It may cause stomach trouble, so don't eat it often. Frozen food itself is harmless, but from a nutritional point of view, it is not as fresh as it is. It's not a harmful substance, but because the nutrients in frozen food are incomplete, and the lack of nutrients will harm your health! Moreover, the vegetables in quick-frozen jiaozi have salt, which is more likely to produce nitrite. Eating too much nitrite is easy to cause cancer, so it is better to eat fresh vegetables.

Second, it is not fresh. Bulk sales, no matter when sales staff unpack and sell in bulk, or in the process of customer selection, people inevitably come into contact with food, causing bacterial pollution; However, the contact area between bulk food and air is large, which will also cause water evaporation, product cracking and oil oxidation rancidity. At the same time, microorganisms and viruses in the air are likely to pollute food, leading to unsafe eating.

Matters needing attention in eating quick-frozen jiaozi:

Quick-frozen jiaozi is not easy to make. If you cook with strong fire, the skin will be cooked and the stuffing will be raw. Therefore, jiaozi should cook slowly with medium and small fire. If you don't thaw, throw it into the pot when jiaozi is still hard, or wait for jiaozi to thaw naturally, and the whole skin will be sticky and easy to cook. Boiling jiaozi in water and adding some salt can increase the boiling resistance of dumpling skin and prevent it from cracking due to tension. Boil the pot with boiling water and stir it with a spoon from time to time to avoid the dumpling skin sticking to the pot. When jiaozi boils, pour a little cold water to cool down. After the water is boiled again, add cold water and repeat it for three times. You can take it out and enjoy it after jiaozi comes up.
