摘要
为了快速高效地萃取烟草香味成分,进行了烟草香味成分的超高压萃取(UHPE)试验,并利用响应面分析法对萃取参数进行了优化。结果表明:烟草香味成分的最优UHPE条件为萃取压力380MPa、保压时间20min、萃取溶剂75%乙醇,液料比15,在此条件下,香味成分萃取总量理论值180.9μg/g,验证值179.8μg/g。
In order to extract aroma constituents in tobacco quickly and efficiently, the experiments on the extraction of aroma constituents in tobacco with ultra high pressure extraction （UHPE） were conducted and the extracting conditions were optimized with response surface extraction conditions were： pressure 380 MPa （20 minutes tobacco 15. The total yield of aroma constituents was 180. methodology. The results showed that the optimal ） , solvent 75% ethanol, and the ratio of solvent to 9 μg/g （theoretical） or 179.8 μg/g （actual）
