How long can the meat in the cold storage be frozen without spoiling?

Frozen shelf life of all types of ingredients.

Meat (including pork, beef, mutton, bones, etc.) – theoretically 12 months, but try to freeze it for only 3 months.

Meat products (including bacon, sausages, ham sausages) – theoretically 12 months, preferably within 3 months.

Poultry meat (whole and by-products) – Whole can be frozen for up to 12 months, but by-products such as chicken feet and duck necks should not exceed 3 months.

Seafood, fish – up to 1 month. These two ingredients are high in protein, which can be easily broken down and cause a foul smell.

Some people will wonder why the meat at home can only be frozen for 3 months when the meat in the national reserve is rotated every 4 months? The reason is very simple, the "professional cold storage" used for the reserve meat is incomparable to the family refrigerator of several thousand yuan, and the effect of keeping fresh and water is much better.

Pork is the meat we usually eat the most, what should we pay attention to when cryopreservation? The chef teaches you 2 experiences to ensure that the meat is tender and will not spoil within 3 months.

Don't wash the pork, that is, don't get wet; Meat can easily grow bacteria when it gets wet, so don't wash it.

Pork is cut by quantity, sealed in a plastic bag and frozen. Divide according to the amount, only need to thaw a small piece when eating, no waste.

If you don't have the freezing conditions, you can try the "local method", cut the pork into small pieces, boil a pot of soy sauce, pour it into the crisper box, and then put the pork, seal it and put it in a cool and ventilated place, and it can also be stored for 1 month.

First of all, let's talk about the supermarket change like the meat in the plum refrigerator, which is commonly known as refrigerated meat, which is stored at a temperature between 0 and 5, and can generally be stored for 3 to 10 days in the refrigerator.

Then there is frozen meat, this kind of meat is generally stored in cold storage, the temperature is between -18 and -23, and it can generally be stored for half a year to a year, and the lower the temperature, the longer the storage time. Correspondingly, the lower the temperature, the higher the cost of the cold, not only the cost of building the cold, but also the maintenance cost.

At this time, some people will say that it is not so easy to distinguish whether the meat has deteriorated after it is frozen hard, and what if there is an unscrupulous merchant who takes out the "zombie meat" that has been stored for a long time and sells it?

In fact, you don't have to worry too much, because meat is very strict about frozen eyeballs, and the cost of storage is very high. Due to the cost problem, the meat is stored for a long time, and even if it is sold, it may not be enough to pay for equipment.

At present, the maximum storage period of frozen meat is 1 to 2 years, and the maximum storage period of aquatic products is 7 to 8 months.

Therefore, if you buy frozen meat to eat, it is best to eat it as soon as possible and not store it for too long.

At present, the maximum storage period of frozen meat is generally one to two years.

China began to build cold storage as early as the fifties and sixties of the last century, and by the nineties of the last century, the country has built 10,000 tons of cold storage. Zhou Tong, general manager of the farmers' market, told reporters: "Before 2000, the cold storage rental ** was only 1 to 2 yuan per square meter per day, and so far it has nearly doubled.

In recent years, China's cold storage construction has developed very rapidly, mainly distributed in the fruits and vegetables, aquatic products, animal husbandry production areas and the suburbs of large and medium-sized cities planting and breeding bases, the longest storage period of frozen meat is generally one to two years, and the storage period of aquatic products is up to seven to eight months.

Frozen meat can generally be kept in the freezer for six to 12 months, and there is no problem with six-month meat, and after a long time, the nutrients will be lost.

Hello, glad to come to your questions. Generally frozen meat. Do not exceed six months. After more than six months, the meat will lose a lot of nutrients.

So it's the longest time. It's best to keep it for six months.

Frozen meat is best not older than 12 months. Bacteria can also grow at low temperatures.

It is recommended to throw it away and not to eat it, according to the national standard for the freezing time of frozen meat, it is recommended to keep it for a maximum of one year, but there are conditions for this year, generally speaking, if the meat is stored at minus 18 degrees, it can be left for up to 1 year, but not more than 1 year. However, we usually freeze meat at home. If the refrigerator cannot reach minus 18 degrees, then the meat cannot be stored for more than half a year.

Even if there is no smell for more than half a year, you can't eat it. Ordinary seafood should not last more than 6 months even at minus 18 degrees Celsius. If it is exceeded, even if it is wasted, don't eat it, eating it is not good for your health.

How do you defrost meat from the fridge?

The first method: add salt to thaw. Salt can greatly speed up the defrosting process, put the salt in cold water and then add salt, it will not take long for the meat to thaw successfully, or you can also apply salt to the surface of the meat.

The second method: add vinegar to thaw, but in fact, when defrosting frozen meat, adding vinegar is also a good way to get a quick thawing effect.

The third method: put the meat between two aluminum basins, and pour hot water into the aluminum basin above, so as to quickly thaw the meat, which mainly uses the principle of good thermal conductivity of aluminum products, so you can try it at home.

Using the above three methods to thaw meat can greatly shorten the thawing time, while maintaining the tender taste of the meat without affecting the meat quality. It's just that eating meat that has been frozen for a long time is not particularly good, and it is better to buy fresh meat every day.

Frozen meat in the refrigerator can be stored for two months.

The "psychrophiles" that live in refrigerators can grow in an environment of 0 20 and are found in everyday foods such as meat products, dairy products, vegetables, salads and seafood.

Precautions for frozen meat.

The "psychrophiles" that live in the refrigerator can grow in an environment of 0 20, and the most common psychrophilic bacteria are Hyyers and Listeria. Listeria monocytogenes is an intracellular parasite found in everyday foods such as meat products, dairy products, vegetables, salads and seafood. It can survive at a temperature of 2 5 42, reproduce the fastest at 4 6 hours, and can grow and reproduce for a long time in the refrigerator room under the household refrigerator.

In addition, some fungi and molds can also cause cross-contamination and spoilage of food in the refrigerator. The refrigerator compartment should be cleaned and disinfected regularly, especially in summer, preferably once a week. In addition, hot food should be cooled before being stored in the refrigerator to minimise moisture in the box and avoid mold on the inside of the refrigerator.

One week. Fresh meat can be frozen in the refrigerator for 3 months, the refrigerator has a freezer compartment, the temperature in the freezer is constant at -18, the meat placed in this layer will also be frozen, the frozen meat in the refrigerator can only be stored for 3 months, and it will be rancid and spoiled if the time is too long.

As the storage time is extended, the nutrients of the pork will be lost, and the taste will deteriorate, and during the storage process, a psychrophilic bacterium called Listeria monocytogenes will be produced, which is not suitable for consumption if it is frozen for too long. And opening the refrigerator frequently during the freezing process has an impact on the shelf life of the meat.

Extended Information: Precautions for Eating Meat:

1. The cooking time of the meat can not be too long, some people like to eat soft and glutinous meat, so they will cook the meat in the pressure cooker for a long time, even the bones are soft, at a temperature of 200 300, some substances in the meat food will react to produce aromatic amines, which can cause cancer.

2. Frying cured meat is also not good, meat after cooking in this way, nitrosoarsenic rolidine will be produced, which is a carcinogen, so when eating salted fish, salted meat, fragrant mold intestines, ham and other foods, you must not fry, when cooking pickled food, you can add some rice vinegar, because vinegar has the effect of decomposing nitrite, and can sterilize.

How long the meat can be stored at room temperature depends on the temperature and season. If it is summer, and the raw meat that has not been processed is stored at room temperature, then spoilage will occur after one day of storage. In winter, the time is a little longer, and it can be stored for about 2 to 3 days.

In spring and autumn, it can only be stored for about 2 days.

If you don't plan to eat fresh pork for two days, you should wash it to wash off the blood on it, then wrap it in liquid retention film and put it in the refrigerator for freezing. Fresh meat can be stored in the refrigerator for 3 months, because the temperature in the freezer is constant at -18, and the meat placed in this layer will be frozen, which can prevent the raw meat from breeding bacteria, and it will be stored for a longer time.

Raw pork can be stored for a long time when it is frozen in the refrigerator, but as it is stored for a longer time, the nutrients of the meat will be lost and the taste will deteriorate. Therefore, it is not recommended to continue to eat raw meat that has been stored for too long.

Fresh raw meat is best eaten within a week, and should not be kept for a maximum of two weeks. Raw meat may not spoil in the short term when it is frozen in the refrigerator, but the freshness will become less and less fresh over time, and even a foul smell will appear. Also, during storage, opening the refrigerator frequently has an impact on the shelf life of the meat.

Hello, the result has been found for you: the time it takes for frozen meat to be refrozen depends on a number of factors, including the type of meat, storage conditions and freezing time. In general, if the frozen meat is not contaminated or spoiled in any way during the tease freezing process, the time to refreeze it can be extended by at least 1 month.

However, it is best not to freeze and thaw meat repeatedly, as this will affect its quality and taste. In addition, frozen meat should be completely thawed when thawed to avoid partial thawing and then re-freezing, which will cause the meat to lose moisture and cause a worse taste of the meat. I hope the results of my query can help you.
