中文摘要:该文研究了制丝线增温增湿和滚筒烘丝工序加工对叶丝香味组分的影响,采用溶剂超声萃取前处理结合GC-MS法测定叶丝的香味组分,并对SIROX增温增湿工序和滚筒烘丝工序前后叶丝香味组分的相对含量进行了分析,比较了工序前后、工序间香味组分的变化趋势。结果显示:①经SIROX增温增湿工序加工后,乙酸、苯甲醇等18种组分相对含量减少,糠醇、2,4-二羟基-2,5-二甲基-3(2H)-呋喃-3-酮等6种组分相对含量增加;②经滚筒烘丝工序加工后,乙酸、麦芽酚等14种组分相对含量减少,糠醇、糠醛等6种组分相对含量增加;③经增温增湿及滚筒烘丝两工序后,乙酸、2,3-丁二醇等23种组分相对含量减少,糠醇、2,4-二羟基-2,5-二甲基-3(2H)-呋喃-3-酮等4种组分相对含量增加;④两工序间的温度、湿度剧烈变化,使叶丝内部组分发生了美拉德反应、降解反应、挥发等,香味组分经两个工序后发生了一系列显著变化。该研究对提升卷烟产品质量、优化工艺参数、开发高质量产品具有重要意义。

Investigation on Variation of Aroma Components in Cut Tobacco in Heating and Humidifying Process and Drying Process of Primary Processing Line
Abstract:In order to investigate the variation of aroma components in cut tobacco in the heating and humidifying process(SIROX process) and drying process on primary processing line,samples were collected on the primary processing line at three time points:before SIROX,after SIROX(before drying) and after drying.Samples were ultrasonically extracted with solvent,then analyzed by GC-MS and quantified with C17 as internal standard.Results showed that:Firstly,the contents of 18 aroma components such as acetic acid and benzyl alcohol,etc.decreased during SIROX process,while those of 6 aroma components increased,including 2-furanmethanol,2,4-dihydroxy-2,5-dimethyl-3(2H)-furan-3-one,etc.Secondly,the contents of 14 aroma components such as acetic acid and maltol,etc.decreased during drying process,while those of 6 aroma components increased,including 2-furanmethanol and 2-furancarboxaldehyde,etc.Thirdly,the contents of 23 aroma components such as acetic acid and 2,3-butanediol,etc.decreased during SIROX and drying process,while those of 4 aroma components increased,including 2-furanmethanol and 2,4-dihydroxy-2,5-dimethyl-3(2H)-furan-3-one,etc.Fourthly,the variations of temperature and humility in SIROX and drying process on primary processing line may result in Maillard reaction,degradation and volatilization inside the cut tobacco,leading to the changes of the aroma components.This investigation provides a scientific basis for the development of cigarette products with high quality.
