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.
