Background

Thawing frozen food is the process in which ice crystals in cells melt and are absorbed by the food, and the food returns to a fresh state before freezing. During thawing, as the temperature increases, the microbial reproduction rate and the biochemical reaction rate of the frozen food increase. If the ice crystals have little damage to the cellular tissue and proteins when the food is frozen, then in a reasonable thawing pattern, the thawed water slowly re-penetrates into the cells, reforming a hydrated layer around the protein particles, and reducing juice loss. Therefore, a suitable thawing method should be selected to ensure the quality of the thawed food product.

At present, frozen food thawing modes mainly comprise modes of thawing in a refrigerating chamber, thawing in natural air and thawing in water, wherein the frozen food is electrolyzed such as low-frequency, high-frequency, microwave, far infrared and high-voltage electrostatic fields, the thawing period generally required by the thawing in the refrigerating chamber is longer, and the air thawing and the water thawing easily cause microbial pollution in the thawing process so as to influence the quality of the thawed food.
