Generally speaking, the frozen insurance period of meat food is 3 months, the frozen insurance period of seafood food is 1 month, and the shelf life of frozen foods such as jiaozi and steamed bread is 6 months!
Don't thaw and freeze meat repeatedly. The meat you just bought can be cut into small portions according to the amount you eat each time, and then packaged separately and frozen. Should not be frozen for too long, it will cause the loss of food nutrition!
If it is stored in the refrigerator, should it be put in the freezer or in the freezer? If you keep it in the refrigerator for a while, you can't eat it any more.
If it is frozen under special circumstances such as no power failure, it can still be eaten, but some nutrients may be lost. Of course, it depends on the storage time. If you freeze in the refrigerator for three or five years, you'd better not eat any more.
As we all know, under normal circumstances, bacteria and fungi need a certain temperature to grow and reproduce, but under special conditions such as low temperature, bacteria will go into a dormant state and no longer reproduce, that is to say, the number of bacteria carried by meat has not changed after being stored for a certain period of time, and of course it can continue to be eaten.
But if you take it out to eat, there will be a thawing process. In this process, because the cell membrane of meat has been destroyed by low temperature, it is likely to lead to the loss of nutrients during thawing, thus greatly reducing the nutritional value of meat. When you buy meat, you'd better wash it, cut it into small pieces and freeze it in the refrigerator. Eat if you want. If it is simply stored at room temperature, it is estimated that it will not exceed one day, and it will not exceed three days in cold storage. Meat goes bad easily. It can be preserved for a long time after freezing. It is best not to freeze for more than six months. The nutritional value of meat will not be lost within six months. On the contrary, some harmful bacteria on frozen meat will freeze to death and eat healthier.
Therefore, it is better to eat fresh meat. If you really need to store it, don't store it for too long.
