Modern advances from computer chips to medical biotech use something called nanotechnology that deals with materials at an infinitesimally small size. Now, researches in the food industry are looking to this technology to improve the products they sell to consumers. This, according to Science News, which reports how one use of nanotechnology might be tiny sensors in food packages that change color when milk or cheese go bad. Another use might be tiny capsules that store antioxidants, or flavorings, in the foods until they are eaten. Whatever their use, many are excited about the possibilities of producing safer, and even smarter food, by working at the microscopic level.
