Abstract: In order to compare and analyze the quality of Camellia oil extracted by aqueous enzymatic extraction, aqueous extraction and organic solvent extraction, physicochemical indexes of extracted lipids were analyzed, as squalene and vitamin E (VE) contents, and fatty acid composition were determined by chemical analysis, HPLC and GC-MS methods. It was shown that the sensory and physicochemical index of Camellia oil extracted by aqueous enzymatic extraction and aqueous extraction was similar, and was better than that extracted by organic solvent. The contents of squalene and α-,β-,δ-VE in Camellia oil extracted by aqueous enzymatic extraction were 255.00, 247.44, 46.05, 11.65 μg·g-1, respectively, and were higher than those extracted by other methods. In general, aqueous enzymatic method was superior for Camellia oil extraction to other methods in term of sensory quality, physicochemical index as well as the content of functional material (squalene and VE), and thus possessed greater potential for industrial implication.
