摘要：

为研究薄板干燥工序中不同含水率对同一规格不同批次卷烟试样烟丝样品中致香物质的组成及含量的影响，建立静态顶空-气相色谱质谱（HS-GC/MS）联用法，以乙酸-2-苯乙酯为内标，MES自动控制系统采集数据，结合NIST和WILEY谱库检索定性、内标定量，对国内市售卷烟品牌R的两个不同批次（E、F）样品中致香成分进行测定。两个批次的成品烟丝共检测出41种核心致香成分，其中批次E含39种，批次F含37种；6-甲基-3，5-庚二烯-2-酮、六氢金合欢基丙酮为E中未检出的成分，2-（2-戊烯基）呋喃、氧化异佛尔酮、二氢猕猴桃内酯和苯乙烯为F中未检出的成分；E中的致香物质相对总含量小于样品F中的致香物质相对总含量，将薄板干燥工序烟丝含水率控制在14%有利于保留烟丝中的致香成分。静态顶空结合MES系统可以快速准确对样品进行分析测定，条件温和，操作简单，数据获取自动化、智能化，有利于提高生产质量，在烟草行业的生产制造方面具有积极影响。

Abstract: To study the effects of different moisture content on the composition and content of aroma components in test samples of different batches of cigarettes of the same specification. A static headspace-gas chromatography-mass spectrometry (HS-GC/MS) method was established. The reaction was performed with-2-ethyl acetate as the internal standard. The data was collected by the MES automatic control system. The NIST and WILY libraries were used to search the qualitative and internal standards. Quantitatively, the aroma components in two different batches (E, F) of the domestic commercial cigarette brand R were measured. Atotal of 41 core aroma components were detected in two batches of finished cut tobacco, of which batch E contained 39 and batch F contained 37; 6-methyl-3,5-heptadien-2-one, Hexahydrofarnesyl acetone are undetected components in E, 2-(2-pentenyl) furan, isofordone oxide, dihydroactinidioli and styrene are undetected components in F; the relative total content of aroma substances in E is less than the relative total content of aroma substances in sample F, and controlling the moisture content of the drying process of thin plate at 14% is favorable to keep the aroma components in the tobacco. The static headspace combined with MES system can quickly and accurately analyze and determine samples. The conditions are mild, the operation is simple, the data acquisition is automated, intelligent, and it is conducive to improving production quality. It has a positive impact on the manufacturing of the tobacco industry.
