In hot summer, many people like to keep the cut watermelon in the refrigerator, so that they can eat delicious frozen watermelon, and also cover the watermelon with a layer of preservative film, but sometimes the preservative film can not make the watermelon very fresh, so it is not recommended to stick the preservative film!
Do you want to seal the preservative film when putting watermelon in the refrigerator? Generally, it is not recommended to stick the preservative film. Many people think that it's better to keep food fresh by putting plastic film on the refrigerator. But that's not all. Experts say watermelons preserved with plastic wrap will get worse faster than those without plastic wrap. (this article is exclusively compiled by WYH, editor of sihai.com.

Because there are bacteria and microorganisms on the surface of watermelon before the fresh-keeping film is sealed, if the permeability of fresh-keeping film is not good and the temperature drops slowly, the bacteria will propagate faster, especially the food will easily deteriorate after the anaerobic reaction. Moreover, if the film is too thick, not only the moisture is not volatile, but also the carbon dioxide in it cannot be discharged, which is not conducive to preservation. If the film is too thick, the food will not be able to 'breathe' to oxygen, which will lead to anaerobic fermentation and decay. Therefore, if you haven't finished eating watermelon, it's not recommended to stick plastic wrap in the refrigerator.
Of course, for refrigerators with mixed food, if there is a huge source of pollution, such as raw materials that have not been cleaned, it will also cause pollution without fresh-keeping film. Moreover, watermelon without preservative film is easy to cross taste. Therefore, the healthiest way is to eat in the shortest time. In addition, when the watermelon in the refrigerator is taken out for eating, the part about 1cm on the surface can be cut off first.

How to keep the cut watermelon fresh?
After cutting, the watermelon can only be stored for a short time. Wrap it with plastic wrap and put it in the refrigerator. If there is no refrigerator, wrap it in the fruit tray with some water. However, stick a thin plastic film or refrigerate the watermelon directly in the refrigerator for up to 24 hours. In addition, when the sealed watermelon in the refrigerator is taken out for eating, it is recommended to cut off the part about 1cm on the surface first.
