What it is

Propionic acid is a naturally occurring organic acid found in some foods, like Swiss cheese. It is typically produced industrially through the carbonylation of ethylene. Phosphoric acid is a mineral acid, commonly produced from phosphate rock.

Why it's used

Propionic acid and its salts are used as preservatives to prevent mold growth in baked goods and other foods. Phosphoric acid is used as an acidity regulator, flavor enhancer, and preservative in beverages, particularly colas, and other processed foods.

Health notes

Propionic acid is generally recognized as safe (GRAS) by the FDA for use as a food additive. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated propionic acid and its salts. Phosphoric acid is also GRAS for use in food. JECFA has evaluated phosphoric acid and its salts. Some research has explored the role of propionic acid in human metabolism, but its effects at typical dietary intake levels are considered safe.

Allergen info

Neither propionic acid nor phosphoric acid are derived from or are one of the FDA's 9 major allergens. They do not contain gluten.
