The white sediment appears at the bottom of the pickle, which is because the salt acts on the normal metabolites produced by the vegetables themselves and the normal crystal mixture of salt: the main ingredients are calcium oxalate, fermented bacteria corpse, vegetable fiber, salt and other attachments. It's harmless, but remember to distinguish it from Baipu. Baipu floats above the pickle jar, and this kind of sediment only exists at the bottom of the pickle jar
Is it normal to have white sediment at the bottom of pickles
It is normal for pickles to have white sediment at the bottom of the pickle jar. The white precipitate should be that too much salt was added to the pickle, and the salt concentration of the excessive salt became higher after the acid water slowly evaporated, and it was slowly resolved from the pickle water to form a precipitate, which would slowly melt away as the number of times of adding fresh vegetables increased.
In addition, the pickles will sink to the bottom of the jar if they are not taken out in time due to the insufficient amount of mixed bacteria or salt.
Is it normal to have white sediment at the bottom of pickles
In the pickle jar, there will be some air at the mouth of the jar, which is inevitable. Therefore, the oxygen content in the surface soup is relatively high, the concentration of lactic acid bacteria is the lowest, and the concentration of mixed bacteria is the highest, so it is easy to produce foam.
When stirred, the soup on the surface will be mixed with the soup on the bottom, thus increasing the concentration of lactic acid bacteria in the soup on the surface. Because lactic acid bacteria belong to anaerobic bacteria, they cannot reproduce in large quantities in the presence of oxygen. Many miscellaneous bacteria are aerobic and will multiply in the presence of oxygen. If the reproduction of miscellaneous bacteria is inhibited, white foam will not be produced.
