Fresh-keeping paper that can be kept fresh and eaten recently

Recently, an adhesive film containing natural preservatives can keep foods fresh and eaten in the stomach. This technology was invented by Chinese food experts Zhao Yanyun and Professor Denschel of Oregon State University.

Zhao Yanyun and Denzel collaborated with the researcher Park Soon-yin to mix the ingredients of the crab shell and shrimp shell (chitin) with protein (lysogen) from the protein to make an antibacterial food wrapper. Technology applies for patent rights.

Their next step will be to develop practical applications for their super cling wrap, such as: packing hot dogs, sausages, luncheon meats and other ready-to-eat meats; packaging cheese chips, cheese blocks and cheese sticks; as perishable sliced ​​fruits and vegetables coating.

According to reports, the fresh-keeping substance can also be sprayed on fresh fruit as a liquid, which causes the growth of microorganisms that cause fruit rot to slow down and allows the fruit to be stored for a longer period of time. Vitamins and minerals can even be added to newly invented preservation papers to make food more beneficial to health.
