Potassium sorbate, also known as potassium 2,4-hexadienoate, is the potassium salt of sorbic acid, with the molecular formula C6H7O2K, white to light yellow scale crystals, crystal particles or crystal powder, odorless or slightly odorous, long-term exposure to air Easy to absorb moisture, be oxidized and decomposed to change color. Soluble in water, soluble in propylene glycol and ethanol. Often used as a preservative.

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%.
