What's the difference between freezing and refrigeration? What should be frozen and what should be refrigerated?
First, the difference between freezing and cold storage

1, different temperatures

Freezing: The freezing temperature is relatively low, which can reach minus 18 degrees Celsius.

Refrigeration: The temperature of refrigeration is generally kept at 1- 10 degrees Celsius.

2, the principle is different

Freezing: Freezing temperature slows down the enzyme reaction and makes microorganisms stop growing, thus slowing down food spoilage and prolonging food preservation time.

Refrigeration: The temperature of refrigeration reduces the speed of food spoilage and chemical reaction, which makes the water in food turn into ice, which seriously hinders the growth of microorganisms, thus prolonging the best eating time of food.

3. Different equipment

Freezing: Freezing equipment is generally a freezer or freezer.

Refrigeration: Refrigeration equipment is usually ordinary refrigerator and freezer.

2. Types of food suitable for preservation in freezing and refrigeration

Freezing is suitable for preserving fish, shrimp, fresh meat and other foods to avoid spoilage.

Refrigeration is suitable for the preservation of most vegetables, fruits and surplus food dishes.
