Keychain detector catches food allergens before it’s too late

More than 50 million Americans display food reactions. Each year there are an estimated over 20,000 food allergy-related emergency department visits in the United States, including 90,000 cases of anaphylaxis. The best way to manage food allergy is to avoid products that contain allergen. But avoidance isn’t always possible because food can be mislabeled or cross-contaminated.
Meet iEAT (integrated Exogenous Antigen Testing) a $40 portable allergen-detection system that consists of a disposable kit to extract allergens from food and an electronic keychain analyzer for allergen detection. In less than 10 minutes, the iEAT completes food analyses and sends the results to a cloud server. The prototype was used to detect five model allergens from wheat, peanuts, hazelnuts, milk and egg white. Testing on food items from local restaurants revealed unexpected findings such as gluten in “gluten-free” dishes and egg protein in beer. The technology is being expanded to detect additional allergens, pesticides and environmental hormones.
