Potassium Benzoate And Potassium Metabisulfite

Potassium benzoate is the potassium salt of benzoic acid, a substance found naturally in some fruits. Potassium metabisulfite is a preservative made from potassium hydroxide and sulfur dioxide. They are often used together in food production.

These ingredients act as preservatives, preventing spoilage from bacteria, molds, and yeasts. They are commonly found in alcoholic beverages like wine and wine coolers, as well as some dried fruits and processed foods.

Potassium benzoate and potassium metabisulfite are permitted food additives in the US. The FDA lists potassium benzoate as GRAS (Generally Recognized As Safe) when used according to good manufacturing practices. Potassium metabisulfite is approved by the FDA as a preservative and antioxidant. Both have been evaluated by international bodies like JECFA and EFSA. While generally considered safe at typical levels, some individuals may be sensitive to sulfites, experiencing reactions like asthma symptoms.
