Calcium Propionate And Potassium Sorbate

Calcium propionate and potassium sorbate are salts of propionic acid and sorbic acid, respectively. These acids are naturally found in some foods, but the salts used in food production are typically made synthetically. They are commonly used together as antimicrobial agents to prevent spoilage.

Manufacturers add calcium propionate and potassium sorbate to inhibit the growth of mold, yeast, and bacteria, thereby extending the shelf life of baked goods and other processed foods. They are frequently found in breads, cakes, pastries, and other bakery items where mold growth is a concern.

In the United States, both calcium propionate and potassium sorbate are Generally Recognized As Safe (GRAS) by the FDA for use as food additives. These substances have been evaluated by international bodies like JECFA and EFSA, which have established acceptable daily intake levels. At the levels typically consumed in food, they are not associated with adverse health effects for most people. Some studies have explored potential links to behavioral issues in children, but the evidence is mixed and not conclusive.
