First, let's look at frozen jiaozi. Many people want convenience and like the taste of frozen jiaozi. In fact, the quick-frozen jiaozi looks delicious, but it is actually high in oil content and salt content. This kind of processed stuffing food is very easy to produce microbial pollution and will be harmful to human body.
Followed by quick-frozen meat, meat mainly provides protein and minerals, but at extremely low temperature, protein and minerals will not change, so the nutritional value of quick-frozen meat will hardly be lost, but it will affect the drinking taste.
Fresh food contains high nutrients, but frozen food will lead to the loss of nutrients. Many quick-frozen foods contain a lot of bacteria, mainly taking bulk quick-frozen foods as an example. Due to the continuous proliferation of bacteria during the processing of raw materials, machinery and equipment are not clean enough, and these bacteria may bring in various pathogenic microorganisms before freezing. At low temperature, it will inhibit the reproduction of microorganisms, but there is no way to effectively kill them. Once returned to the poetic temperature, microorganisms will become active, adding hidden dangers to human health.
Frozen food will change its taste and appearance with the oxidation of fat during storage, and even deteriorate, which is a great threat to human health.
Frozen food has the above hazards. If you like to eat frozen food, I suggest you pay attention to the following points before buying.
Squeeze it to see if the food is soft and deformed or has obvious ice residue. If so, it means that the food has been thawed and it is not recommended to buy it. Then look at the production date and temperature requirements, and the closer the time, the better. Also note that you should eat as much frozen food as possible after you buy it home.
