What it is
Preservative enzymes are enzymes used to extend the shelf life of food. They are typically proteins produced by microorganisms like bacteria or fungi through fermentation. These enzymes work by targeting specific spoilage mechanisms in food, such as the breakdown of carbohydrates or the formation of undesirable byproducts.
Why it's used
Manufacturers add preservative enzymes to inhibit the growth of spoilage microorganisms or to prevent undesirable chemical reactions that can degrade food quality. They are often found in baked goods like cakes, cupcakes, and snack cakes, where they can help maintain freshness and texture.
Health notes
Preservative enzymes are generally recognized as safe (GRAS) by the FDA for their intended use in food. They are proteins that are digested like other food proteins and are not expected to pose health risks at the levels typically consumed. International bodies like JECFA have evaluated enzymes used in food processing, and their use is subject to regulatory oversight.
Allergen info
Preservative enzymes are not derived from any of the 9 FDA major allergens. They do not contain gluten.
