Technology keeps fresh food for years

Scientists have discovered a natural preservative that can help keep foods like fish, meat, milk, etc. fresh for years.

Researchers at the University of Minnesota have discovered that a new preservative, called bisin , can help increase the uptake of fresh produce for many years. This preservative works well for bottles that have opened the lid or salad has not eaten.

Natural bisin preservatives can help preserve sandwiches for longer.

The finding could create a revolution in the way housewives are today, and may reduce millions of tons of food that is discarded annually due to expiration or inadequate storage.

According to the Daily Mail , preservative bisins, found in some innocuous bacteria, are capable of inhibiting the growth of harmful bacteria including e-coli, salmonella, etc. This preservative Can help increase the use of a variety of foods such as seafood, dairy and canned food.

In some cases, bisins can help preserve food for many years without refrigeration. However, bisins can not preserve fruits and vegetables from rotting as these foods break down in a completely different way.

Dr Dan O'Sullivan, an Irish microbiologist and member of the research team, revealed that bisin was found to be very fl exible when they were culturing a bacterium in the human gut. .

' Bisin seems to be much better than today's preservatives. It does not affect the nutritional quality of the food, as it is not a chemical but a natural ingredient, " said Dr. Dan O'Sullivan.

Currently, the University of Minnesota team has been granted a bisin patent and they are negotiating with food manufacturers. It is expected that the first products using bisin preservative will be available in the market within the next 3 years.
