Use of potassium sorbate
How to use potassium sorbate? There are many ways to use 1. potassium sorbate, such as direct addition, spraying, dip coating, dry powder spraying, and treatment on packaging materials. Compatibility with alkali, oxidant and reducing agent has contraindications.

2. When sorbic acid meets nonionic surfactants and plastics, its antibacterial activity will decrease. Heavy metal salts can catalyze the oxidation reaction. Sorbic acid can also react with sulfur-containing amino acids, but adding vitamin C, propyl gallate or butylated hydroxytoluene can inhibit this reaction.

3. When the solution is stored in a glass container, it is very sensitive to pH value. Therefore, the preparation with potassium sorbate as preservative needs to detect the number of microorganisms after long-term storage.

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

4. Potassium sorbate is an efficient and safe preservative, which is widely used in food, beverage, tobacco, cosmetics and other industries. As an unsaturated acid, potassium sorbate can also be used in resin, perfume and rubber industries.
