In the freezer, refrigeration and freezing refer to different temperature ranges. Generally speaking, the following are their differences:

1. Temperature range: Refrigeration is generally maintained at around 0℃~10℃, while freezing usually requires a lower temperature, which can reach -18℃ or below. .

2. Different uses: Refrigerators are mainly used to store perishable foods such as vegetables, fruits, and meat to extend their shelf life. The freezer is mainly used to freeze meat, fish, shrimp, frozen food and other long-term food.

3. The storage time is different: Refrigeration can only achieve short-term preservation effect for most foods because the temperature is not low enough; while freezing can preserve many foods for a long time, even several months or more. Long.

4. Different impacts on food: Refrigeration can extend the shelf life of food, but the water in it will evaporate, resulting in a reduction in food quality; freezing locks the water in the solid state, slowing down material activities, greatly Reduces the possibility of food spoilage.

In summary, although refrigeration and freezing in the freezer are both food preservation, there are obvious differences and different uses in actual use.
