Is food in the freezer stored for a long time?

The sooner you eat raw meat in the freezer, the better, the longer it lasts, the more it will affect the taste of the freezer, and it will also breed bacteria;

It is best not to refrigerate meat for a week, and it is best not to freeze for more than three months.

Store meat products properly.

If you plan to eat the meat you bought in a few days, you can put it in the cooler part of the refrigerator; If it is intended for long-term storage, it should be placed in the freezer compartment of the refrigerator.

For fresh meat, the whole meat can be pre-divided into small pieces and served in a grocery box with a lid or in a double (two) plastic plastic bag. This is not only convenient to eat, you can take a few packets as needed, without affecting others, but also can improve the freezing speed of the meat and ensure that the meat quality is good.

In order to maintain the original freshness and taste of meat products and prolong the storage period, it is necessary to take quick freezing. In the quick-freezing process, the ice crystals formed in meat products are very small, and the intracellular fluid, extracellular fluid and intercellular crystals of the tissue will not flow out. Some refrigerator users, the freezing method is wrong, so that the meat food forms large ice crystals, destroys the cell membrane of the food, causes the cell rupture, and the tissue nutrients and freshness are lost with the water after thawing, making the food loose and the umami taste is greatly reduced. The correct freezing method is to first adjust the knob of the temperature controller to the coldest gear, so that the compressor keeps freezing quickly, and after about 30 minutes, then put the knob of the plague controller on the gear of the usual required temperature, so as to ensure the original freshness and taste of the food.

It is best to take out the quick-frozen meat food from the freezer the day before cooking, and thaw it slowly in the refrigerated room (6--8), the juice ice crystals between the meat cells and the cells gradually dissolve and penetrate into the cells, restore the state of fresh meat, and the taste is no different from fresh meat when cooking. Some people are anxious and put the quick-frozen meat in a pot to boil or boil water in order to thaw it quickly. I don't know that in this way, the meat cells and meat fibers form a frozen gravy, which suddenly dissolves into a liquid and flows out of the meat tissue, which not only loses a lot of nutrients, but also makes the cooked meat not tender and smooth, old and boring.

Many microorganisms can still survive at low temperatures, so they should not be stored for too long. Generally, livestock meat can be stored for 3 7 days in 1 --1, and can be stored for a longer time in -10 --18, usually 1 2 months. It is recommended that the temperature of the refrigerator room should not be lower than 4, and the temperature of the freezer should not be lower.

Aged goods stored in the refrigerator can produce enzymes, bacteria and nitrosamines, which may cause cancer. Therefore, meat should not be stored in the freezer for more than 3 months, and fish should be stored for a shorter time.

It is necessary to arrange the food in the refrigerator reasonably, not to mix raw and cooked together, not too full, to ventilate, cooked food on the top, raw food on the bottom. Even if the meat is cooked and taken out of the refrigerator for reprocessing, it should not be simply heated up, regardless of whether the original packaging is intact or not, it should be fully cooked and cooked thoroughly.

What kind of food is the score, and some foods are not suitable for the refrigerator, such as starchy foods.

Starchy foods such as steamed buns, flower rolls, and bread should not be put in the refrigerator, which will speed up the speed at which they dry and harden. If you can't eat it for a short time, you can seal it and put it in the freezer to freeze it.

In addition, bread and biscuits should not be stored together. In this way, the moisture in the bread will be transferred to the biscuit, making the biscuit soft and the bread harder, which is not good for both; Fish.

Fish in the refrigerator should not be stored for too long. The refrigeration temperature of household refrigerators is generally -15, and the best refrigerator can only reach -20.

Aquatic products, especially fish, will be dehydrated or other changes in the body tissues when the storage temperature does not reach below -30. If the crucian carp is refrigerated for a long time, it is easy to have rancidity and changes in meat quality, making it inedible; Tomato.

After the tomatoes are frozen at low temperature, the flesh is blister-like, soft and rotten, or there is a phenomenon of spallation, there are black spots on the surface, it is undercooked, there is no umami, and in serious cases, it is rotten; Leafy greens.

When leafy greens are kept in the refrigerator, not only will the leaves spoil faster, but they may also produce toxic nitrites due to the action of enzymes and bacteria. I saw all of these in the topic of Baby Xiuxiu, and the knowledge in it is relatively comprehensive.

Generally, it doesn't take too long, and some bacteria will still grow.

Some things are okay, some things can't be written, but it's not good to put them long.

Don't leave anything in the fridge for a long time anyway.

It depends on what it is.

1. If the freezer is not used for a long time, unplug the power first, take out all the food after the dust, and clean the inside of the freezer to avoid breeding bacteria.

2. Wipe the position of the seal with a rag and then apply talcum powder for maintenance. Filial piety lead.

3. Finally, place the freezer in a dry and ventilated place away from the heat source, pay attention to the fact that no items can be placed on the top of the freezer, and ensure that the bottom of the refrigerator is placed smoothly.

Storage method and precautions:

1. Turn off the power to the freezer and take out the ice.

All items stored in the cabinet;

2. Open the freezer door and remove it.

Plug the drain hole at the bottom of the plate.

Right, after all the frost in the freezer has completely melted into water and drained clean, wipe off the residual water with a clean towel;

3. Plug the drainage hole on the upper back, keep it open and thoroughly dry the moisture inside the freezer;

4. Place the freezer in a dry and ventilated place, and cover the freezer with a plastic cover to prevent the electrical components of the freezer from being damaged by moisture and the dust on the surface of the freezer due to excessive humidity for a long time;

5. During the storage period of the freezer, it is best to open the cabinet door regularly and check whether there are signs of mold inside, and if there is, clean the internal surface of the freezer again;

6. If conditions permit, you can open the cover plate on the side of the freezer and the periphery of the radiator to properly clean the dust and debris in the compressor part of the freezer, and do not touch or damage the pipes and accessories of the freezer refrigeration system during the cleaning process.

Some come to the family in winter when there is a natural cold storage (balcony.

bai), refrigerators are rarely du

I used it. What to do if the refrigerator is not in use, you are afraid that it will be idle, and now I will teach you how to maintain the refrigerator when it is not in use.

Unused refrigerators should pay attention to the following:

1. Unplug the refrigerator and get everything out of the refrigerator. Open the refrigerator door and wait for the frost to melt, defrost please do not use sharp tools, the evaporator is made of aluminum, which is easy to puncture. Then use a clean cloth to wipe the refrigerator clean from the inside out.

There must be no water.

2. When the refrigerator is not in use, the door seal should be padded with paper or other things to prevent the door seal from sticking to the box; If you are going to not use it for a long time, just apply some lime powder to the door seal.

3. Set the thermostat adjustment to "0" or "stop" or "max" (strong cold point) to make the thermostat elastic in a natural state and prolong its service life.

4. When moving the refrigerator, please stand upright and move in parallel, do not tilt, to prevent the compressor from falling out of the cylinder. Store in a ventilated and dry place away from direct sunlight.

5. Because the refrigerant freezing point of the refrigerator is very low, there is no need to worry about it freezing, and it is better to put the refrigerator in a place with a higher temperature.

6. If there is a condition, it is best to turn on the electricity once a month, so that the compressor can run normally for half an hour to an hour and then shut down to preheat the compressor.

Wash it well, disconnect it from the power supply, and be sure to put the fluorine clean and wrap it all in a large plastic bag.
