Quick-frozen food should develop the concept of green food

Actively develop quick-frozen food with the concept of green food. Due to the development of high technology and the improvement of people’s living standards, the quality requirements for quick-frozen food are also getting higher and higher. The development of green quick-frozen food that is safe and hygienic, meets environmental protection requirements, has a wide variety, and is of high quality and low price is a major development trend in the industry. It is the requirement of sustainable development. At the same time, the improvement of food processing technology has also promoted the development of green food. The development trend of the quick-frozen food industry is the ultra-low temperature freezing of quick-frozen food. The development direction of my country's quick-frozen food industry is to directly spray liquid nitrogen, liquid freon, and liquid carbon dioxide in refrigeration devices that can reduce the temperature to a cryogenic degree much lower than that of ammonia compressors, making ultra-low temperature freezing possible.
