Lab methods for the analysis of adulterated food can be time-consuming, expensive and impossible to use in the field. A new study shows promising results for hand-held near infrared (NIR) spectroscopy tools. The investigated method proved to be very quick and highly accurate, and could open new possibilities for remote testing. This was shown in a study with oregano samples, a common target for food adulteration.

Turkish delight, baklava, halva, biscotti, mortadella, ice cream and many more delicious foods from around the world contain pistachios, which are pricey and therefore a popular target for food fraud. A recent article describes a method to detect spinach and green peas that often are used as a pistachio replacement due to their color and low price. The technique combines NIR (near infrared) spectroscopy and chemometric analysis and provides a method that is precise, fast and non-destructive.
