No time for lunch when preparing for work the next day? It's ok! Soon you may be able to prepare your lunch a year in advance. American researchers have discovered a natural preservative that is powerful enough to keep food fresh for long periods of time. However, this natural preservative is effective only for meat, fish, eggs and dairy products and does not keep vegetables and fruits from rot. This magical preservative is called "bisin" and is present in some innocuous bacteria. Dan O'Sullivan, a microbiologist at the University of Minnesota, discovered for the first time the presence of biscin in the study of human intestinal flora. It is naturally produced from some innocuous bacteria and can eliminate bacteria that cause food spoilage and prevent the growth of deadly bacteria including E. coli, Salmonella and Listeria. In some cases, Bissin-added foods do not even need to be put in the refrigerator and can be stored at room temperature for several years. O'Sullivan said: "It looks better than the previous preservatives, because it does not affect the nutritional value of food, and we do not add chemicals to it, just add a natural ingredient." Researchers said that this Preservatives prevent meat, fish, eggs, and dairy products from spoiling and extend the shelf-life of seafood, cheese, and canned foods, which are as effective as red wines and salad dressings that have been opened. Bissin and the preservative nisin are "close relatives". Nisin is widely used in the preservation of processed cheeses, which can make processed cheeses last for decades. Therefore, this new preservative does not need to undergo pharmaceutical testing before it is put on the market. Researchers at the University of Minnesota have applied for this preservative patent. They are negotiating with food manufacturers and it is expected that foods containing this preservative can be marketed within three years. (Hu Xuanyi compiled)
