Soybean oil, a vegetable oil extracted from the seeds of the soybean (Glycine max), has an oil content accounting for around 22% of the dry seed. Soybeans are the biggest source of edible oil in the world. The high polyunsaturated fatty acid content (over 60%, including 6–10% α-linolenic acid) in soybean oil makes it very attractive, as it meets our requirement for essential fatty acid.
Crude Degummed Soybean Oil (CDSO) is produced from crude soybean oil by removing the majority of free fatty acids and gums which are naturally present in soybeans. Free fatty acids and gums (phospholipids) are removed by hydration and mechanical or physical separation.
