摘要: 采用固相微萃取-气质联用法对鲜榨锦橙汁的香气成分进行分析,并比较不同萃取头对鲜榨橙汁香气成分的萃取差异。结果表明:从鲜榨橙汁中共鉴定出53种香气成分,包括烯烃类、酯类、醇类、醛类和酮类,其中的主要香气化合物为柠檬烯、β-月桂烯、芳樟醇、α-松油醇、4-松油烯醇、丁酸乙酯、辛醛、α-蒎烯、β-水芹烯等物质。

Abstract: The aromatic composition of fresh glorious orange juice was analyzed by solid phase microextraction (SPME) coupled with gas chromatography-mass spectroscopy (GC-MS). The difference in aromatic component among fresh orange juices extracted by different SPME fibers was compared. Results indicated that 53 kinds of aromatic components including hydrocarbons, esters, alcohols, aldehydes and ketones were identified. The major aromatic components in fresh orange juice were limonene, β-myrcene, linalool, α-terpineol, terpinen-4-ol, ethyl butyrate, octanal, α-pinene and β-phellandrene.

Key words: fresh orange juice, solid phase microextraction, GC-MS, aromatic composition
