They mostly exist in a combined form in organisms. The main function and effect of fatty acids is to provide energy and store energy. They are one of the sources of energy for the body. In addition, fatty acids are also widely used in industrial production, such as the manufacture of daily cosmetics, detergents, industrial fatty acid salts, coatings, paints, rubber, soaps, etc.
[0003] Fatty acid capture equipment is a kind of equipment used in the deacidification and deodorization process of oil refining.
