Calcium Propionate And Sorbic Acid To Extend Freshness

Calcium propionate and sorbic acid are antimicrobial preservatives used together to prevent the growth of mold and bacteria in foods. Calcium propionate is a salt of propionic acid, which occurs naturally in some foods and is produced industrially. Sorbic acid is a naturally occurring organic compound, also produced synthetically for food use.

These ingredients are added to extend the shelf life and maintain the freshness of baked goods, particularly breads and rolls. They work by inhibiting the growth of microorganisms that can cause spoilage, ensuring the product remains safe and appealing for longer periods.

In the U.S., both calcium propionate and sorbic acid are generally recognized as safe (GRAS) by the FDA when used as preservatives. International bodies like JECFA and EFSA have also evaluated these substances. While generally considered safe at typical consumption levels, some individuals may report sensitivities or adverse reactions, though scientific evidence for widespread negative effects at normal intake is limited.
