Why is there a difference between Maximian burrito quick freezing and normal temperature?

1, different in nature: quick freezing is rapid freezing to make food form tiny ice crystals, which will not seriously damage cells and tissues, thus retaining the original juice and flavor of food. Normal temperature is also called general temperature or room temperature, which is generally defined as 25℃.

2. Different characteristics: in summer, aquatic quick-frozen food can be stored for up to one day at room temperature, agricultural quick-frozen food can be stored for several hours at room temperature, and conditioned quick-frozen food can only be stored for a short time. If steamed, it can be kept for one day. Because it is hot in summer, many quick-frozen foods will go bad at high temperature.

3. Different hazards: quick-frozen food is easy to breed bacteria at room temperature, which may bring in various pathogenic microorganisms before freezing because of the bacteria in raw materials, the continuous reproduction of bacteria during processing, the operation of the production personnel with bacteria, and the unclean machinery and equipment. At room temperature, microorganisms tend to become active again, especially in the case of thawing and freezing, which is more dangerous to deteriorate.
