E470a

E470a is the European Union designation for the salts of fatty acids. These are commonly known as soaps. Specifically, E470a refers to the sodium, potassium, and calcium salts of fatty acids. These are derived from edible fats and oils, which can be of animal or vegetable origin.

In the food industry, E470a functions primarily as an emulsifier, anti-caking agent, and stabilizer. Emulsifiers help to blend ingredients that would normally separate, such as oil and water. Anti-caking agents prevent powdered or granulated foods from clumping together, ensuring a free-flowing texture. As stabilizers, they help maintain the consistency and texture of food products.

These substances are produced by the saponification of fats and oils, a process involving reaction with a strong alkali. The resulting salts are typically white or yellowish powders. E470a is permitted for use in a wide range of food categories, including baked goods, dairy products, confectionery, and processed meats. They are considered safe for consumption and are regulated by food safety authorities in the EU and other regions. Their presence in food products is indicated on ingredient labels by the E number E470a or by their chemical name.
