Potassium sorbate is the potassium salt of sorbic acid, chemical formula CH 3 CH=CH−CH=CH−CO 2 K. It is a white salt that is very soluble in water (58.2% at 20 °C). It is primarily used as a food preservative (E number 202). [4] Potassium sorbate is effective in a variety of applications including food, wine, and personal-care products.
Sodium benzoate is also allowed as an animal food additive at up to 0.1%, per the Association of American Feed Control Officials. [9] Sodium benzoate has been replaced by potassium sorbate in the majority of soft drinks in the United Kingdom. [10]
Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria. It works best in low- pH products, below 4.5, where it exists as benzoic acid.
It has been reported that many food preservatives, including sorbitan, hydrogen peroxide, benzoic acid and sodium benzoate, can cause health problems, especially in high doses. [16] In addition, as mentioned in the controversy section, the adverse effects of sulfites on asthma patients also confirmed the health threat of preservatives ...
Sorbic acid and its salts, especially 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. In general the salts are preferred over the acid form because they are more soluble in water, but the active form is the acid.
Potassium acetates – preservative, acidity regulator; Potassium adipate – food acid; Potassium alginate – thickener, vegetable gum, stabilizer, gelling agent, emulsifier; Potassium aluminium silicate – anti-caking agent; Potassium ascorbate – antioxidant (water-soluble) Potassium benzoate – preservative; Potassium bicarbonate ...

Sub-acute, sub-chronic and chronic toxicity studies did not show any adverse effects at concentrations up to 9 200 mg/kg body weight (bw)/day in rats. Given the lack of genotoxicity data on calcium sorbate and the available positive genotoxicity data on sodium sorbate, the Panel concluded that calcium sorbate should be excluded from the group ADI.
