Edible Oils #7667010

after milling, various palm oil products are made using refining processes. First is fractionation, with crystallization and separation processes to obtain solid (stearin), and liquid (olein) fractions. Then melting and degumming removes impurities. Then the oil is filtered and bleached.

The oil is then refined, blended for different applications, and sometimes hydrogenated. Soybean oils, both liquid and partially hydrogenated are sold as "vegetable oil, " or are ingredients in a wide variety of processed foods. Most of the remaining residue (soybean meal) is used as animal feed.

Canola oil, or canola for short, is a vegetable oil derived from rapeseed that is low in erucic acid, as opposed to colza oil.Canola oil is made at a processing facility by slightly heating and then crushing the seed. Almost all commercial canola oil is then extracted using hexane solvent[21] which is recovered at the end of processing. Finally, the canola oil is refined using water precipitation and organic acid to remove gums and free fatty acids, filtering to remove color, and deodorizing using steam distillation. The average density of canola oil is 0.92 gml.
