Potassium sorbate --- colorless to white flaky crystals or crystalline powder, odorless or slightly odorous. Unstable in the air. Can be oxidized and colored. Molecular weight 150.22. Hygroscopic. Easily soluble in water and ethanol. Mainly used as a food preservative, it is an acidic preservative and the preservative effect is improved when used with organic acids. It is made from potassium carbonate or  sorbic acid.
Application:
Sorbic acid (potassium) can effectively inhibit the activity of molds, yeasts and aerobic bacteria, thereby effectively extending the shelf life of food and maintaining the original flavor of food. When we buy packaged (or canned) food, we often see the words "sorbic acid" or "potassium sorbate" in the ingredients. In fact, they are commonly used food additives. Sorbic acid (potassium) is an acidic preservative. It still has a good preservative effect in foods close to neutral (PH6.0-6.5) (not suitable for dairy products). Sorbic acid (potassium) is an efficient and safe preservative recommended by the Food and Agriculture Organization and the World Health Organization. It is widely used in food, beverages, tobacco, pesticides, cosmetics and other industries. As an unsaturated acid, it can also be used in resin, fragrance and rubber industries.
