Sorbic acid and its mineral salts, such as sodium sorbate, potassium sorbate and calcium sorbate, are antimicrobial agents often used as preservatives 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.
The optimal pH for the antimicrobial activity is below pH 6.5 and sorbates are generally used at concentrations of 0.025% to 0.10%. Sorbic Acid is a mold inhibitor. It inhibits mold from growing. It does not kill already established mold.
