Potassium Sorbate As A Food Preservative

Potassium sorbate is the potassium salt of sorbic acid, a naturally occurring compound found in some plants. It is typically manufactured synthetically for use as a food additive. It works by inhibiting the growth of mold, yeast, and some bacteria.

Potassium sorbate is widely used as a food preservative to extend shelf life by preventing spoilage. It is effective in acidic foods and is commonly found in products like cheese, baked goods, dried fruits, yogurt, and beverages.

Potassium sorbate is generally recognized as safe (GRAS) by the FDA for use as a food preservative. Regulatory bodies like JECFA and EFSA have evaluated potassium sorbate and found it safe for consumption at typical levels. Some individuals may experience mild allergic reactions or sensitivities, such as skin rashes or digestive upset, though this is uncommon.
