The difference between refrigeration and freezing

Views: 5502/10/2020  

1. The difference between refrigeration and freezing: both of them have a word of "cold", but the temperature is very different. Cold storage is a kind of preservation method which can keep food under normal temperature and keep it in nonfreezing state, and prolong the fresh-keeping period. The general temperature of refrigeration is about 1 ~ 10 ℃, which is suitable for the storage and preservation of vegetables, fruits, drinks, and dairy products. The fresh-keeping period of the commodity is short, and the meat is about one to three days.

2. Freezing is to reduce the temperature of food and other things. It means that the goods are frozen and solidified, so they can be stored and transported better. The freezing temperature is generally around - 18 ℃, and the temperature of some special freezers can even reach - 60 ℃ or lower. It is mainly cold room for seafood, meat, some vegetables, frozen food, etc. The preservation period of frozen goods is longer, generally about half a year to one year.

3. It should be noted that it is forbidden to refrigerate or freeze frozen food twice after thawing. In the process of thawing, the activity of bacteria and microorganisms increased, and the deterioration reaction has begun. When the food is refrigerated and frozen for the second time, it is easy for Gu Aiwen to appear in the food. Some of the low-temperature bacterial activities are enhanced, which is easy to cause food pollution, diarrhea or other problems, and harm health.
