First, the misunderstanding about fruit storage.
Misunderstanding of fruit storage
1, bananas should be stored at room temperature, can't they be put in the refrigerator?
Wrong. Bananas must be put in the refrigerator when they are ripe. Although the skin will turn black, it will not affect the sweetness of meat. Or you'll attract annoying little fruit flies before you finish.
2. Apples and peaches are put together in the refrigerator?
You can't. Many people are used to putting all the fruits in the fresh-keeping drawer of the refrigerator. If fruits with different characteristics are misplaced, they will start to ripen like peaches in Mama Li's refrigerator.
3, strawberries are washed and refrigerated, and you can eat them when you take them out, which is very convenient.
Wrong. Because moisture can breed germs and microorganisms, which makes strawberries moldy, not only strawberries, but also all fruits. Just wash it before eating.
2. Fruits that need to be refrigerated:
Fruits that need to be refrigerated
Grapes, apples, lotus seeds, guava, strawberries, cherries, pears and oranges. However, the temperature and humidity in the refrigerator are low, and the fruit is easy to lose water. Many people may have experienced it. Some fruits will wrinkle, dry and shrink if they are put into the refrigerator unpacked or refrigerated for too long.
Fruits that are easy to lose water in cold storage environment include pears, lotus plums, guava, cherries, longan and so on.
Avoiding water loss is the key to cold storage. This kind of fruit is afraid of losing water, but it also needs breathing. So you can wrap it in paper and put it in a plastic bag. Plastic bags prevent refrigerators from absorbing water from fruits, while paper helps to absorb water and prevent water from condensing and breeding bacteria and molds. Remember that the mouth of the plastic bag should be slightly knotted, not pricked to death, and ventilated to prevent the fruit from being suffocated.
Cherry is prone to collision and injury, and it is afraid of losing water. It can be packed in a vacuum box to prevent too many cherries from squeezing each other.
Three, the first few days at room temperature and then refrigerated fruit:
Fruits stored at room temperature for several days before refrigeration.
Peach, sweet peach, banana, kiwi fruit, carambola, Sakyamuni, sweet persimmon, avocado, etc. Taking temperature-sensitive fruits such as peaches, sweet peaches and plums as examples, the ideal storage temperature before ripening is 10 ~ 25. 6℃, it must be cooked indoors in the shade in summer, and it can be refrigerated after it softens slightly.
Because the dangerous temperature of peaches and plums is 1. 7 ~ 10℃, the refrigeration temperature of the refrigerator is 4℃, which is in the dangerous temperature range. If peaches and plums are refrigerated before they are fully ripe, they will destroy the fruit tissue and lose water. Fourth, how to judge that the fruit is ripe?
How to judge whether the fruit is ripe?
The maturity of peach, plum, kiwi fruit, Sakyamuni, sweet persimmon and other fruits can be distinguished by hardness. Banana, carambola, avocado and other fruits are judged by their colors, which usually turn from green to yellow before they are mature, while avocado will turn black.
Take the delicate and difficult-to-manage ripe peach as an example. Li Jinyi, who has been doing fruit business for 30 years, shared a small step of skimming fat. After buying it, it needs to be kept at room temperature for about 2 days, and it can be put into the refrigerator for refrigeration if it softens slightly. Before eating, it will be thawed for 2-3 hours, with moderate hardness. However, peaches are also fruits that are afraid of losing moisture in refrigeration. They also need to layer paper and plastic bags to prevent the refrigerator from absorbing water.
In addition, tropical fruits, such as pineapple, banana, mango, papaya and so on. , are also afraid of cold, easy to catch a cold. If they need to be refrigerated after maturity, it is recommended to eat them as soon as possible within two days. 5. Fruits that cannot be put together with other fruits and vegetables:
Fruits that cannot be put together with other fruits and vegetables.
Apple, Sakyamuni, pear, papaya, banana, etc. This fruit releases a gas called ethylene during ripening. Ethylene will accelerate the ripening and aging of fruits. If common vegetables and fruits are put together with this kind of fruit, it is easy to age and rot early.
In the fruit pile, if a fruit is bad, it should be picked out immediately, because the bad fruit will also start to release ethylene, which will make other fruits go bad one by one.
Separate packaging and placement are the key to preservation. This kind of fruit needs to be separated whether it is refrigerated or stored at room temperature. If it is refrigerated, it is recommended to put it in a plastic bag and make a summary at the mouth to avoid the released ethylene affecting the quality of other fruits in the refrigerator. If the fruit is well preserved, you must buy it wisely first.
How to buy good and cheap fruit?
If you don't want to worry about saving fruit, the best way is to buy it in moderation, which can be small and varied, and eat it within one week. Of course, we should also choose the fruits that are abundant in the season, because they are the freshest and the quantity is much cheaper.
Big fruits sell well and are expensive. If you eat it yourself, it is recommended to buy small fruits, which are large in quantity and can be eaten several times. If it is post-ripened fruit, you can choose one that can be eaten on the first ripe day, and the other one that is slightly greener can be left at home for 1-2 days. The fruit is not ripe, but I am eager to eat it. What should I do?
Method of ripening fruit
Of course, there are ways to accelerate fruit ripening, and the trick is to use fruits that release ethylene.
Kiwi fruits and peaches: Kiwi fruits and peaches usually bought back will soften for a few days at room temperature. If you put an apple in a pile of kiwifruit or peaches, it will ripen about 1 day in advance.
Sakyamuni: Sakyamuni can be sprayed with water, wrapped or covered with paper bags or newspapers, which can accelerate the ripening speed, about 1 day. However, the mature and softened Sakyamuni is easy to rot and can be put in the refrigerator for 3-5 days.
