Fresh eggs: frozen for 30~60 days, cooked eggs: frozen for 6~7 days, milk: frozen for 5~6 days, yogurt: frozen for 7~ 10 days, fish: frozen for 1~2 days, frozen for 90~ 180 days, and beef: frozen/. Frozen canned food for 360 days: peanut butter and sesame sauce for 360 days: canned coffee for 90 days: canned apple 14 days: citrus for 7~ 12 days: pear for 7 days: cooked tomato 1~2 days: spinach for 3~5 days.
Question 2: How long can frozen meat be kept? Low temperature storage, that is, cold storage of meat, is the most practical method for the storage of meat and meat products. At low temperature, especially when the temperature drops below-10℃, the water in the meat turns into ice, resulting in an environment where bacteria cannot grow and develop. However, when the meat was thawed and recovered, the bacteria began to grow and reproduce again due to the increase of temperature and the exudation of gravy. Therefore, when meat is stored at low temperature, it must be kept at a certain low temperature until it is eaten or processed, otherwise the quality of meat cannot be guaranteed. The cold storage of meat can be divided into chilled meat and frozen meat.
1. chilled meat: it is mainly used for meat stored for a short time, and the central temperature of meat is usually reduced to about 0℃ ~ 1℃. The specific requirement is that the temperature of meat should be reduced to about minus 4℃ before it is put into cold storage, and kept between-1℃ ~ 0℃ after it is put into storage. The cooling time of pork is 24 hours and it can be stored for 5 ~ 7 days. After cooling, a dry film is formed on the surface of the meat, which prevents the growth of bacteria, slows down the evaporation of water and prolongs the storage time.
2. Frozen meat: the meat is quickly and deeply frozen, so that most of the water in the meat is frozen into ice. This kind of meat is called frozen meat Frozen meat is more storable than frozen meat. Meat is usually frozen at a temperature below -23℃ and stored at about-65438 08℃. In order to improve the quality of frozen meat and restore the original taste and nutritional value after thawing, most cold storages adopt quick freezing method at present, that is, the meat is put into a quick freezing room at -40℃, so that the meat temperature can be quickly reduced to below-18℃ before moving into the cold storage.
Question 3: How long can meat be refrigerated? This is also related to the season. Fresh meat is put into the freezer for half a month in summer and half a month in winter.
Question 4: How long can meat be kept in the refrigerator for no more than 3 days, otherwise it will obviously go bad.
Question 5: How long can pork be kept in the refrigerator? A. the indoor temperature of the freezer is about-18℃. It can store fresh or frozen meat, fish, poultry and cooked food for about 3 months. This room can quickly freeze fresh fish foods that need to be preserved for a long time to ensure the fresh flavor of the food to the maximum extent.
B, the temperature of the cold room is about 5℃, raw and cooked foods can be refrigerated, and the storage period is about one week. Fruits and vegetables should be stored in fruit and vegetable boxes (the temperature is 8℃) and packaged with plastic wrap. C. The ice temperature fresh-keeping room is located at the upper part of the cold storage, with a temperature of about 0℃. It can store fresh meat, fish, shellfish, dairy products and other foods. It can be kept fresh without freezing, and can be used at any time. The storage period is about three days. The ice temperature fresh-keeping room can also be used as a thawing room for frozen food. If you put food in your room before going to work, you can use it immediately after work.
Of course.
The key to preservation-the eggs you buy must be kept in the refrigerator, which is well known. But put it with the big head up and the small head down. I'm afraid you don't know, do you This can not only prevent microorganisms from invading the yolk, but also help to ensure the quality of eggs.
Question 6: How long can meat be frozen in the refrigerator, and it can't be eaten for about two months at MINUS 20 degrees? No problem. It is not recommended to use it for too long! Nutrients are easy to lose.
Question 7: How long can frozen meat be kept? Theoretically, frozen meat can be preserved all the time, and its quality will not change. But the longer it is stored, the more water will be lost. Although the meat can be rehydrated when eaten, it still tastes a little different, but it tastes a little different.
However, the time for storing meat at home will not be too long, and it is impossible to reach several years, so it can be safely stored and will not change. At present, the refrigerator can generally maintain the temperature of MINUS 18 degrees, and it is no problem to keep it for one year. It is recommended to eat within 3 months.
Question 8: How long can meat be frozen in the refrigerator? There is a timetable for keeping food fresh in the refrigerator.
The common cold storage temperature of food in the refrigerator is 4℃ to 8℃. In this environment, the growth rate of most bacteria will slow down. But some bacteria are psychrophilic, such as Yersinia, Listeria, etc., which can grow and reproduce rapidly at this temperature. If you eat food infected with this kind of bacteria, it will cause intestinal diseases. The temperature in the freezer of the refrigerator is generally around-18℃. At this temperature, bacteria are generally inhibited or killed, so the food stored in it has better fresh-keeping effect. But freezing does not mean that it can be completely sterilized, and some bacteria with strong freezing resistance will survive. Therefore, from another perspective, if the refrigerator is not disinfected frequently, it will become a "hotbed" for some bacteria.
How to use the refrigerator correctly is also an indispensable family knowledge for housewives. For the sake of family health, it is necessary to know how long the food in the refrigerator can be kept. The following is the timetable for storing food in the refrigerator.

Everyone has a refrigerator and everyone can use it, but some precautions may not be known to everyone.
There are six taboos for storing and freezing food:
Hot food should never be put in a running refrigerator.
Store food should not be too full or too tight, and leave a gap to facilitate cold air convection, reduce the load of the unit, prolong the service life and save electricity.
Food should not be mixed raw and cooked to maintain hygiene. According to the requirements of food storage time and temperature, the space in the box is reasonably utilized. Don't put the food directly on the surface of the evaporator, but put it in a vessel to avoid freezing on the evaporator, which is inconvenient to take out.
Fresh fish, meat and other foods can't be put into the refrigerator without treatment. Fresh fish and meat should be packed in plastic bags and then stored in the refrigerator. Vegetables and fruits should be dried on the outer surface, placed at the bottom of the box and stored at zero temperature.
Bottled liquid drinks should not be put into the freezer to avoid freezing and cracking the packaging bottles. It should be stored in the refrigerator or on the door, preferably at around 4℃.
Refrigerators that store food should not store chemicals at the same time.
Attention should be paid when storing the following foods:
Banana: Banana will turn black and rot when stored below 12℃.
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 being frozen at low temperature, the flesh of tomatoes is blistered, soft and rotten, or cracked, with dark spots on the surface, immature and tasteless, and in severe cases, it is rancid and rotten.
Ham: If ham is stored in the refrigerator at low temperature, the water in it will freeze, the fat will precipitate, the leg meat will agglomerate or loosen, and the meat will become stale and perishable.
Chocolate: once the chocolate is refrigerated in the refrigerator, once it is taken out, it will form a layer of frost on its surface at room temperature, which is easy to go moldy and deteriorate and lose its original flavor.
1, hot food must not be put into the running refrigerator.
2. The food should not be too full or too tight, and there should be a gap to facilitate cold air convection, reduce the load of the unit, prolong the service life and save electricity.
