无溶剂微波萃取红大烟叶精油

Solvent-free microwave extraction of essential oil from Hongda tobacco leaf

通过绿色无溶剂微波萃取技术提取云南优质烟草品种红花大金元(简称红大)烟叶中的精油,采用GC/MS分析精油的挥发性致香成分及其百分含量,并对比分析其与市售红大精油的挥发性成分的异同。在某品牌加料丝上加香后的感官评吸结果表明,无溶剂微波萃取所得精油能有效增加烟草本香、丰富烟香、提升浓度、减低刺激、掩盖杂气,抽吸效果优于市售红大精油。

The tobacco essential oil of high quality tobacco leaf named Honghua Dajinyuan (Hongda for short) in Yunnan was extracted via green solvent-free microwave extraction (SFME).The volatile aroma substances and their percentages of both the tobacco essential oil and commercially available Hongda absolute oil were detected respectively through GC/MS analysis,and the data were compared in the similarities and differences.These two tobacco oils were flavored to cigarettes and then valuated by smoking.The result shows that the tobacco essential oil by SFME can not only enhance and enrich the tobacco aroma but also reduce the irritancy and cover up the odor.The essential oil is superior to Hongda absolute oil on smoking feelings.
