What it is
Propionic acid is a naturally occurring organic acid produced by fermentation. Phosphoric acid is a mineral acid. When used together, they often function as a preservative system.
Why it's used
This combination is used to inhibit mold and bacterial growth in baked goods like cakes, cupcakes, snack cakes, breads, and buns, extending their shelf life. They can also contribute to the overall flavor profile and act as acidity regulators.
Health notes
Propionic acid and its salts are generally recognized as safe (GRAS) by the FDA for use as preservatives. Phosphoric acid is also GRAS and approved as a food additive. Both have been evaluated by JECFA and EFSA. At typical consumption levels found in food, they are not associated with adverse health effects.
Allergen info
Neither propionic acid nor phosphoric acid are among the FDA's major food allergens. They do not contain gluten.
