It is suggested to buy some vegetables and store them. Among them, green leafy vegetables only need to be purchased for 3 days, because if the storage time is too long, the quality will be seriously reduced. Green leafy vegetables must be wrapped and put in the refrigerator, but be careful not to get close to the inner wall of the refrigerator to avoid frostbite. Beans, eggplant, tomatoes, green peppers and cucumbers can be stored at low temperature for 4-5 days, while potatoes, carrots, onions, radishes and cabbages can be stored for longer. If there is no room in the refrigerator, wrap it in soft paper, then put it in a plastic fresh-keeping bag on the balcony or in a cool place where it won't freeze.
There is usually no shortage of all kinds of fish in festivals. Except for the amount of New Year's Eve dinner, the other amount is about two or three days. There may be some braised pork or bacon sausages in this part. Braised pork with sauce can be kept in a fresh-keeping box for two or three days, while bacon sausages can be kept in a dry and cool place outside the refrigerator. Fish and raw meat need to be packaged in advance into disposable quantities and then put into the freezer. It should be noted that raw meat, cooked food and vegetables must be stored separately, not on the first floor, drawers or fresh-keeping boxes. Seafood and livestock meat should be separated as much as possible, and should not be put in fresh-keeping bags.
Fruits only need to be prepared for 3-5 days, and a small part of them are varieties that can only be stored at room temperature for one or two days, such as strawberries and grapes. Most of them can choose apples and oranges that can be stored at room temperature for more than a week. Tropical fruits such as bananas and mangoes should be kept in a cool place at room temperature, not in the refrigerator. When thawing, take the fish out one night in advance and put it in the cold room, which not only avoids nutrient loss, but also avoids uneven thawing and saves energy.
