Secondly, it's best not to keep raw crabs with the refrigeration equipment at home. Because the refrigeration equipment at home is only conventional refrigeration, and the temperature in the freezer is very low, this will lead to changes in the texture and flavor of raw crabs. If the frozen raw crabs are heated again, there will be serious dehydration of muscle tissue and serious loss of juice, which will lead to poor taste and light flavor of raw crabs.
3. Crabs are easy to deteriorate because they are rich in water and nutrients, but after being put into the freezer, the free water in the crabs becomes ice, which is not conducive to the parasitism of bacteria. At the same time, the bacteria content in the freezer is low and can be stored for 3 months. But the content of unsaturated fatty acids in crabs is also high. If left for too long, unsaturated fatty acids will be oxidized, resulting in a decline in nutritional value, so it is not recommended to leave for too long.
