Food preservation is very important. What tips do you know about food preservation?

In daily life, there are many wonderful ways to be the master of life, especially the preservation of food. A little thought can not only be healthy, but also save money. Let's share the methods of food preservation today and learn together.

First, strawberries rot.

The strawberries you just bought will start to rot or mold in a few days. This is because strawberries have high water content, thin skin, easy injury and soft rot.

Strawberries are usually soaked in calcium lactate solution to keep fresh. It is difficult to judge which preservatives are sprayed on the surface, but they are harmless to the human body, but these preservatives are not very durable, and strawberries are facing the fate of rotten tails.

When cleaning strawberries, you can add a few drops of apple vinegar or white vinegar to clear water and gently wipe the surface of strawberries, which can remove most preservatives and keep strawberries stored in the refrigerator fresh and not perishable.

2.bananas are black.

Due to the characteristics of bananas, after a few days of exposure, bananas will grow some "black spots", and many people are afraid to eat them. Banana epidermal cells contain an oxidase. It is tightly wrapped by cell membrane, but once it is squeezed or frozen, the cell membrane will rupture and oxidase will flow out to produce black compounds.

As long as the banana stems are wrapped with plastic wrap to reduce exposure to air and release ethylene, the storage time can be prolonged, and several separate packages are more effective.

3, tea moisture

People who like tea think there is a lot of tea in the cupboard. Some tea leaves that are improperly stored and sealed are prone to moisture deterioration and cannot taste the most primitive aroma.

Tea has the property of "absorbing moisture". Many people expose wet tea to the sun, which will make the tea lose its taste. The best way is to stir-fry tea in a clean pot with slow fire until the steam disappears, and then seal it after cooling, with little loss of tea fragrance.

4. Hard bread

A whole loaf of bread can't be eaten in three or two days, and it is easy to harden after long-term storage. How to solve this problem? The doctor of Master Bang's family suggested that one or two pieces of celery should be put on the bread bag and the mouth of the bag should be sealed. Its moisture content can keep bread moist and fresh at any time, and you can eat soft bread at any time.
