Potassium sorbate (K-sorbate) is a food preservative commonly used in the baking industry to prevent mold, yeast, and microbes. It is often used in cakes and icings, beverage syrups, cheese, dried fruits, margarine, pie fillings, etc.
Potassium sorbate is used to inhibit molds and yeasts in many foods, such as cheese, wine, yogurt, dried meats, apple cider, rehydrated fruits, soft drinks and fruit drinks, and baked goods. It is used in the preparation of items such as hotcake syrup and milkshakes served by fast-food.
It can also be found in the ingredients list of many dried fruit products. In addition, herbal dietary supplement products generally contain potassium sorbate, which acts to prevent mold and microbes and to increase shelf life. It is used in quantities at which no adverse health effects are known, over short periods of time. Labeling of this preservative on ingredient statements reads as “potassium sorbate” or “E202”.
Also, it is used in many personal-care products to inhibit the development of microorganisms for shelf stability. Some manufacturers are using this preservative as a replacement for parabens. Tube feeding of potassium sorbate reduces the gastric burden of pathogenic bacteria.
