Quick-frozen food can be said to be unsanitary. Many quick-frozen foods contain a lot of bacteria, especially bulk quick-frozen foods. These bacteria may bring in all kinds of pathogenic microorganisms before freezing because of the bacteria in raw materials, the bacteria continue to multiply during processing, and the bacteria-carrying operation of production personnel and the lack of cleanliness of machinery and equipment. Although low temperature can inhibit the reproduction of microorganisms, it can't effectively kill them. Once it is restored to a suitable temperature, microorganisms will become active again, thus increasing hidden dangers to health.

Extended data:

Fresh food contains high nutrients, while quick-frozen food will lead to the loss of nutrients. In real life, quick-frozen jiaozi is a very common quick-frozen food. Because the temperature is too low, some nutrients of vegetables and meat stuffing will be lost during processing, and vitamins in food will be slowly decomposed during transportation and storage. Moreover, with the longer storage time, the loss of these nutrients will become more and more serious. Therefore, compared with homemade fresh food, the nutritional value of quick-frozen food has actually been greatly discounted.
