Pork is more nutritious and healthy if it is frozen before eating. Most people think that frozen pork has no nutrition and bad taste, so they choose fresh pork with high price. Is frozen pork really nutritious? In fact, frozen pork is more nutritious and healthy to eat.
After slaughtering, pork has to go through the stages of rigor mortis, maturity, autolysis and corruption. Under normal temperature, the animal meat will enter into the dead stage after bloodletting for 1-2 hours. At this stage, the meat is hard, dry, without natural fragrance, not easy to boil and digest. After 24-48 hours, it entered the mature stage. At this time, the pork is soft, juicy, with a fragrant smell, delicious taste, easy to cook, also easy to disappear, but also can secrete a lot of lactic acid, kill harmful microorganisms. If it continues to change, it will enter the autolysis stage and the decay stage, when the pork begins to deteriorate. Until it's finally inedible. Therefore, in the mature stage of animal meat is most suitable for eating.
Frozen pork has three advantages
Fresher: pigs can enter the quick freezing process as soon as 2-3 hours after slaughtering. After more than 1 hour of thawing treatment at home, the exposure time of meat at room temperature is only about 4-5 hours, while fresh meat is generally transported from the slaughterhouse at 4:00 in the morning and sold at the meat stall. It is also the fastest time to reach the public table until noon. The exposure time of meat at room temperature and air is more than 6 hours.
Better to eat: from the perspective of meat quality, fresh meat has heavy sour taste and many impurities; and frozen meat is treated with acid expelling before storage, so the water and dirty blood in the body are basically removed, so the meat taste is more delicious. But the refrigerator at home can't keep frozen meat fresh for a long time. Because the temperature of frozen meat out of the warehouse is about - 18 ℃, and the refrigeration capacity of household refrigerators is limited, generally only about - 4 ℃, frozen meat will slowly deteriorate after long time in the freezer. Therefore, experts suggest that the frozen meat bought home should be eaten within a week.
Nutritious: compared with fresh meat, frozen meat has little difference in nutrition, but frozen meat needs to be thawed when it is eaten. Improper thawing method will cause the loss of nutrients. It should be noted that repeated thawing and freezing of frozen meat will destroy the nutrients, resulting in the loss of the most nutritious cytoplasmic fluid with water. As long as the frozen meat is thawed correctly and eaten as soon as possible, the nutritional value of frozen meat is not lower than that of fresh meat.
