Abstract
A simple method has been successfully applied to extract squalene and its byproducts alkoxyglycerol from deep-sea shark liver oil. GC-MS was used to determine the extraction amount of the squalene and alkoxyglycerol, and the content of them in rough product and refined product were compared. The physical property of squalene was identified by measuring the pH value, peroxide value and iodine value. Under optimum extraction conditions, the amount of squalene and alkoxyglycerol increased 35.0% and 21.9%, respectively, while the amount of fatty acid decreased from 61% to 4%, especially, the amount of palmitic acid and oleic acid remarkably decreased. Large amount of peroxide and acid were removed from shark liver oil after refining process. Because squalene contains lots of double bond, so the value of iodine is much higher than squalane.
