Potassium sorbate is a mold and yeast inhibitor. Sorbic acid and potassium sorbate are compounds found naturally in some foods and berries (like blueberries). Potassium sorbate is generally recognized as safe as a direct food additive. It is commonly used in many foods including wine, cheese, yogurt, fruit drinks, dried meats, and baked goods. It is used in non-toxic quantities at which there are no known adverse health effects and it breaks down in the Krebs cycle into water and carbon dioxide. Not only does it have a very good safety profile, it is effective at preventing growth of molds and yeast which can have deleterious health effects, especially in children.
