If the container of pickled food is not cleaned, white foam often appears. To prevent pickles from being contaminated by miscellaneous bacteria, there are mainly the following ways to prevent them:
1, you can choose a small container with good sealing, such as a can bottle, and marinate it a little at a time, and then marinate it after eating.
2. Appropriate amount of white wine can be added to kimchi, which can inhibit the growth of miscellaneous bacteria on the surface of kimchi and increase the mellow taste.
3. The concentration of brine used for pickles should not be too low. It is best to boil it before using it, in order to kill the miscellaneous bacteria in the salt.
