Background

With the development of society in recent years, the living standard of people is gradually improved. China has already comprehensively built a well-being society in 2020, on the basis, people have higher and higher requirements on high-quality living standard and new requirements on diet are provided, and people have no longer the full requirement on treating diet problems but have to eat well and have good health. Therefore, the requirements of people on seafood, meat imported food, fruits, vegetables and other food in modern times need to be met by a quick-freezing method, and how to ensure the original color, aroma, taste, appearance and nutritional quality of the food during thawing is very important.

There are four conventional thawing methods, namely: soaking in water, thawing, refrigerating, thawing at constant temperature, thawing by microwave oven heating, and thawing by natural standing. The four thawing methods have respective advantages and disadvantages, wherein the soaking thawing method is as follows: quick-frozen food is put into hot water or warm water for quick thawing, but bacteria can be bred in the thawing process, and nutrient substances contained in the food can be greatly lost along with the thawing process; the refrigeration constant-temperature thawing method comprises the following steps: the quick-frozen food is put into a refrigerator for refrigeration and thawing at constant temperature, so that the nutrition of the food can not be lost, the appearance of the food can not be changed, but the required thawing time is too long, and the taste of the food is easily influenced; the microwave oven heating unfreezing method comprises the following steps: the food is quickly thawed by a method of heating the food by a microwave oven, but simultaneously, the nutrition of the food is damaged to a certain extent, and the taste of the food is changed; the natural static thawing means: the quick-frozen food is unfrozen in a natural state, the taste and the nutritional structure of the food cannot be damaged, but the unfreezing time is too long.

The natural static thawing method in the four methods can be thawed in a natural state, does not affect the nutrition, taste and flavor of food, is most energy-saving and popular, but has the thawing time which is far longer than that of other thawing methods, so that the method is extremely important for providing the efficient natural static thawing method.
