Comparing quality of camellia oil extracted by different methods

According to sensory index,physicochemical index and some active components content of camellia oil,the quality of camellia oil extracted by different methods as aqueous enzymatic extraction,aqueous extraction,pressing process,supercritical CO2 extraction and organic solvent lixiviation process was compared.The results showed that the sensory and physicochemical index of camellia oil extracted by aqueous enzymatic and aqueous process was similarity and better than that extracted by other ways.The VE in camellia oil was nearly all α-VE.The oil by pressing has highest squalene content and lowest VE content,and the oil of supercritical process has highest VE content.The squalene content and VE content of camellia oil extracted by aqueous enzymatic,aqueous,solvent extraction were similar.The fatty acids composition of camellia oil extracted by all these methods had no significant differences.
