Don't put the first one in the refrigerator, or you will get frostbite. Such as banana, carambola and loquat.
The second kind can be put in the refrigerator, but it must be ripened first (that is, unripe fruits can't be put in the refrigerator). Such as durian, mango, Sakyamuni, passion fruit, persimmon, papaya and so on.
The third category must be kept in the refrigerator for a long time. Such as: peach, mulberry, plum, litchi, longan, rambutan, cherry, chestnut, guava, grape, pear, strawberry, mangosteen, pitaya, melon, grapefruit and so on.
The fourth category can be stored at room temperature or refrigerated in the refrigerator. Such as: lemon, pineapple, grape, orange, olive, jujube, apple, watermelon, orange, coconut, grapefruit, sugarcane and so on.
Bananas are tropical fruits, and the suitable storage temperature is about 65438 02℃, while the temperature in the refrigerator is generally 0-4℃. Therefore, if bananas are put in the refrigerator, it is easy to cause chilling injury, reduce nutrition and even cause rot.
Fresh litchi: When fresh litchi is left at 0℃ for one day, the peel will turn black and the pulp will turn sour.
Tomatoes: After low-temperature freezing, the flesh of tomatoes bubbles, appears soft and rotten, or peels off, with dark spots on the surface, immature and tasteless, and in severe cases it is rancid and rotten.
Which fruits are kept in the refrigerator?
1. "Cooked" fruits refer to fruits that are ripe at the time of harvesting, mainly including grapes, apples, strawberries, cherries, pears, oranges and so on. If this fruit is placed directly at room temperature, it will be overcooked and rot quickly; It is easy to lose water directly in the refrigerator. The best way is to wrap it in paper first, then put it in a bag and put it in the refrigerator. This can not only prevent the refrigerator from absorbing water from fruits, but also prevent water vapor from condensing and breeding bacteria and molds.
2. "After-ripening" fruits "After-ripening" fruits are not fully ripe at the time of harvesting, and they must be kept at room temperature for a period of time before they can continue to mature, mainly including peaches, plums, bananas, kiwis and persimmons. Take peaches, plums and other fruits that are sensitive to temperature as an example. The ideal storage temperature before ripening is 10-25℃. In summer, it should be ripened indoors in the shade, and it can be refrigerated after softening slightly. If refrigerated before full maturity, it will destroy the fruit tissue and lose water. Whether peaches, plums, kiwis, sweet persimmons and other fruits are ripe or not can be distinguished according to their hardness. Generally, it can be stored at room temperature for about 2 days after being bought, and it can be put into the refrigerator for refrigeration when it softens slightly. Tropical fruits, such as pineapple, banana, mango, papaya, etc. Afraid of cold, it should be refrigerated after maturity. It is recommended not to exceed two days.
Special reminder: apples, pears, papaya, bananas, etc. Can't put it with vegetables. Some fruits can't be put together with other fruits and vegetables, such as apples, pears, papaya, bananas and so on. This kind of fruit will release "ethylene" gas during the ripening process, which will accelerate the ripening and aging of the fruit. If other fruits and vegetables are put together with this fruit, it is easy to age and rot early. Bad fruit also releases ethylene, so if one fruit in a pile is bad, it should be picked out immediately.
Refrigerators are generally set to a constant temperature, but in fact different fruits and vegetables have different fresh-keeping temperatures. For example, 1℃-3℃ is the best storage temperature for apples and pears; The fresh-keeping temperature of tropical fruits such as banana, litchi and mango is about 8℃- 12℃. If fresh litchi is stored at 0℃ for 1 day, the peel will turn black and the pulp will turn sour.
Different fruits have different preservation methods. For example: litchi, wrapped in paper, put in plastic bags, and then put in the refrigerator for four or five days; Bananas shouldn't be put in the refrigerator. It's best to choose a slightly raw banana. When eating, put bananas and apples in a bag and tie the mouth of the bag tightly. Bananas will ripen quickly within a few hours. Strawberries should be kept fresh, neatly placed in cans, sealed with plastic film and placed in a cool and ventilated place for a week; Peaches should only be stored at low temperature, the refrigeration temperature is -0.5-0℃, but the refrigeration time should not be too long, otherwise the fruit will be dull and tasteless; Kiwifruit is suitable for storage in the refrigerator at -0.5-0℃, but it can't be put together with apples and pears, which will accelerate the ripening and decay of pulp; Watermelon with smooth surface can be selected, soaked in salt water with a concentration of about 10% for about 15 minutes, sealed with plastic bags and placed in a cool place, which can prolong the shelf life. In summer, the temperature is usually higher and the air humidity is higher! In this case, fruits, vegetables, food, etc. are easy to rot and deteriorate if they are not well preserved! In view of this phenomenon, the countermeasures mainly include the following points:
First, put some ice cubes next to the fruit to cool down and keep fresh.
Second, don't pile the fruit too high, pay attention to ventilation.
Third, the surface of the fruit should not be sealed too tightly, but the surface must be covered with a used filter screen to prevent mosquitoes and flies. Fourth, use a fan to blow the fruit for cooling and ventilation to prevent fruit rot and mosquito bites.
