The birth of the refrigerator has facilitated the lives of housewives. They can buy a lot of food at once instead of going to the vegetable market every day, and they don’t have to calculate how much food to make every day. But the refrigerator is not a panacea, not all food can be stored in it for a long time. Most tropical fruits are afraid of cold and should not be kept in the refrigerator. Frostbitten fruits are not only damaged in nutrients, but also easily spoiled. In a few days, the pulp will rot.

And when bananas and mangoes are stored at a temperature of 10℃, the peel will turn black; when pineapples are stored at 6℃-10℃, not only the peel will change color, but also the flesh will be water-soaked; lychees, longan, rambutan, etc. When stored at 1 ℃-2 ℃, the color of the exocarp will darken, and the endocarp will have spots like burns.
