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%.
