E470a - Sodium/potassium and calcium salts of fatty acids

Origin

E470a, also known as sodium, potassium, and calcium salts of fatty acids, are derived from edible fats and oils, either of vegetable or animal origin. These salts are produced through the saponification process, where triglycerides (fats and oils) are reacted with sodium, potassium, or calcium hydroxide. The resulting products are mixtures of sodium, potassium, or calcium salts of various fatty acids, such as stearic, palmitic, and oleic acids. The specific composition depends on the source of the fats and oils used.

Usage

E470a functions primarily as an emulsifier, stabilizer, and anti-caking agent in food products. It helps to improve the texture and consistency of foods, prevent the separation of oil and water phases, and ensure that powdered products flow freely. It is commonly used in baked goods, confectionery, dairy products, processed fruits and vegetables, and dietary supplements. In some applications, it can also act as a release agent, preventing food from sticking to processing equipment.

Side Effects

E470a is generally considered safe for consumption. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) 'not specified', indicating that, based on available data, the intake of E470a at levels necessary to achieve the desired technological effect does not pose a health risk. However, as with any food additive, excessive consumption may lead to gastrointestinal discomfort in sensitive individuals. No significant adverse health effects have been reported in relation to the consumption of E470a at levels typically found in food.

Regulatory Status

E470a is permitted for use as a food additive in many countries, including those in the European Union, the United States, and Canada. It is subject to regulatory standards that specify its purity and conditions of use. In the EU, E470a is listed in Annex II of Regulation (EC) No 1333/2008 as a food additive that may be added to food. The FDA in the US considers it as GRAS (Generally Recognized As Safe) when used in accordance with good manufacturing practices.
