Worried about food rotten?Plant -based antibacterial spray only needs to "spray a spray" simply

Science Fiction Network June 21 (Wang Ziyu) The weather in summer is very hot, and many foods will easily become corrupted at high temperatures and breed bacteria. Once you are eaten by mistake, physical discomfort and poisoning will occur. To this end, researchers at Harvard and Rogers University have developed a new plant -based antibacterial coating that can be sprayed on food to keep fresh and washed it off before eating.

According to reports, this coating is composed of biological polymer fibers. In order to resist microorganisms such as E. coli and Listel bacteria, natural antibacterial agents such as li li oil, citric acid, and lactic acid spam peptide were also added. When you want to eat, this coating can be washed away just was washed.

The coating uses a process called a spinning spinning spinning, which can be produced on a large scale. When producing, it rotates from a heating device and can be applied to fruits, vegetables and meat.

Through the test, the researchers found that using this coating can extend the shelf life of butter fruit by 50%. Of course, this is not the first time that scientists have developed food coatings that are beneficial to the environment. They have also experimented with a film made of shrimp shells or spider shreds, packaged by milk protein, or edible coating made of pectin. Floor.

Researchers said that the food coating is part of the circular economy and can be extracted in food waste. It is part of the new generation of "intelligent" and "green" food packaging.
