Tips:
1. After the vegetables are pickled in refined salt, they will taste crispy in the sauce.
2. Pickled vegetables should be pickled for more than 7 days before eating, which can partially reduce the damage of nitrite.
In the process of storage and pickling, vegetables will produce large amounts of nitrite under the action of bacteria. However, when bacteria decompose nitrous acid, they produce acidic substances such as acetic acid and lactic acid, which can decompose nitrite.
Therefore, when pickling vegetables, the content of nitrite will generate, increase, decrease, and then disappear. The pickles react with salt (sodium chloride) to produce sodium nitrite and then sodium nitrate. Sodium nitrate is not harmful to the human body.
