The main use of fats and oils in the feed industry is however increasing the energy content of the feed economically. They are insoluble in water. other industrial purposes. Biosystems engineering integrates engineering science and design with applied biological, environmental, and agricultural sciences. Description. Fats and oils predominantly are triesters (triglycerides, triacylglycerols, TAG) of glycerol and aliphatic fatty acids containing up to 22 carbon atoms.Waxes are esters of long-chain fatty acids, usually containing 24-28 carbon atoms, with long-chain primary alcohols (16-36 carbon atoms) or with alcohols of the steroid group []. Radical reactions typically have three steps: 1. AOCS RESOURCE. 1.19. In addition, the availability of fats can be limited due to legislation, religious prohibitions, or trade barriers.
