The whitening of acid altar is mostly due to deterioration. If the sour taste is heavy, it means that the kimchi has gone bad at this time, so don't eat it any more. If the soup of kimchi is still clear, but there is a layer of foam on the surface, you can boil water, add salt, and then inject salt into the foam, and the effect will be very good.

You can also add some white wine when the acid altar turns white, so it will be fine in a few days.

If you have purple potatoes at home, it is also good to add perilla to the pickle jar at this time.

When the acid altar turns white, you can also add some green pepper, bitter gourd or pepper leaves to quickly eliminate the taste. If there is no green pepper, garlic and ginger can also be added. And the effect is also very good.

Adding some raw celery stalks often works well and can prevent foaming.

There is air in some cans of kimchi, which is easy to produce foam and can be stirred at any time. When stirring, the soup on the surface will be mixed with the soup on the bottom, so there will be no more foam.
