If the cold storage time is too long, more than two to three months, even if it is not completely moldy, the taste will get worse and worse. It will be more serious, leading to the outflow of nutrients and the increase of bacteria.

Frozen food will not only lose a lot of nutrients during the shelf life, but also cause mildew. For example, the shelf life of a frozen food at-18℃ is three months, but it does not mean that it can be stored at -8℃ for three months.

Raw jiaozi is directly refrigerated:

We can separate the wrapped jiaozi one by one, then put it in a box, sprinkle some flour, and then refrigerate it in the refrigerator.

Flour is mainly used to prevent jiaozi from sticking together one by one, so that dumpling wrappers will not stick together, and flour plays a role in lubrication.

Refrigeration is to prevent it from going bad. Of course, this storage method is usually eaten up in two to three days.
