Potassium Sorbate & Sodium Metabisulfite

Potassium sorbate is the potassium salt of sorbic acid, a naturally occurring compound found in some plants. It is manufactured industrially through a chemical process. Sodium metabisulfite is a white crystalline powder made from sulfur dioxide.

These ingredients are primarily used as preservatives to inhibit the growth of mold, yeast, and bacteria in foods. They help extend shelf life and maintain product quality. They are often found in dried fruits, wine, baked goods, and some processed cheeses.

Potassium sorbate is generally recognized as safe (GRAS) by the FDA. Sodium metabisulfite is also permitted by the FDA as a food additive. Both have been evaluated by EFSA and JECFA. While generally considered safe at typical levels, some individuals may experience sensitivity or allergic-type reactions, particularly to sulfites like sodium metabisulfite, which can trigger asthma symptoms in sensitive people.
