Potassium sorbate Usage
Chemical Properties Potassium sorbate was first discovered by the French in the 1850s, having been derived from the mountain ash tree. It is widely used in the food industry and few substances have had the kind of extensive, rigorous, long-term testing that sorbic acid and its salts have had. It decomposes at about 270°C. For a detailed description of this compound, refer to Burdock (1997).
Chemical Properties White powder. Soluble in water (25C).
Occurrence Reported found in blueberries.
Uses potassium sorbate is a preservative primarily against mold and yeast, and used in concentrations of 0.025 to 0.2 percent. It is non-toxic but may cause mild skin irritation.
Uses Pharmaceutic aid (antimicrobial agent).
Uses Potassium Sorbate is a preservative that is the potassium salt of sor- bic acid. it is a white crystalline powder which is very soluble in water, with a solubility of 139 g in 100 ml at 20°c. this solubility allows for solutions of high concentration which can be used for dipping and spraying. it is effective up to ph 6.5. it has approxi- mately 74% of the activity of sorbic acid, therefore requiring higher concentrations to obtain comparable results as sorbic acid. it is effec- tive against yeasts and molds and is used in cheese, bread, beverages, margarine, and dry sausage. typical usage levels are 0.025–0.10%.
