E202 And Sodium Metabisulphite

Potassium sorbate (E202) is a salt of sorbic acid, a naturally occurring compound found in some fruits. It is manufactured industrially by reacting potassium hydroxide with sorbic acid. Sodium metabisulfite is a white crystalline powder used as a preservative and antioxidant.

Potassium sorbate and sodium metabisulfite are commonly used together as preservatives in a wide variety of foods, including pickles, olives, and relishes. They help prevent the growth of mold, yeast, and bacteria, extending the shelf life of products. They are often found in acidic foods where they are most effective.

Both potassium sorbate and sodium metabisulfite are permitted food additives in the US. Potassium sorbate is Generally Recognized As Safe (GRAS) by the FDA. Sodium metabisulfite is permitted as a preservative and antioxidant. JECFA and EFSA have evaluated both substances. Some individuals may experience sensitivity to sulfites, including sodium metabisulfite, which can cause allergic-type reactions, particularly in those with asthma.
