As we all know, fresh food contains high-white 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, vegetables and meat stuffing will lose some nutrients during processing, and vitamins in food will slowly decompose during transportation and storage. And with the storage time getting longer and longer, 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 reduced.
2. The total number of quick-frozen food colonies exceeded the standard.
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 various pathogenic microorganisms before freezing because of the bacteria in raw materials, the continuous reproduction of bacteria during processing, the bacteria-carrying operation of production personnel and the uncleanness of machinery and equipment. Although low temperature can inhibit the reproduction of microorganisms, it can not effectively kill them. Once the temperature is restored to an appropriate level, microorganisms will become active again, thus increasing the hidden danger to health.
3, make food oxidized and deteriorated.
? During the storage of frozen food, with the oxidation of fat, the taste and appearance will change or even deteriorate, which is a great threat to health.
4, drinking ice water and eating cold drinks for a long time, the body temperature drops rapidly.
The brain "mistakenly thought" that the heat inside the human body had been emitted, so it "ordered" to stop the heat removal work. As a result, sweat holes are difficult to dissipate heat, residual heat accumulates, and heatstroke is more likely. Ice water and cold drinks easily irritate the throat and stomach, causing sore throat, hoarseness, diarrhea and abdominal pain. Some women drink ice water and cold drinks for a long time, which is easy to cause irregular menstruation. Drinking cold water for a long time will slow down the blood circulation of peripheral nerves of limbs, affect the speed of human body's metabolism of waste, make it easy for the body to accumulate too much toxins, and make the body slowly lose shape and get fat. Therefore, we should drink more warm water instead of ice water to dilate blood vessels and improve circulation problems.
