摘要
【目的】研究成品烟丝致香成分与不同碳化温度间的关系。【方法】设计制作相同的成品烟丝样品,通过HS-GC-MS在不同碳化温度条件下(80、100和120℃)测定烟丝致香成分的种类,并研究两者间的相互影响。【结果】(1)成品烟丝从80℃开始碳化,120℃时碳化明显,从低温到高温,色泽由金黄色向棕褐色转变。(2)在80、100和120℃各温度条件下,平行测试的质谱峰形态基本表现一致,分别检测到18、52和81种致香成分,分子量范围为44.026~241.077 u。(3)从低温到高温,不同碳化温度下特征致香物质的数量分别为4、13和36种。【结论】随着温度的提升,致香成分的数量不断增加,其中,100℃时特征致香成分为胺类、醇类、硫化物和含氧多环类化合物,分子量40~200 u;120℃时特征致香成分为酮类、醇类、醚类和含氮多环化合物,分子量50~160 u。
[Purposes]To study the relationship between the aroma components and the different carbonation temperatures.[Methods]The same finished tobacco samples were designed and manufactured.The types of aroma components were determined by HS-GC-MS at different carbonation temperatures(80,100 and 120℃),and the interaction between them was studied.[Results](1)The finished tobacco was carbonized from 80℃,and the carbonization was obvious at 120℃.From low temperature to high temperature,the color changed from golden to brown.(2)At 80,100 and 120℃,the mass spectra of the parallel test were basically the same,and 18,52 and 81 aroma components were detected.The molecular weight range was 44.026?241.077 u.(3)From low temperature to high temperature,the number of fragrant substances in different carbonation temperature was 4,13 and 36 species respectively.[Conclusions]With the increase of temperature,the number of incense components is increasing.Among them,at 100℃,the characteristic aroma components included amines,alcohols and sulfides,oxygen-containing polycyclic compounds and the molecular weight ranged 40 from 200 u;at 120℃,ketones,alcohols,ethers and nitrogen-containing polycyclic compounds and the molecular weight ranged 50 from 160 u.
