Fresh fruit dries, shrivels and wrinkles easily at home. How to keep fruits fresh?

Preparation materials: starch, egg white, animal oil.

Methods: Pour a small amount of starch, egg white and animal oil into the same bowl and stir well. Prepare a clean watering can and pour the mixed liquid into the watering can. Spray this liquid directly and evenly on the skin of fresh fruit. After spraying, put the fruit in a cool and ventilated place and dry it naturally. The fruit treated in this way can be put into a fresh-keeping bag or directly put into the refrigerator, and it can be kept fresh after eating.

It is suggested that the mixed solution of starch, egg white and animal oil forms a film on the skin of fruit, which can limit the respiration of fruit and keep moisture, thus prolonging the fresh-keeping time of fruit.
