摘要
Abstract
The essential oils extracted from laurel leaf with three methods (supercritical CO2 extraction, subcritical CO2 extraction and steam distillation) were added into cigarettes as a flavor separately. The chemical components in the essential oils were analyzed by GC/MS, and the technical parameters in supercritical and subcritical CO2 extraction were optimized with orthogonal experiments. The results showed that: 1) The yield of essential oil reached 2.37% under the optimized parameters of supercritical CO2 extraction, 55 ℃, 30 MPa, extracting for 1 hour; the yield of essential oil was 2.16% under the optimized parameters of subcritical CO2 extraction, 15 ℃, 20 MPa, extracting for 1 hour. The yield of essential oil extracted by steam distillation was 1.25%. 2)66, 62 and 49 aroma components were identified in the essential oils obtained by supercritical, subcritical CO2 extraction and steam distillation, respectively;the major components were 1,8-cineole, α-terpinyl acetate, linalool, their proportions in the essential oils by supercritical CO2 extraction were 16.43%, 15.68%, 12.84%; by subcritical CO2 extraction were 17.22%, 16.11%, 11.84%; and by steam distillation were 18.39%, 15.60%, 9.60%, respectively. 3)The essential oil obtained by supercritical CO2 extraction were comparable to that by subcritical CO2 extraction, and were superior to that by steam distillation in terms of improving aroma quality and aftertaste and reducing irritancy of cigarette smoke.关键词
