E470b - Sels de magnésium d'acides gras

Origin

E470b, Magnesium salts of fatty acids, are metallic soaps derived from edible fats and oils. These salts are formed by reacting fatty acids, typically obtained from vegetable or animal sources, with magnesium oxide or magnesium hydroxide. The resulting product is a mixture of magnesium salts of various fatty acids, such as stearic, palmitic, and oleic acids. The composition depends on the source of the fatty acids used.

Usage

Magnesium salts of fatty acids are primarily used as anti-caking agents, emulsifiers, and stabilizers in a variety of food products. They prevent powders from clumping together, ensuring a free-flowing consistency. They are also used as release agents in confectionery and baking, preventing products from sticking to molds or equipment. Additionally, E470b can act as a carrier for other additives, improving their dispersion and effectiveness. Common applications include powdered foods, spices, bakery products, confectionery, and dietary supplements. In the pharmaceutical industry, they are used as lubricants in tablet manufacturing.

Side Effects

Magnesium salts of fatty acids are generally considered safe for consumption. They are poorly absorbed in the gastrointestinal tract, and any absorbed magnesium is readily excreted by the kidneys. No significant adverse effects have been reported in human studies at levels typically used in food. However, excessive consumption of magnesium from any source can potentially lead to mild laxative effects in some individuals.

Regulatory Status

E470b is approved for use as a food additive in the European Union (EU) and is subject to specific purity criteria. The European Food Safety Authority (EFSA) has evaluated the safety of E470b and has concluded that it does not pose a significant health risk at current levels of use. It is also permitted for use in food in many other countries, including the United States, where it is generally recognized as safe (GRAS) under certain conditions of use. There is no specific ADI (Acceptable Daily Intake) established for E470b, as it is considered to be of low toxicity.
