Quick-frozen jiaozi is generally produced in batches by machinery, and the packaging is also mechanized, which greatly reduces the labor cost. In addition, in terms of efficiency, jiaozi is always wrapped by hand in our home. But supermarkets are different. They are pressed by molds one by one, and the production efficiency will be much faster than manual work.

With the development of China's social economy and the improvement of people's living standards, the frozen chains in shopping malls are becoming more and more popular and perfect, and the sales of frozen foods have increased greatly. As an important part of quick-frozen food, quick-frozen jiaozi has developed rapidly because of its delicious taste, convenient eating, nutrition and hygiene. However, with the emergence of many manufacturers, the market competition is very fierce.

Fierce market competition makes the price of quick-frozen jiaozi in China extremely low, and various manufacturers have come to the era of low profit, and have launched a series of hand-made high-end products to cope with the supply-side reform.

Extended data

1, don't buy bulk jiaozi.

Although the price of bulk dumplings is cheaper than that of packaged dumplings, there is no way to guarantee their freshness, which means we don't know their production date and shelf life, and the preservation environment is worrying. I don't know how many people touched it when it was scattered, so pollution is inevitable.

2. Don't buy more cream.

If there is a lot of frost on the surface of jiaozi, it is likely that the dumpling skin was squeezed or melted and frozen during transportation, indicating that the skin has been broken and the inside of jiaozi is not fresh. Purchase is not recommended.

3. Don't buy unknown brands.

This is because jiaozi, an unknown brand, has no quality guarantee. Big brands will definitely guarantee the quality of products, otherwise the losses will be huge. Never save a few dollars to buy an unknown brand of jiaozi.
