If you track your gluten intake, you probably already know about the Nima Portable Food Sensor. It works to measure gluten amounts in your food when you place a sample of your meal into its testing canister. Bosch’s X-Spect scanner is a similar tool; you can measure your food’s freshness in addition to recognizing cloth type. It will even detect a stain on your clothes and instruct your washing machine on how to remove it. If your food is rotten, the scanner will tell you.
