水蒸气蒸馏和超临界CO₂萃取橘皮精油及应用

摘要: 采用超临界CO₂萃取和水蒸气蒸馏法提取橘皮精油,对两种精油进行了GC/MS测定,并将两种精油用于卷烟加香实验。结果表明:①超临界CO₂萃取的橘皮精油得率为0.67%,检测出76种香气成分,主要有D-柠檬烯(91.88%)、γ-松油烯(2.23%)、β-月桂烯(1.59%)、α-蒎烯(0.89%)等;②水蒸气蒸馏橘皮精油的得率为0.29%,检测出27种香气成分,主要有D-柠檬烯(84.05%)、柠檬烯氧化物(2.23%)、β-月桂烯(0.88%)、α-蒎烯(0.85%)等;③超临界萃取橘皮精油在改善卷烟香气的丰富性、提高香气质感方面好于水蒸气蒸馏法精油。

Abstract: Essential oils extracted from orange peel by supercritical CO₂ extraction and steam distillation were determined by GC/MS and applied as cigarette flavoring separately. The results showed that: 1) The yield of essential oil from supercritical CO₂ extraction was 0.67%, and 76 aroma components, including D-limonene (91.88%), γ-terpinene (2.23%), β-myrcene (1.59%), and α-pinene (0.89%), were detected in the oil. 2) The yield of essential oil extracted by steam distillation was 0.29%, and 27 aroma components, including D-limonene (84.05%), D-limonene oxide (2.23%), β-myrcene (0.88%), α-pinene (0.85%), were identified in the oil. 3) The oil from supercritical CO₂ extraction was better than that from steam distillation in improving aroma abundance and aroma quality of cigarette.
