During the hot summer days, watermelons can be seen everywhere in the supermarket. When you see it, you can't help but buy a few. However, the endless watermelons are covered with cling film and put into the refrigerator. A good way to share it with you today is to use the refrigerator, eat watermelon, and save it for two days.
The correct method of preservation of watermelon
1, only need plastic wrap, or supermarket food bags, then prepare a pot of cold water.
2. Wrap the watermelon with cling film, and then use a toothpick to make small holes in the cling film.
3. Put the wrapped watermelon slowly into cold water (Note: The water cannot exceed the surface of the watermelon). It is no problem to put it in two days. This method of preservation is almost the same as that in the cellar.
When you want to eat again, cut the top layer of watermelon first, so that the taste will be better. However, it is recommended that everyone still eat the watermelon. If you put the refrigerator, it is better not to exceed 24 hours.
Watermelon + cling film = raise bacteria?
In fact, the watermelon covered with cling film may have been contaminated before being placed in the refrigerator. The speed of bacterial growth depends on two factors: the degree of contamination of the food, and the preservation of the food.
Watermelon covered with cling film is prone to bacterial growth. This can't be considered as a problem with cling film. Because a knife that cuts watermelon, a chopping board, or a bag filled with watermelon, it can cause watermelons to have a lot of bacteria before they put it into the refrigerator. Therefore, it is not just a cling film problem.
