A goo microorganism is added to the food. It grows rapid becomes the dominant microorganism present in the food and inhibits the growth of bad microorganisms. As grows, it changes proteins or sugars or both in the food and makes it more delicious. Japanese people eat many fermented foods: soy sauce miso, natto, Japanese pickles. Japanese cuisine could not exist. Without these foods Recently, collaborating with a university, a company in Japan developed a special sheet coated with a good microorganism. When you wrap meat or fish in this sheet, the good microorganism protects the food from bad microorganisms. The food naturally begins to ferment without spoiling, and its taste becomes richer and more delicious. The sheet may also solve the food waste problem. Restaurants that use the sheet can keep extra food longer instead of throwing it away.
