E282 – Calcium Propionate
PreservativeDescription
Calcium salt of propionic acid, white crystalline powder
Notes
Calcium propionate is made by combining propionic acid (a naturally occurring organic acid found in dairy products) with calcium carbonate or calcium hydroxide. This process creates white, odorless crystals that dissolve easily in water. Think of it as the calcium salt version of propionic acid – like how table salt is the sodium version of chlorine, but much more food-friendly. This additive serves as a mold-fighting preservative, helping to keep bread and baked goods fresh for longer periods. You'll find it most commonly in commercially produced bread, rolls, buns, and other baked products where it prevents the growth of rope bacteria (which makes bread stringy and smelly) and various molds. It's especially popular in the baking industry because it doesn't affect the taste, texture, or rise of bread dough. Calcium propionate is considered a synthetic additive, though it's made from components that occur naturally. It's suitable for vegetarian and vegan diets, and there are no restrictions under most religious dietary laws. As a bonus, it actually provides a small amount of calcium to your diet. Food safety authorities worldwide consider it safe for consumption, and it's been used in commercial baking for many decades without significant health concerns.
