Description and Uses
Sorbic acid, also known as herbal tea acid, 2,4-hexadienoic acid, 2-propenyl acrylic acid, with molecular formula C6H8O2, is a food additive that has inhibitory effects on many fungi such as yeast and mold. It is also used in animal feed, cosmetics, pharmaceuticals, packaging materials and rubber additives.
Sorbic Acid is a preservative that is effective against yeasts and molds. it is effective over a broad ph range up to ph 6.5, being ineffective above ph 7.0. it is a white, free-flowing powder which is slightly soluble in water with a solubility of 0.16 g in 100 ml of water at 20°c. its solubility in water increases with increasing temperatures, although it is not recommended in foods that are pasteurized because it breaks down at high temperatures. the salts are potas- sium, calcium, and sodium sorbate. it is used in cheese, jelly, bever- ages, syrup, and pickles. typical usage levels range from 0.05 to 0.10%.
