alfred’s actions are powered by artificial intelligence,” according to Rooney. “Each time Alfred performs an action, the associated data gets fed into a machine learning model. Consequently, each individual Alfred learns from the accumulated success and failures of every other Alfred that has existed.” Dexai plans to teach the robot to operate other commonly found pieces of kitchen equipment such as grills, fryers, espresso machines, ice cream cabinets and smoothie makers.

Unrelenting Trend

Automated solutions might have come along too late to save many restaurants, but the path forward is clear. While they are not yet everywhere, robots are now in play at significant number of restaurants, and there is no turning back. Any way you slice it, robots in restaurants, clearly, is an idea whose time has come.

Is Programmatic Commerce the Next Wave in Supply Chain Tech?

While COVID-19 exposed disconnects in the food supply chain, it also served as an overdue catalyst for rapid technology adoption. Food manufacturers, distributors and retailers were forced to grapple with consumer behaviors that—previously expected to occur over five years— changed within about five weeks. Faced with unprecedented demand, channel shifts and rapidly changing consumer purchasing behaviors, forward-looking brands and retailers have started to transform their business models to become highly responsive and agile.

A new approach called “programmatic commerce” may be the key to faster market insights and pivots. Taking cues from past attempts to digitize the supply chain from end-to-end, programmatic commerce uses artificial intelligence (AI) and machine learning (ML) to connect and unify critical business data across food manufacturers, distributors and retailers using common retail portals, BI and CRM tools as well as other data resources and platforms.

With a real-time unified view of channels and activity, programmatic commerce has the potential to create fully automated trade processes to optimize production, inventory management, logistics, promotions and more for both upstream and downstream supply chain activities.

To achieve the potential of programmatic commerce, real-time or near real-time data sources must be easily integrated, unified and displayed. This is in stark contrast to previous attempts to create end-to-end supply chain visibility, which often required custom or manual integrations, had costly and lengthy implementation requirements and necessitated custom reporting.

The programmatic approach is already gaining traction, enabling retailers to leverage AI and ML technology to optimize supply chains. But the real value is in taking it one step further—to tap into rich customer data, understand rapidly changing consumer behaviors and ultimately—to predict and personalize shopping experiences at scale.

Tracking and Adapting to Evolving Consumer Journeys

Consumers increasingly demand greater choice, control, personalization and transparency and companies must continuously create, track and manage a 360º view of customers’ shopping journeys to stay ahead of these trends. Fortunately, real-time data and analytical capabilities are available to supply the critical information they need to implement a programmatic commerce approach.

Among the shifts companies must track as a result of COVID-19 is the explosion in online grocery shopping. In November 2020, U.S. grocery delivery and pickup sales totaled $5.9 billion and a record high 83% of consumers intend to purchase groceries online again, signaling this trend continues as the pandemic lingers on.1 By 2025, online grocery sales are predicted to account for 21.5% of total grocery sales, representing more than a 60% increase over pre-pandemic estimates.2 A permanent shift toward online grocery shopping can be expected as consumers’ shopping and fulfillment experience continues to improve.

For consumers still shopping in stores, the pandemic also drove switches in primary physical store locations. In the United States, an estimated 17% of consumers shifted away from their primary store since the start of the pandemic.3 This was driven by increased work-from-home, which eliminated commuting routes and made different store locations more convenient, including ones closer to home.

Given the multitude of changes impacting consumer journeys during the pandemic, it is imperative that companies track relevant purchase drivers and considerations of each purchase occasion, while also taking into account their recent shopping experience. This creates the need for consistent, seamless and relevant experiences across both digital and physical channels that aligns all touchpoints with the consumer as part of their “total commerce experience.”

Multiple retailers are already pursuing this approach in the hope of retaining their “primary store” status across the totality of their consumers’ shopping experiences. Walmart recently launched a new store format to help achieve “seamless omni-shopping experiences” for its customers through a digitally enabled shopping environment. Customers can use the Walmart app to efficiently find what they’re looking for, discover new products, check pricing, and complete contactless checkout.4 Data tracked on these customers can eventually be used to create personalized recommendations and in-store activations and assistance based on their purchase history and in-store experience.

Conversely, the “digital store” is also being reimagined to align with consumers’ in-store experience to create a seamless shopping experience. For example, personalized meal planning service The Dinner Daily now offers the ability for its members to order recipe ingredients directly from Kroger and other Kroger-owned stores through The Dinner Daily app.5 Integrated data from multiple shopping platforms and consumer touchpoints can provide food manufacturers and retailers with shopper profiles, consumer experiences, and purchase history along with inventory status and other inputs to ultimately build personalized customer experiences and enhance shopper loyalty.

Applying Programmatic Commerce to Deliver Personalization to Consumers

Once armed with real-time data in a uniform format from sources ranging from consumer search analytics to retailer promotional pricing, a programmatic commerce approach can provide companies with predictive understanding of demand and supply to optimize decision making from raw materials through production through retail or direct-to-consumer.

Using online grocery shopping as an example, consumer personalization can be delivered through the accurate prediction and display of items relevant to each shopper based on shopping history, preferences, current cart selections, and other inputs such as real-time availability, marketing promotions and more.

Innovations are already in the market, including Halla, a data science company that developed a grocery-specific personalization algorithm that works with grocery retailer e-commerce platforms to create smart recommendations based on understanding of individual shoppers’ product usage and preferences.6 Another example is the Locai Solutions digital grocery platform, which applies AI to personalize recipe recommendations based on consumer preferences and purchase history and determines ingredients and quantities needed for easy incorporation into their shopping cart.7

The Path Ahead: Accelerating Technology Adoption in the Food Industry

AI and ML are already reducing waste across supply chains and enabling consumer personalization. However, currently only about 12% of retail decision-makers feel they are very effective at providing these experiences to customers and only 10% have access to the real-time data needed to achieve this goal.8

Modern programmatic commerce platforms (see Figure 1) can effectively bridge information gaps, improve inventory and distribution to prevent shortages or overages and help companies be data-ready to meet actual demand. Beyond this, a programmatic approach unlocks the next stage of customer satisfaction and loyalty, personalizing the experience during and after the pandemic.

How a History of Slow Technology Adoption Across Food Supply Chains Nearly Broke Us

By Are Traasdahl

Are Traasdahl, Crisp

The COVID-19 crisis has exacerbated existing disconnects between food supply and demand. While some may be noticing these issues on a broader scale for the first time, the reality is that there have been challenges in our food supply chains for decades. A lack of accurate data and information sharing is the core of the problem and had greater impact due to the pandemic. Outdated technologies are preventing advancements and efficiencies, resulting in the paradox of mounting food insecurity and food waste.

To bridge this disconnect, the food industry needs to implement innovative AI and machine learning technologies to prevent shortages, overages and waste as COVID-19 subsides. Solutions that enable data sharing and collaboration are essential to build more resilient food supply chains for the future.

Data-sharing technologies that can help alleviate these problems have been under development for decades, but food supply chains have been slow to innovate compared to other industries. By reviewing the top four data-sharing technologies used in food industry and the year they were introduced to food supply chains, it’s evident that the pace of technology innovation and adoption needs to accelerate to advance the industry.

A History of Technology Adoption in the Food Industry

The Barcode – 19741
We’re all familiar with the barcode—that assemblage of lines translated into numbers and letters conveying information about a product. When a cashier scans a barcode, the correct price pops up on the POS, and the sale data is recorded for inventory management. Barcodes are inexpensive and easy to implement. However, they only provide basic information, such as a product’s name, type, and price. Also, while you can glean information from a barcode, you can’t change it or add information to it. In addition, barcodes only group products by category—as opposed to radio-frequency identification (RFID), which provides a different code for every single item.

EDI First Multi-Industry Standards – 19812
Electronic data interchange (EDI) is just what it sounds like—the concept of sharing information electronically instead of on paper. Since EDI standardizes documents and the way they’re transferred, communication between business partners along the supply chain is easier, more efficient, and human error is reduced. To share information via EDI, however, software is required. This software can be challenging for businesses to implement and requires IT expertise to handle updates and maintenance.

RFID in the Food Supply Chain – 20033
RFID and RFID tags are encoded with information that can be transmitted to a reader device via radio waves, allowing businesses to identify and track products and assets. The reader device translates the radio waves into usable data, which then lands in a database for tracking and analysis.

RFID tags hold a lot more data than barcodes—and data is accessible in remote locations and easily shared along the supply chain to boost transparency and trust. Unlike barcode scanners, which need a direct line of sight to a code, RFID readers can read multiple tags at once from any direction. Businesses can use RFID to track products from producer to supplier to retailer in real time.

In 2003, Walmart rolled out a pilot program requiring 100 of its suppliers to use RFID technology by 2005.3 However, the retail giant wasn’t able to scale up the program. While prices have dropped from 35–40 cents during Walmart’s pilot to just 5 cents each as of 2018, RFID tags are still more expensive than barcodes.4 They can also be harder to implement and configure. Since active tags have such a long reach, businesses also need to ensure that scammers can’t intercept sensitive data.

Blockchain – 20175
A blockchain is a digital ledger of blocks (records) used to record data across multiple transactions. Changes are recorded in real-time, making the history unfalsifiable and transparent. Along the food supply chain, users can tag food, materials, compliance certificates and more with a set of information that’s recorded on the blockchain. Partners can easily follow the item through the physical supply chain, and new information is recorded in real-time.

Blockchain is more secure and transparent, less vulnerable to fraud, and more scalable than technologies like RFID. When paired with embedded sensors and RFID tags, the tech offers easier record-keeping and better provenance tracking, so it can address and help solve traceability problems. Blockchain boosts trust by reducing food falsification and decreasing delays in the supply chain.6

On the negative side, the cost of transaction processing with blockchain is high. Not to mention, the technology is confusing to many, which hinders adoption. Finally, while more transparency is good news, there’s such a thing as too much transparency; there needs to be a balance, so competitors don’t have too much access to sensitive data.

Cloud-Based Demand Forecasting – 2019 to present7
Cloud-based demand forecasting uses machine learning and AI to predict demand for various products at different points in the food supply chain. This technology leverages other technologies on this list to enhance communication across supply chain partners and improve the accuracy of demand forecasting, resulting in less waste and more profit for the food industry. It enables huge volumes of data to be used to predict demand, including past buying patterns, market changes, weather, events and holidays, social media input and more to create a more accurate picture of demand.

The alternative to cloud-based demand forecasting that is still in use today involves Excel or manual spreadsheets and lots of number crunching, which are time-intensive and prone to human error. This manual approach is not a sustainable process, but AI, machine learning and automation can step in to resolve these issues.

Obtaining real-time insights from a centralized, accurate and accessible data source enables food suppliers, brokers, distributors, brands and retailers to share information and be nimble, improving their ability to adjust supply in response to factors influencing demand.8 This, in turn, reduces cost, time and food waste, since brands can accurately predict how much to produce down to the individual SKU level, where to send it and even what factors might impact it along the way.

Speeding Up Adoption

As illustrated in Figure 1, the pace of technology change in the food industry has been slow compared to other industries, such as music and telecommunications. But we now have the tools, the data and the brainpower to create more resilient food supply chains.

Technology adoption, food industry

Given the inherent connectivity of partners in the food supply chain, we now need to work together to connect information systems in ways that give us the insights needed to deliver exactly the rights foods to the right places, at the right time. This will not only improve consumer satisfaction but will also protect revenue and margins up and down food supply chains and reduce global waste.

Machine Vision Training Tips to Improve Food Inspections

By Megan Ray Nichols

Megan Nichols

As machines become more intelligent, every industry on earth will find abundant new applications and ways to benefit. For the food industry, which has an incredible number of moving parts and is especially risk-averse, machine vision and machine learning are especially valuable additions to the supply chain.

The following is a look at what machine vision is, how it can play a role in manufacturing and distributing foods and beverages, and how employers can train workers to get the most out of this exciting technology.

What Is Machine Vision?

Machine vision isn’t a brand-new concept. Cameras and barcode readers with machine vision have long been capable of reading barcodes and QR codes and verifying that products have correct labels. Modern machine vision takes the concept to new levels of usefulness.

Barcodes and product identifiers have a limited set of known configurations, which makes it relatively straightforward to program an automated inspection station to recognize, sort or reject products as necessary. Instead, true machine vision means handlers don’t have to account for every potential eventuality. Machine vision instead learns over time, based on known parameters, to differentiate between degrees of product damage.

Consider the problem of appraising an apple for its salability. Is it bruised or discolored? Machine vision recognizes that no two bruises look precisely alike. There’s also the matter of identifying different degrees of packaging damage. To tackle these problems, it’s not possible to program machine vision to recognize a fixed set of visual clues. Instead, its programming must interpret its surroundings and make a judgment about what it sees.

The neural networks that power machine vision have a wide range of applications, including improving pathfinding abilities for robots. In this article, I’ll focus on how to leverage machine vision to improve the quality of edible products and the profitability of the food and beverage industry.

Applications for Machine Vision in the Food Industry

There are lots of ways to apply machine vision to a food processing environment, with new variations on the technology cropping up regularly. The following is a rundown on how different kinds of machine vision systems serve different functions in the food and beverage sector.

1. Frame Grabbing and 3-D Machine Vision
Machine vision systems require optimal lighting to carry out successful inspections. If part of the scanning environment lies in shadow, undesirable products might find their way onto shelves and into customers’ homes.

Food products sometimes have unique needs when it comes to carrying out visual inspections. It’s difficult or impossible for fallible human eyeballs to perform detailed scans of thousands of peas or nuts as they pass over a conveyor belt. 3-D machine vision offers a tool called “frame grabbing,” which takes stills of — potentially — tens of thousands of tiny, moving products at once to find flaws and perform sorting.

2. Automated Sorting for Large Product Batches
Machine vision inspection systems can easily become part of a much larger automation effort. Automation is a welcome addition to the food and beverage sector, translating into improved worker safety and efficiency and better quality control across the enterprise.

Inspection stations with machine vision cameras can scan single products or whole batches of products to detect flaws. But physically separating these products must be just as efficient a process as identifying them. For this reason, machine vision is an ideal companion to compressed air systems and others, which can carefully blow away and remove even a single grain of rice from a larger batch in preparation.

3. Near-Infrared Cameras
Machine vision takes many forms, including barcode and QR code readers. A newer technology, called near-infrared (NIR) cameras, is already substantially improving the usefulness and capabilities of machine vision.

Remember that bruised apple? Sometimes physical damage to fruits and vegetables doesn’t immediately appear on the outside. NIR technology expands the light spectrum cameras can observe, giving them the ability to detect interior damage before it shows up on the exterior. It represents a distinct advantage over previous-generation technology and human inspectors, both of which can leave flaws undiscovered.

Tips on Training Workers to Use Machine Vision

Implementing machine vision into a productive environment delivers major benefits, but it also comes with a potentially disruptive learning curve. The following are some ideas on how to navigate it.

1. Take Advantage of Third-Party Training Courses
Don’t expect employees to hit the ground running with machine vision if they’re not familiar with the fundamentals of how it works. Google has a crash course on machine learning, and Amazon offers a curriculum as well to help companies get their employees up to speed on the technology and how to use it.

2. Get the Lighting Right
Having the appropriate intensity of light shining on the food product is essential for the machine vision cameras to get a clear photo or video. The most common types of lighting for machine vision are quartz halogen, LEDs, metal halide and xenon lights. Metal halide and xenon are better for larger-scale operations because of their brightness.

Train employees to check the amount and positioning of the lighting before each inspection station starts up for the day, so that no shadows obscure products from view.

3. Single Out Promising Subject Matter Leaders
Companies today don’t seem to have much confidence in how well they’re preparing their workforce for tomorrow, including future innovations. According to Deloitte, just 47% of companies in the world believe they’re doing enough to train their employees on the technologies and opportunities of Industry 4.0.

Machine vision does not involve buying a camera or two, setting them up, then slapping the “autopilot” button. As products turn over, and manufacturing and distribution environments change and grow over time, machine vision algorithms require re-training, and you might need to redesign the lighting setup.

Employers should find individuals from their ranks who show interest and aptitude in this technology and then invest in them as subject matter experts and process owners. Even if an outside vendor is the one providing libraries of algorithms and ultimately coming up with machine vision designs, every company needs a knowledgeable liaison who can align company needs with the products on the market.

Machine Vision Is the Future of Food Inspections

The market for machine vision technology is likely to reach $30.8 in value by 2021, according to BCC Research.

It is important to remember that neither machine learning nor machine vision are about creating hardware that thinks and sees like humans do. With the right approach, these systems can roundly outperform human employees.

But first, companies need to recognize the opportunities. Then, they must match the available products to their unsolved problems and make sure their culture supports ongoing learning and the discovery of new aptitudes. Machine vision might be superior to human eyesight, but it uses decidedly human judgments as it goes about its work.

2020 Expectations: More Artificial Intelligence and Machine Learning, Technology Advances in Food Safety Testing

2018 and 2019 were the years of the “blockchain buzz”. As we enter the new decade, we can expect a stronger focus on how technology and data advances will generate more actionable use for the food industry. Food Safety Tech has highlighted many perspectives from subject matter experts in the industry, and 2020 will be no different. Our first Q&A of the year features Sasan Amini, CEO of Clear Labs, as he shares his thoughts on tech improvements and the continued rise consumer expectations for transparency.

Food Safety Tech: As we look to the year ahead, where do you see artificial intelligence, machine learning and blockchain advancing in the food industry?

Sasan Amini: AI, ML, and blockchain are making headway in the food industry through advances in supply chain management, food sorting and anomaly detection, and tracing the origin of foodborne outbreaks. On the regulatory side, FDA’s focus on its New Era of Smarter Food Safety will most likely catalyze the adoption of the above mentioned technologies. On the private side, a few of the companies leading the charge on these advancements are IBM and Google, working in partnership with food manufacturers and retailers across the world.

Along those same lines, another area that we expect to grow is the use of AI and ML in tandem with robotics—and the value of new troves of data that they collect, analyze and distribute. For example, robotics for the use of environmental monitoring of potential contaminants, sorting techniques and sterilization are valuable because they ensure that end products have been through thorough testing—and they give us even more information about the lifecycle of that food than ever before.

At the end of the day, data is only valuable when you can transform it into actionable insights in real-time with real-world applications, and we expect to see more and more of this type of data usage in the year ahead.

FST: Where do you think food safety testing technologies will stand out? What advancements can the industry expect?

Amini: In 2020, technology is going to begin to connect itself along the entire supply chain, bringing together disparate pieces and equipping supply chain professionals with action-oriented data. From testing advances that improve speed, accuracy and depth of information to modular software solutions to promote transparency, the food safety industry is finally finding its footing in a data-driven sea of technological and regulatory advances.

Right now, legacy testing solutions are limited in their ability to lead food safety and quality professionals to the source of problems, providing insights on tracking recurring issues, hence having a faster response time, and being able to anticipate problems before they occur based on a more data heavy and objective risk assessment tools. This leaves the industry in a reactive position for managing and controlling their pathogen problems.

Availability of higher resolution food safety technologies that provide deeper and more accurate information and puts them in context for food safety and quality professionals provides the food industry a unique opportunity to resolve the incidents in a timely fashion with higher rigour and confidence. This is very in-line with the “Smarter Tools and Approaches” that FDA described in their new approach to food safety.

FST: How are evolving consumer preferences changing how food companies must do business from a strategic as well as transparency perspective?

Amini: Consumers are continuing to get savvier about what’s in their food and where it comes from. Research suggests that about one in five U.S. adults believe they are food allergic, while only 1 in 20 are estimated to have physician-diagnosed food allergies. This discrepancy is important for food companies to consider when making decisions about transparency into their products. Although the research on food allergies continues to evolve, what’s important to note today is that consumers want to know the details. Radical transparency can be a differentiator in a competitive market, especially for consumers looking for answers to improve their health and nutrition.

Consumers are also increasingly interested in personalization, due in part to the rise in new digital health and testing companies looking to deliver on the promise of personalized nutrition and wellness. Again, more transparency will be key.

FST: Additional comments are welcome.

Amini: Looking ahead, we expect that smaller, multi-use, and hyper-efficient tools with reduced physical footprints will gain market share. NGS is a great example of this, as it allows any lab to gather millions of data points about a single sample without needing to run it multiple times. It moves beyond the binary yes-no response of traditional testing, and lets you get much more done, with far less. Such wealth of information not only increases the confidence about the result, but can also be mined to generate more actionable insights for interventions and root cause analysis.

This “multi-tool” will be driven by a combination of advanced software, robotics, and testing capabilities, creating a food safety system that is entirely connected, driven by data, and powerfully accurate.

“It’s time to look to the future of food safety once again,” declared Acting FDA Commissioner Ned Sharpless, M.D. and Deputy Commissioner for Food Policy and Response Frank Yiannas in a press statement released yesterday. Although progress has been made in implementing FSMA and with the development of the GenomeTrakr Network, the agency wants to move forward in taking advantage of the innovative technologies that will help make the food supply more digital, traceable and safer. With that effort comes the creation of a “Blueprint for a New Era of Smarter Food Safety”, which will speak to “traceability, digital technologies and evolving food business models”. Sharpless and Yiannas outlined the significant role that these components will play.

Digital technology in food traceability. Digital technologies could play a crucial part in rapidly identifying and tracing contaminated food back to its origin—changing the timespan from days or weeks to minutes or seconds. FDA intends to look at new ways that it can evaluate new technologies and improve its ability to quickly track and trace food throughout the supply chain. “Access to information during an outbreak about the origin of contaminated food will help us conduct more timely root cause analysis and apply these learnings to prevent future incidents from happening in the first place,” stated Sharpless and Yiannas. This means a shift away from paper-based systems.

Emerging technologies. Artificial intelligence (AI), distributed ledgers (no, they didn’t directly say “blockchain”), the Internet of Things, sensors and other emerging technologies could enable more transparency within the supply chain as well as consumer side of things. The FDA leaders announced a pilot program that will use AI and machine learning to assess food imports at the U.S. point of entry.

E-Commerce. “Evolving food business models”, also known as e-commerce, is growing fast and changing how consumers get their food. With food delivery introduces food safety issues such as those related to packaging and temperature control. FDA is exploring how it can collaborate with federal, state and local stakeholders to figure out ways to address these potential problems.

Sharpless and Yiannas emphasized the end-goal in keeping the food of American consumers safe. “So, welcome to the new era of smarter food safety that is people-led, FSMA-based and technology-enabled!”
