Frozen food can be divided into chilled food and frozen food. Frozen food is easy to preserve and widely used in the production, transportation and storage of perishable foods such as meat, poultry, aquatic products, milk, eggs, vegetables and fruits. Nutrition, convenience, hygiene and economy; The market demand is large, which occupies an important position in developed countries and develops rapidly in developing countries.

In China, the related industries supporting the quick-frozen industry, such as flour processing industry, meat and poultry breeding and slaughtering, and cold chain transportation, are far behind the development of the quick-frozen food industry. Affected by production technology, transportation and other conditions, the quality of quick-frozen food products is still slightly insufficient. Constrained by the industrial chain, the so-called "Staphylococcus aureus" can meet the standards in the production process, but it is difficult to guarantee in the transportation, circulation and terminal. The cold chain, cold storage and freezer of retail terminal in the transportation process may not meet the standards. On the one hand, it is fierce competition and harsh competitive environment, on the other hand, it is a huge market space.

In the international market, more than 60% of frozen food is used in catering industry, while the proportion in China is less than 5%. The huge market will trigger the rise of the quick-frozen food business market and provide new business opportunities and space for the development of the quick-frozen food industry.
