Potassium sorbate
Potassium sorbate, also known as potassium 2,4-hexadienate, is a potassium salt of sorbic acid with the molecular formula C6H7O2K. It is a white to light yellow flake like crystal, crystal particle or powder, odorless or slightly odorous, and is prone to moisture absorption, oxidation and decomposition, and discoloration after long-term exposure to air. Easily soluble in water, soluble in propylene glycol and ethanol. It is often used as a preservative and damages many enzyme systems by binding with thiol groups in microbial enzyme systems. Its toxicity is much lower than other preservatives and is widely used. Potassium sorbate can fully exert its anti-corrosion effect in acidic media, but its anti-corrosion effect is small under neutral conditions.

Both the United States and the European Union use potassium sorbate as a statutory feed additive in animal feed. Potassium sorbate can inhibit the growth of mold in feed, especially the formation of aflatoxin, which has a very significant effect. Therefore, adding potassium sorbate can effectively prevent feed spoilage and can still resist microbial growth in animal intestines. In addition, the neutral taste of potassium sorbate is suitable for use in feed because animals are more sensitive to changes in food taste than humans. In addition, as an unsaturated fatty acid, potassium sorbate can be considered as a feed ingredient and is easily digestible without any adverse effects on animals. Feed is prone to spoilage during storage, transportation, and sales, thus the application market of potassium sorbate in the feed industry is huge.
