Fruit preservation tips
Many fruits release a lot of ethylene in the process of ripening, such as apples, bananas, papayas and so on. If they are placed together with other fruits, they will accelerate the ripening of other fruits, and then they are prone to rot. There are also broken fruits, which also release a lot of ethylene, which need to be taken out of the pile immediately to avoid contact with other fruits.
Dont wash off the pectin:
The surface of fruit is protected by natural pectin, which can prevent water loss and microbial invasion. If the fruit is stored in the refrigerator, it does not need to be cleaned before putting it in the refrigerator, because the pectin is easy to be cleaned out during the cleaning process. Store the fruits by category, and put the fruits that are easy to be damaged into the fresh-keeping box to avoid being squeezed in the refrigerator.
Fruits like mangosteen, grapes and raisins are easy to oxidize and rot. Therefore, in the preservation of this kind of fruit, not only need cold storage, but also try to exhaust the oxygen, so as not to oxidize the fruit. After putting the mangosteen, grape, raisin and other fruits into the fresh-keeping bag, pay attention to gently press the air inside to discharge, and then put it into the refrigerator for refrigeration. It is also necessary to take care to pick out the damaged fruits and discard them, so as not to affect other intact fruits.
