How long does frozen meat at home not be eaten after it is stored in the fridge? What are the effect

If it is stored in the refrigerator or in the refrigerator, if it is stored in the refrigerator for a certain period of time, it must not be taken again. If it has been stored in the refrigerator and there is no special situation such as turning off the power, it can still be taken again, but some of the nutrients may be leaked. Naturally, it depends on the storage time, if it has already been frozen in the freezer.

Three or five years, it is better not to start taking it. As we all know, whether it is germs or bacteria, under normal circumstances, <>

Growth, development and reproduction must all have a certain ambient temperature, but in special circumstances such as ultra-low temperature, the germs will enter dormant mode and will not reproduce, so in other words, after a certain period of storage, the number of germs carried by meat products does not change, but it can be taken again. However, when taking it out, there will be a whole process of thawing, in this case, because the cytoplasm of meat products has already been destroyed by ultra-low temperature, it may lead to the outflow of nutrients when unfrozen, resulting in a significant reduction in the nutritional content of the meat food eaten. It is best to wash the meat and cut it into small pieces and freeze them together in the freezer layer of the refrigerator.

Take it when you want to eat it, <>

If it is kept indoors alone, the temperature may not exceed one day, and the freezing temperature should not exceed three days. Meat products are more susceptible to spoilage. It can be stored for a little longer if frozen.

Try not to freeze for more than six months, the nutritional value of meat within six months will not be lacking, but some harmful bacteria on the frozen meat will be frozen to death, and it will be healthier to eat. According to the relevant national regulations, the maximum shelf life of frozen meat and meat products is one year under minus 18. However, household freezers often open the door, and the ambient temperature is high and low, ensuring that the ambient temperature is not stable, <>

Therefore, the shelf life should be reduced correspondingly, there is no problem with storage for 2 or 3 months, and then the raw pork is refrigerated, which will cause the body fat and protein to be oxidized by the air, and this air oxidation may cause the raw pork to change from the previous dark red to light yellow, so that the metal oxides in it continue to increase, if you take this raw pork, not only the nutritional value of the raw pork will be greatly affected, but also continue to interfere with your health.

Generally, do not store for more than 3 months, after more than 3 months, it is very likely to breed bacteria, it is best not to eat, eating may cause food poisoning, because the protein in the meat will be destroyed, thus destroying our body organs.

Generally, beef can only be stored in the refrigerator for 1 to 2 days, frozen at -18 degrees Celsius can be stored for 3 months, meat steak can be refrigerated for 2 to 3 days, frozen can be stored for about 9 months, chicken can be refrigerated for 2 to 3 days, frozen can be refrigerated for 1 to 2 days, frozen storage time is 3 months to half a year, sausage refrigeration can be stored for 9 days, frozen can be stored for 2 months. Of course, these are not absolute, and are related to the variety of meat stored, the performance of the refrigerator, and the number of times the refrigerator is opened and closed. Eating it can easily cause adverse consequences such as vomiting and diarrhea, fever and even food poisoning.

Generally, when I buy too much meat, I will freeze it in the refrigerator temporarily, but I won't eat it again for more than half a month, because it won't be fresh for too long. Although it tastes meaty, for us, there is not much nutrition left.

Meat that has been frozen in the refrigerator for a year is inedible.

Fan Zhihong, an associate professor at the Department of Nutrition and Food Safety at the College of Food Science and Technology of China Agricultural University, pointed out that if frozen meat is frozen for a long time, there will be a large loss of nutrients. She pointed out that although the loss of nutrients is slower under cold storage conditions than at room temperature, the vitamin content will be lower and lower due to the longer freezing time.

On the other hand, proteins and fats will be oxidized more and more severely, and this oxidation will produce many substances that promote aging, and will make the meat quality worse, the aroma will be slowly lost, and the taste will also change.

Therefore, Fan Zhihong reminds that fresh meat should not be stored in the freezer for more than 3 months, because even at low temperatures, the fat is slowly oxidizing, and the meat that has been frozen for more than one year should not be cooked and eaten.

The storage time of different meats is not quite the same, for example, chicken, goose, duck can not be eaten if it is frozen for more than 10 months, pork and beef can not be eaten if it is frozen for more than 12 months, and mutton can not be frozen for more than 6 months, and fish, shrimp and crab meat can not be eaten if it is frozen for more than 1 month.

The shelf life of frozen meat depends on the type of food, pre-freezing treatment, and freezer temperature conditions, among other things.

The longer the meat is frozen in the refrigerator, the more moisture and nutrients will be lost, and secondly, the taste will deteriorate.

Although freezing meat in the refrigerator is effective in prolonging the shelf life, it is best to consume it within a month.

I think that the meat should be eaten in 3 days in the freshness layer of the refrigerator, and in the frozen layer, it should be eaten within 3 months, and it should be made sure that it has not spoiled before eating.

As people's living standards are getting higher and higher, refrigerators are becoming more and more useful in daily life. Many people buy a variety of foods to store in the refrigerator, but if these foods are not processed in time, it is easy to breed bacteria, and people are prone to various diseases after eating.

1. I think that if the meat is kept fresh, it should be eaten within three days, and if it is left cold, it should be eaten within three months.

There are many people who are busy with work or do not have time to buy groceries, and occasionally when shopping, they will buy a large amount of meat and store it in the refrigerator. Therefore, when we buy a large amount of meat and come back, we need to sort and store it in the refrigerator, so as to ensure that we eat it in good health. Generally, if you want to eat meat within 3 days, you can keep it fresh, so that the taste can be preserved.

Store in a crisper or bag to prevent the growth of bacteria. If there is too much meat to eat in three days, then you should choose a part and put it in the freezer, which can be stored for about three months. If stored for too long, the meat will deteriorate, which will not only taste bad, but also easily cause diseases in the human body.

Second, the fresher the food, the better the taste, and the healthier it is

As we all know, the fresher the food, the better it tastes, the more delicious it is to cook, and the better it is for the body. Therefore, if there is enough time and conditions permit, it is better for us to choose to buy fresh meat every day. The longer the meat is stored in the refrigerator, the more likely it is to breed bacteria, especially spoiled meat, which can lead to cancer if eaten for a long time.

So for the sake of our health, we have to store meat scientifically.

Third, whether the meat that has been stored for too long can be eaten or not, it is necessary to observe whether it has deteriorated

I believe that many people have this feeling, when our meat is stored in the refrigerator for a long time, we will always worry about whether the meat can be eaten, and it is a pity to throw it away. So we can learn some identification skills, take out the meat and thaw it with running water, observe the color of the meat, if it is brighter, it means that it can be eaten, if it is dark, black, yellow, then the meat and spoiled, you can't eat it. Also, you can feel if the meat is elastic, and if not, you can throw it away.

I feel that the meat cannot be eaten in the refrigerator for two days because it will breed a lot of bacteria, and the pork will also have a taste.

Freeze pork in the refrigerator at home for no more than three months, as it will become stale and lose its nutritional value.

Generally, it is stored for about 12 months, but if it is too long, it is easy to breed bacteria, and eating it is not good for the body, so it can only be stored for about 1 year.

Although the state does not have clear regulations on how long the meat can be stored in the refrigerator, it is still necessary to eat the meat for a certain period of time for the sake of their own health and health quality, otherwise the freezing time is too long, and people will be detrimental to their health if they eat it. According to the survey, if it is lean meat, then it cannot be frozen in the refrigerator for more than half a year, fatty meat cannot be more than three months, and seafood cannot be more than one month. Everyone needs to eat frozen meat in the refrigerator according to this schedule, and try not to eat meat beyond this time.

The nutritional value and vitamin content of frozen meat in the refrigerator will decrease, and many of the frozen meat will lose its nutritional value compared to fresh meat, but if you eat it within a week, the nutritional value will not be lost a lot, especially if you eat it within two days, then the nutritional value loss is negligible.

The longer the frozen meat in the refrigerator, the more nutritional value is consumed, so we should try to take out the meat in time to eat, and clean the refrigerator regularly, pay attention to observe whether the food in the refrigerator is deteriorating, if there is deterioration, you must throw it away in time and can not eat it again, otherwise it will affect the body to a certain extent, especially to the human stomach and intestines will cause great damage, and there may be diarrhea and other bad conditions.

Can you eat meat that has been in the fridge for a long time? If it is refrigerated, it will spoil after three days, and if it is frozen, it is not recommended to eat meat that has been in the past six months for more than half a year, and it is not nutritious and will not taste very good.

If it is raw meat in the refrigerator, it can only be stored for three days at most, and after three days, the raw meat will begin to deteriorate and change its taste, and it will not even be edible after a long time. If it is stored in the freezer compartment of the refrigerator, the raw meat will freeze so that it will not spoil and taste. After freezing, raw meat can be left for a long time, a month, a few months, a year, or even longer.

The shelf life of pork in the freezer is generally 4-5 months, not more than half a year, and the freezing temperature is best at minus 15-16. If this period is exceeded, the pork will lose nutrients, the taste will deteriorate, and in addition, a 'psychrophilic bacteria' called listeria will be produced, which is not suitable for consumption.

Frozen food is convenient, however, all frozen foods (including meat) are nutrient lost.

Let's talk about the meat freezing needs to be paid attention to, in order to minimize the loss.

1.Fish: Wet fish must be refrigerated, and fresh fish must be placed in a plastic bag in the freezer compartment of the refrigerator if it is to be left out overnight.

2.Poultry:

Storing poultry meat can multiply harmful bacteria, so if it is to be stored for one to two days, it must be loosely wrapped in wrapping paper and placed in a cool meat storage place: if it is stored for two to four days, it must be stored in the refrigerator.

3.Meat: Fresh meat can be kept for one day in a cool meat storage place and two to three days in the refrigerator. Raw and cooked meat should be stored separately and kept in closed containers to prevent dehydration and odour. Cooked meat must be eaten within a day after being taken out in the refrigerator.

4.Other Food:

Vegetable oil is easy to spoil if it is not left in a cool place, so put a small bottle of oil next to the stove and fill it up in the storage place after use. Dry ingredients such as flour and sugar must be kept in a dry, airtight container, regular flour can be kept for half a year, self-rising flour can be stored for two to three months, and whole wheat flour can be kept for two months.

Before pickling salted eggs, find some pine branches, not too much, ten catties of eggs and half a catty, fresh pine branches are the best, boil them in boiling water for 10 minutes, and pour them into the pickled egg utensils after the water cools. After the eggs are pickled and eaten, this water can still be used to pickle the eggs next time to keep the water clear and not smelly.

In addition, expert studies have confirmed that once frozen foods (such as chicken, duck, fish and various meats) are thawed and stored for a long time, they will quickly cause meat deterioration due to the recovery of bacteria and enzymes, and can also produce toxic substances, and people will suffer from food poisoning when they eat them. For example, if you freeze fresh mackerel for a day at 30 for 6 hours, it will spoil twice as fast as unfrozen fresh fish, which means that by the time you put the thawed fish in the freezer, the fish is most likely spoiled.

The longer the storage time, the lower the nutrition, and the worse the taste, whether the meat can be eaten in the refrigerator for a long time, also depends on the length of preservation, so it is not recommended to eat the meat that has been stored in the refrigerator for a long time, so it is not recommended to eat the meat that has been placed in the refrigerator for a long time, so as to avoid gastrointestinal diseases such as indigestion.

Prolonged storage not only destroys the protein structure of the meat, but also leads to the growth of bacteria leading to diarrhea due to the storage of a variety of foods inside the refrigerator.

Suggestions: It is recommended to deal with meat in a timely manner, it is not recommended to eat, in addition to regularly clean the refrigerator, the food inside the refrigerator is generally not more than 3 days, and the food in the freezer can not exceed 10 days, and a healthy diet is the foundation to ensure good health.

It is recommended not to eat it, because the avian influenza virus can survive in frozen meat for about 300 days, so it is best not to eat poultry meat stored in the refrigerator and freezer for a long time, and do not buy too much at home at one time, so as not to eat it all.
