Calcium Propionate & Citric Acid

Calcium propionate is a calcium salt of propionic acid. Propionic acid is a naturally occurring compound produced by fermentation, but for food use, it is typically manufactured synthetically. Citric acid is a weak organic acid found naturally in citrus fruits like lemons and limes, but it is usually produced commercially through the fermentation of sugar by specific molds.

Calcium propionate and citric acid are often used together in baked goods. Calcium propionate acts as a preservative, inhibiting the growth of mold and bacteria, which extends shelf life. Citric acid can function as an acidity regulator, flavor enhancer, and antioxidant, helping to maintain the product's color and taste.

Both calcium propionate and citric acid are generally recognized as safe (GRAS) by the FDA for use in food. They are commonly consumed in baked goods and other processed foods. International bodies like JECFA have evaluated these substances. While generally considered safe, some individuals may experience sensitivities.
