What is more lid in the cut watermelon cover?

If you buy the entire watermelon at home, if you can't finish it at a time, it will cover the plastic wrap. However, it is reported that the watermelon covered the plastic wrap has become an environment for bacterial growth. This undoubtedly subverts the cognition of many consumers. Could it be that the practice of preserving watermelon has always been wrong?

Can the plastic wares keep watermelon fresh?

The cling film commonly used in the family is PE film, which is polyethylene plastic plastic wrap. It is a polymer material, which has certain breathability and humidity, which can regulate the oxygen, carbon dioxide and moisture content around the food wrapped, and play a role in keeping food for food. In addition, the surface of the cut watermelon is covered with plastic wrap, which can keep the water well, and can block the dust and bacteria in the environment. When it is stored in the refrigerator, it can also prevent skewers and cross -pollution.

Therefore, it is the right way to store it with plastic wrap after cutting the watermelon.

Bacterial "pot"

Should not be carried by plastic wrap

How much bacteria on the surface of the cut watermelon depends on the cleanliness of the tool, the hygiene of the preservation environment, the preservation temperature, and the time of preservation time, and the food preservation of the food itself does not cause the bacteria to increase.

In fact, whether the plastic wrap or refrigerator refrigerate can prevent the growth of bacteria from growing and reproduction. As long as it is put for too long, the bacteria will still grow in large quantities. Therefore, this "pot" should not be carried by the plastic wrap, which is mainly the scourge of time.

Six small methods are used to keep the campaign

To enable plastic wrap to play a positive effect, it is necessary to use it.

1. To buy regular food -specific plastic wrap.

Food plastic wrap is a "food contact material", and the state has very strict regulations on its security. For non -food preservation film, because it does not directly contact the food, the safety requirements are much lower, which may contain some ingredients that are not good for health. Save food with such plastic wrap is undoubtedly more fresh and more dangerous.

2. The plastic wrap must be strictly covered, so as to achieve the effect of isolation.

3. Do not cover too many layers of plastic wrap, which will cause the breathability to be greatly reduced, which may make watermelon unable to maintain a low -intensity breathing effect, but it is not conducive to freshness.

4. Covering the plastic wrap only to slow down the deterioration to a certain extent, and does not stop the deterioration. Therefore, the food that uses plastic wrap still needs to be eaten as soon as possible.

5. The plastic wrap should not be used for foods with high fat content, which may cause the dissolving and migration of certain ingredients.

6. Try not to heat the food with plastic wrap.
