Cold storage and freezing storage are the cold storage, but there are obvious differences between them.
Cold storage is only through the low temperature to reduce fresh food, crops, seed and other life activities, to extend the freshness of the shelf life, and this time the life of food is still there, but very weak.
Frozen fresh is the first to freeze the food and then store the food once frozen, the life of the activity can be completely stopped, can be long-term preservation. The advantage of frozen storage is that the preservation period is much longer than that of the cold storage, and the food is completely stopped. But the disadvantage is that the frozen fresh food will cause a certain degree of damage to the organization structure of food.
Fresh food to use which kind of cold storage, we must look at the characteristics of food. For example: fruits, vegetables, and more suitable for the use of frozen storage, meat, seafood can choose frozen storage.
