How to use potassium sorbate

1. It can be used by direct addition, spraying, dipping, dry powder spraying, processing on packaging materials and other methods.

2. Potassium sorbate is incompatible with alkali, oxidants and reducing agents. The antibacterial activity of sorbic acid is reduced when encountering non-ionic surfactants and plastics. Heavy metal salts can catalyze oxidation reactions. Sorbic acid can also react with sulfur-containing amino acids, but this reaction can be inhibited by adding vitamin C, propyl gallate or butylated hydroxytoluene.

3. When the solution is stored in a glass container, it is very sensitive to pH. Therefore, preparations using potassium sorbate as a preservative need to be tested for microbial content after being stored for a long time.

4. If sorbic acid solution is stored in polypropylene, polyvinyl chloride or polyethylene containers without adding antioxidants, sorbic acid will degrade quickly.
