Origin
E 470a is obtained from natural plant or animal fats, which are mixed with lye in a chemical process. In industrial production, rapeseed oil, corn oil, or soybean oil are typically used.
Usage
Fatty acid salts have the property of finely distributing water- or fat-soluble substances in an emulsion of fat and water, thus creating a homogeneous liquid. E 470a is permitted for use in food without any maximum quantity restrictions. The food additive E 470a is often found in the following products: baked goods, chewing gum, confectionery, sugar cubes, and also sweetener tablets.
Risks
E 470a is considered a completely harmless food additive. Fatty acid salts are metabolized like fats by the human organism. An ADI value (Acceptable Daily Intake), i.e., a recommended daily dose has not been established.
