The State Food and Drug Administration reminds: Do not store vinegar in stainless steel containers
The storage of vinegar is exquisite：
It has a high degree of acetic acid, so do not store it in a stainless steel container. It is best to store it in a glass bottle. Vinegar produced by solid-state fermentation with grains as raw materials is prone to precipitation during storage. It is normal if there are no other abnormalities during the shelf life and can be eaten with confidence. After the product is opened, pay attention to cover at any time to reduce the volatilization of product flavor substances and the pollution of dust and microorganisms in the environment.
