摘要
采用超临界流体萃取技术对云南烤烟的香味物质进行萃取.结果表明,超临界二氧化碳萃取烟草香味成分的最佳工艺条件为:压力20 MPa,温度50℃,CO2流量7 kg/h,萃取时间4 h,此时萃取率可达2.9%.
Isolation of the flavor components in flue-cured from Yunnan was studied by using supercritical fluid extraction methods, The results showed that the optimal conditions were working pressure was 20 MPa, temperature was 50 ℃. carbon dioxide flow was 7 kg/h, operating time was 4 h. Under these conditions the extraction yield was 2.9%.
