Every household has a refrigerator, and the refrigerator is a common one we useKitchen utensils,It is used to preserve ingredients. Fruits or leftovers that you can't eat at home can be extended by storing them in the refrigeratorWarrantyTime limit.

What aspects should be paid attention to when storing vegetables at home
Vegetables contain a lot of vitamins, and improper preservation before consumption can cause vitamin loss, of which the most lost is vitamin C, followed by vitamin B2. Vitamins are easily destroyed by oxidation in the air at room temperature, and the destruction of vitamins can be delayed by preserving the outer leaves and shells.
Therefore, do not peel off the outer leaves of bulbous vegetables, do not peel off the outer skin of onions and garlic, and do not peel off the pods of beans before eating. Potatoes need to be kept away from light to prevent the sprouts and rind from turning green to produce toxic solanine.
The nitrite content in fresh vegetables is very low, and if it is stored for too long, the nitrite content will increase significantly when it decays and deteriorates. If stored in the refrigerator at low temperature, the respiration intensity of vegetables is relatively weak, not easy to rot, and the contents of vitamin C, total sugar and nitrite do not change much.
Therefore, refrigeration is more conducive to the preservation of vegetables and nutrients than room temperature storage. But it is not a good idea to put all the vegetables in the refrigerator, and different vegetables should be sorted and kept fresh.
Scientific preservation methods for different vegetables
Winter melon: Winter melon with intact skin and complete hoarfrost should be selected, spread a wooden board in a ventilated and cool place, and put the winter melon on it, which can be kept fresh for 4 to 5 months.
Winter bamboo shoots and ginger: Find a container and spread wet sand, bury the winter bamboo shoots and ginger with the tip facing up in the sand and pat it firmly, and place it in a dark and ventilated place to keep it fresh for 4 to 7 weeks.
Onions and garlic sprouts: Dry onions or garlic sprouts, put them in a cool, dry and ventilated place, they can be stored for a long time, and they should not be wrapped in plastic bags or put in the refrigerator, so that the onions or garlic sprouts will be stuffy, spoiled and sprouted.
Potatoes: It should be refrigerated at low temperature, not at high temperature, otherwise the starch content of potatoes will be reduced and they will sprout. In addition to keeping them at low temperatures, keep the potatoes dry to prevent mildew.
Garlic: Put the good garlic in a plastic bag and seal it tightly, put it indoors, check it once a week, and take out the shriveled garlic in time if it is found.
When keeping fresh, all kinds of small plastic packaging bags have different colors, and it is very easy to mess up in the refrigerator. Therefore, it is uniformly packed into a white storage basket, and it is also placed vertically inside, which is easy to find.

In order to prevent cross-smelling, we are generally used to wrap a layer of plastic wrap before putting it in the refrigerator to keep it fresh. But plastic wrap actually has many disadvantages, such as difficult to tear, every time you have to find scissors, tear it off with its own serrations, the plastic wrap bounces back and sticks together under the force, and you have to uncover it by hand, which wastes a lot of time and is particularly troublesome.
