The long white hair of pickles shows that pickles are not fresh, and they begin to deteriorate and become moldy, producing toxic and harmful substances. At this time, kimchi can no longer be eaten. Eating it by mistake can easily cause gastrointestinal discomfort, diarrhea and even poisoning, which is harmful to the body.

White hairs on pickles are mainly due to the following four reasons:

1, kimchi is placed at high temperature for a long time;

2, the marinade and utensils are not clean, which is easy to breed bacteria;

3. The concentration of salt water is low, and some vegetables are exposed to the surface of salt water and produce wild yeast after contacting with air;

4. The jar was not emptied in time, and the heat generated during pickles was not radiated.
