Potassium Sorbate

Sorbic acid and Potassium sorbate are the commonly used antiseptic agents in the international market. They have been described as the "Generally Recognized as Safe"brands food additives by American FDA and they also have been listed into the Application Hygienic Standard for the Food Additive of China GB2760-1996. The WHO Additive Committee's research has indicated that: people can safely absorb more amounts from the sorbic acid and potassium sorbate than from the vitamin C, therefore, it is one of the antiseptic agents which are allowed for use.


The sorbic acid and potassium sorbate have higher safety and stronger inhibiting capacity to the mould, their acute toxicity is just half of the salt's; and have not occur the phenomenons for causing cancer and malformation. In America, Japan, Europe and some developed developing countries and areas, they have substituted the sorbic acid and potassium for the sodium benzoate at the end of 1980's.


Main Applications: as the antiseptic agent for all kinds of food, preserved vegetable in soy, drinking, wine,etc; the antiseptic agent and additive for the pharmaceutical, nutrient solution and health products. The antiseptic agent and additive for the cosmetic and chemical industry concerned with products for daily use; the reaction additive for the petrochemical industry; synthetic additive for the plastic,rubber, fibre and coating industries; the feed additive; for keeping fresh of the flower and vegetable; foodstuff's storage and mould proof and so on.


Specific Application : Has been used extensively in food, drink, vegetables in soy, tobacco, drugs, cosmetic, agricultural products, forage and other domain as preservative Preservative efficiency of Sorbic Acid is 5 – 10 times Sodium Benzoat Potassium Sorbate ( Sorbic Acid ) can restrain effectively the activity of mould , yeast and aerophile bacteria, and restrain growth and reproduction of the pernicious microorganism as pseudomonas, Staphy lococcus Salmonella, and then action to restrain growth is more powerful than killing. Can be used by direct adding, spraying, retting, dry spraying, using in packing material and other methode
