It is said that zombie meat has no nutrition, so what is zombie meat?

Foods such as meat are stored in a frozen low temperature environment. In which microorganisms themselves stop reproducing and growing, and biochemical reactions also stop. In other words, it will not produce toxic substances harmful to health. In other words, if the freezing temperature and the sanitation and safety of food storage environment are fully guaranteed, frozen food can be stored indefinitely, but it has little impact on food safety. Of course, in addition to food safety, it will also be affected by other aspects such as smell, appearance and taste. For frozen meat, if you buy frozen meat with guaranteed quality, it has been frozen without opening it. Even if it exceeds the shelf life stipulated by the manufacturer, there is not much problem in eating.

Zombies refer to frozen meat that has been frozen for many years and sold everywhere. Most of them refer to smuggled goods, and the safety and quality cannot be guaranteed. Many businessmen buy zombie meat and use food additives or even illegal additives to process and flavor it. Meat will become a taste after processing and cooking. For example, it is generally difficult to distinguish mutton skewers and smoked sauce meat produced by some unscrupulous businessmen. Eating this kind of processed smuggled meat, which may pose a threat, will increase the risk of food poisoning, and even cause vomiting, diarrhea and abdominal pain. Eating illegally added smuggled meat may cause more serious harm to the body.

Zombie meat generally refers to meat frozen for a long time. This period of time does not exceed one year, generally more than three years. Because meat can be kept in a frozen state in a large freezer, that is, at a temperature below MINUS 20 degrees, it will not deteriorate for more than one year. Zombie meat refers to meat that has exceeded the storage period and has potential safety hazards. At the same time, the zombie problem is not mainly a nutritional problem. Under long-term freezing, fatty acids begin to decompose and rot, and vitamins begin to lose a lot, which is not the main problem. The main problem is food safety. Because even at very low temperatures, bacteria can reproduce slowly. Because as long as there is enough time, bacteria can reproduce to a safe critical level.

After talking so much about zombies, I actually don't think it has anything to do with frozen meat for a month. Because taking livestock meat as an example, it is not a problem at all to keep it in the freezer of household refrigerator for 6~8 months, so the nutrition and safety will not change much. At extremely low temperature, the chemical reaction of meat itself and the activity of attached microorganisms are greatly inhibited, so there is no need to worry about how much nutrients will be lost after 30 days of freezing. At the same time, even if there is a slight loss of nutrients in this process, it will focus on fat-soluble vitamins such as vitamin A, but eating meat is to obtain protein and B vitamins and minerals. These nutrients can be said to have no effect on short-term freezing.
