Pigskin is rich in protein, which helps us to speed up metabolism. Low fat content and high quality carbohydrates can provide more energy for our body.

Frozen meat refers to the meat that is quickly frozen below minus 25℃ after slaughter, and its temperature must be controlled below minus 65438 08℃ during storage, transportation and sales.

Therefore, if you can't finish eating the homemade frozen pigskin on the same day, you can keep it in the freezer of the refrigerator for no more than one month, otherwise the food will go bad and do harm to our health.

Extended data:

Freezing pigskin and frozen meat for too long will bring the following effects:

1, safe

The low temperature in the freezer can prevent bacteria from multiplying, but it can't completely prevent the oxidation of fat and protein, so it can't completely prevent the deterioration of meat quality. Due to the oxidation reaction, the color of lean meat frozen for a long time will gradually change from red to brown, and the fat will gradually turn yellow, which will not only make the flavor worse, but also produce fat oxidation products that accelerate human aging.

2. Nutrition

There is a great loss of vitamins. Frozen meat not only tastes bad, but also decomposes essential amino acids if protein is oxidized. The longer the freezing time, the greater the loss of vitamins, especially B vitamins.

Step 3 taste

Hard and firewood. Experts say that long-term freezing will greatly affect the taste of meat. Chen said that the cells of fresh meat are rich in water and fiber, so the taste is tender and juicy. When frozen, the water in the meat will sublimate; When thawing, due to the osmotic pressure, the residual water in the cells will flow out, resulting in the hardness of the taste and the loss of umami flavor.
