摘要: 采用化学分析法、HPLC、GC-MS法分析水酶法、水代溶剂法、有机溶剂萃取法所得山茶油的理化指标、角鲨烯、维生素E、主要脂肪酸含量及组成。结果显示,水酶法和水代溶剂法提取山茶油的感官指标和理化指标相近,优于有机溶剂萃取法所提山茶油。水酶法所提山茶油中的角鲨烯(255.00 μg·g-1)、α-维生素E(247.44 μg·g-1)、β-维生素E(46.05 μg·g-1)、δ-维生素E(11.65 μg·g-1)含量高于其他2种方法所提山茶油。各方法提取的山茶油中脂肪酸组成没有显著性差异。从感官、理化指标和特征活性物质角鲨烯及维生素E含量综合来看,水酶法提取山茶油的品质较优,在工业生产中具有较大的应用前景。

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.
