Frozen foods include aquatic quick-frozen foods, agricultural quick-frozen foods, livestock quick-frozen foods, Chinese snacks and hot pot seasonings. 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.

Specific classification of frozen food:

1, aquatic quick-frozen foods include: sea shrimp, frozen and quick-frozen crab sticks, fish, shrimps and other seafood;

2. Agricultural quick-frozen foods include: frozen green beans, carrots, corn, quick-frozen broccoli, asparagus, green vegetables and other rich vegetables;

3. Frozen foods produced by livestock include: frozen pork, chicken and other meats;

4. Deep-fried noodles include: chicken nuggets, cola cakes, squid chops and so on, which need to be fried and eaten;

5. Hot pot seasonings include: various fish dumplings, fish balls, tribute balls and a series of balls eaten in hot pot.

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.
