According to the Reviewed website, for people who are allergic to gluten, a meal or a meal at a newly opened restaurant means a real gamble. A startup company launched an easy-to-use gluten detection tool to relieve gluten allergy people from eating unfamiliar food. The glutenin detection tool, called Nima, is a rechargeable, triangular device that fits into a tote bag or bag. Although it looks like magic, Nima takes advantage of traditional science – just putting a beautiful, intelligent “coat†on traditional science. The Reviewed staff first heard about Nima about 2 years ago, and now the product has been developed and will soon be sold through retailers. At the Smart Kitchen Summit in Seattle, the Reviewed staff piloted Nima. Nima staff even conducted live demonstrations. On the surface, users are very interested in Nima. Many users even tell staff about stories of unexpected allergens when they or family members eat at a restaurant or eat convenience food. According to Reviewed, Nima developers call it a sensor, which may be misleading to detect whether a food contains gluten or simply point it at food. In fact, using Nima to detect food is more like using a pregnancy tester instead of a metal detector. To detect if gluten is present in the food, the user must place the food equivalent to the size of the peas in a dedicated test container. The container uses an antibody-based detection technique to detect the presence of gluten in the food, and gluten can activate the test strip outside the container within 2 to 3 minutes. Nima will “read†the test strip. If the gluten content of the food is below 20 ppm (parts per million), the external display will show a smiley face. The detection of special containers is not reusable, and the price is about 5 US dollars (about 33.7 yuan). A Nima representative said they expected regular users to test food 2-3 times a week. A lot of attention is recognized for Nima's user-friendly design and marketing efforts. There are many other gluten detection tools on the market – such as EZ Gluten and GlutenTox, but Nima researchers say their tools do a better job of detecting gluten. According to Reviewed, a companion app allows users to share test results and help other gluten-allergic people choose the right restaurant to eat. The first generation of Nima will be available for sale later this year at a price of $279 (approximately RMB 1,880), including a dedicated test container. Although Nima can only detect gluten, the company said that sensors for detecting peanuts and milk will come out next year.
