2. The storage time of frozen meat is not only related to the storage temperature, but also related to the variety of meat and the freshness of meat before freezing. Frozen meat is in an ideal state, that is, fresh and pollution-free meat is quickly frozen below MINUS 25℃ and stored at MINUS 65438 08℃, and the shelf life of pork, beef and mutton can reach 2 years.
3. Although the theoretical shelf life of frozen meat is long, it is difficult to guarantee the freshness of raw materials because the meat bought from supermarkets is easily contaminated by bacteria in the sales process. In addition, the frequent opening and closing of household refrigerator doors and sudden power failure will make the refrigerator temperature fluctuate. Therefore, all kinds of meat purchased from supermarkets should be eaten within 1 month after freezing.
