General review of Lecithin

Lecithin is also known as phosphatidylcholine, which consists of choline, together with inositol, phosphoric acid, glycerol, glycolipids, and linoleic acid. Lecithin is very essential in the cells of the body for key recovery of cell membranes and preventive purpose. It is a very cheap source of choline. Commercial lecithin usually obtained as a by-product in the production of soybean oil and sold as soy lecithin. This lecithin is often used by supplements for vegetarians (who do not naturally get enough choline in their diet), medicines production, cosmetics production as well as food industries as food additives or emulsifiers to allow the combination of oils and water during ice cream, margarine, mayonnaise, peanut butter and chocolate production. It is excellent emulsifier to mix the oil and water together and avoid separation happen. When lecithin is added, it will break down the oil into smaller particles. This is how emulsification happens. Lecithin can also help to improve the products’ appearance and consistency as well as extend shelf life. Thus, it is considered as valuable things in food industries
