Potassium sorbate - colorless to white flaky crystals or crystalline powder, odorless or slightly odorous. Unstable in the air. It can be oxidized and colored. Molecular weight: 150.22. It is hygroscopic. It is readily soluble in water and ethanol. It is mainly used as a food preservative and belongs to acidic preservatives. When used in combination with organic acids, the preservative reaction effect is enhanced. It is produced from potassium carbonate or potassium hydroxide and sorbic acid as raw materials. Sorbic acid (potassium) is an acidic preservative and still has a good preservative effect in foods close to neutral (PH6.0-6.5) (not suitable for dairy products). Sorbic acid (potassium) is a highly efficient and safe preservative and antiseptic recommended by the Food and Agriculture Organization of the United Nations and the World Health Organization.

Product application:
As a food preservative, potassium sorbate is widely used in food and feed processing industries, and is also used in cosmetics, resins, spices and rubber industries. However, it is most widely used in food preservation and feed.
1. Animal feed industry
Potassium sorbate can inhibit the growth of mold in the feed, especially the inhibition of the formation of aflatoxin has a very significant effect, so adding potassium sorbate can effectively avoid the spoilage of the feed. In addition, the neutral taste of potassium sorbate is suitable for use in feed, because animals are more sensitive to changes in the taste of food than humans. In addition, as an unsaturated fatty acid, potassium sorbate can be easily digested as a feed ingredient without any adverse effects on animals.
2. Food containers and packaging materials
In terms of plastic production, it can be used in an appropriate amount according to production needs. For rubber, the amount used is 0.1%, and for paper, it can be used according to production needs. At the same time, there is no requirement for the residual amount of sorbic acid.
3. Food preservatives Potassium sorbate is widely used as a food preservative, and the allowed concentration in noodle products, pickles, canned food, dried fruits, dairy products and condiments is 0.02% to 0.1%.
