麦芽精油成分研究及其在卷烟中应用

采用水蒸气蒸馏法提取普通麦芽、炒麦芽和焦香麦芽的精油组分，通过GC-MS方法分析不同麦芽精油的主要化学成分，并对制备出的精油进行了卷烟添加实验。结果表明:不同麦芽的精油中均含有棕榈酸及其酯类，但其他化学成分差异较大，造成了它们在卷烟中不同添加效果。焦香麦芽精油中含有大量的吡嗪类化合物、糠醛类衍生物和麦芽酚，加入到卷烟中表现出突出的焦甜香韵，是较好的焦甜香香原料。 

Study of Essential Oil in Malt and its Application in Cigarette

Essential oil was extracted from common malt, torrefied malt and caramel malt by stem distillation method. The components of essential oil were studied by GC-MS and compared, and then followed by addition into cigarettes to estimate their function. The results showed that cetylic acid and cetylate were found in all kinds of essential oil, but other components differed greatly. These differences caused the diversity of additive effect. The essential oil extracted from caramel malt contained plenty of pyrazine compounds, furfural derivatives and maltol, and showed obviously camarel note when added into cigarettes.
