Potassium Sorbate And Sodium Bisulfite To Maintain Freshness

Potassium sorbate is a salt of sorbic acid, a naturally occurring compound found in some plants. It is typically produced industrially by reacting sorbic acid with potassium hydroxide. Sodium bisulfite is a salt of sulfurous acid, often produced from sulfur dioxide and sodium hydroxide or carbonate.

These ingredients are added to foods as preservatives to inhibit the growth of mold, yeast, and bacteria, helping to maintain freshness and extend shelf life. They are commonly found in sauces, dried fruits, baked goods, and dairy products.

Potassium sorbate and sodium bisulfite are permitted food additives in the U.S. Sodium bisulfite is generally recognized as safe (GRAS) by the FDA. Potassium sorbate is also approved by the FDA. Both have been evaluated by international bodies like JECFA and EFSA. Sodium bisulfite can cause allergic-type reactions in sensitive individuals, particularly those with asthma. High intake of sulfites can lead to adverse effects in some people.
