Can pork be eaten after hanging in the refrigerator for a year?

Generally, the temperature of the freezer in household refrigerators is around-18℃, which can only preserve the flavor, nutrients and freshness of food for a certain period of time, but it cannot prevent the gradual loss of nutrients and the slow deterioration of food quality.

So it's best not to freeze fish and meat in the refrigerator for more than two months, otherwise you won't enjoy the original delicacy and nutrition of the food.

According to national standards, it is best to eat bulk meat bought in supermarkets within two months. In addition, it should be reminded that: 1. After buying it back, the freezing temperature should also be kept at-14 degrees Celsius. 2. Usually, the refrigerator door should be opened as little as possible, because every time the door is opened, the ambient temperature of the freezer may rise, which will affect the fresh-keeping effect of meat.

Experts tell us that the longer meat food is frozen in the refrigerator, the greater the possibility of fat oxidation, and the process of fat oxidation will produce mild oxides and carbonyl compounds, which is very harmful to the body. If you find that the fat in the meat has turned yellow, it means that it has been oxidized. It is best not to eat this kind of meat.
