Sorbic acid

Sorbic acid is a natural organic compound used as a food preservative.The traditional route to sorbic acid involves condensation of malonic acid and trans-butenal.Sorbic acid was isolated in 1859 by distillation of rowanberry oil by A.W von Hofmann.Sorbic acid and its salts, such as sodium sorbate, potassium sorbate, and calcium sorbate, are antimicrobial agents often used as preservatives in food and drinks to prevent the growth of mold, yeast, and fungi.The optimal pH for the antimicrobial activity is below pH 6.5. Sorbates are generally used at concentrations of 0.025% to 0.10%.
Sorbic acid should not be confused with other unrelated, but similarly named food additives sorbitol, polysorbate, and ascorbic acid.The sorbic acid is the international food and agriculture organization (fao) and health organization recommended efficiency and security BaoXianJi anticorrosive, is widely used in food, beverage, tobacco, pesticide and cosmetic industries, as unsaturated acids, also can used for resin, spices and rubber industry.
The sorbic acid as food additives mouldproof effect is good, do not change characteristics, wide range of application of food, use convenient. In the use of the sorbic acid and potassium, can be directly add, also can spray or soaking. It is because of its use of flexible with characteristics, so, the United Nations food and agriculture organization and the world health organization, the United States, Britain, Japan and China, southeast Asia countries, all recommended the sorbic acid and potassium DuoZhong food anticorrosion BaoXianJi as.
It can strengthen the latter effect, but can never replace them. The sorbic acid in the water solubility isn't very big, it's a soluble form is potassium sorbet. 270 g/L of potassium sorbate solution contains 200 g/L sorbic acid. The sorbic acid to human body won't produce causes cancer and birth defects role. Because the sorbic acid in the water solubility is not very high, influence it in food applications.
