Conservator

A conservator is a substance added to food to prevent spoilage and extend shelf life. It works by inhibiting the growth of microorganisms like bacteria, yeasts, and molds. Common conservators include sorbic acid, benzoic acid, and their salts.

Manufacturers add conservators to prevent spoilage and maintain the quality of foods. They are often found in products with a high water content and a pH that can support microbial growth, such as jams, jellies, fruit spreads, baked goods, and beverages.

In the U.S., common conservators like sorbic acid and benzoic acid are generally recognized as safe (GRAS) by the FDA when used as intended. International bodies like JECFA have evaluated these substances and established acceptable daily intakes. While generally safe at typical consumption levels, some individuals may experience sensitivities or allergic reactions, though this is rare.
