摘要
为探究不同挤压处理条件对加热卷烟用烤烟烟叶化学组分和主要香气成分的影响,以下部烤烟叶为原材料,采用连续流动分析法、高效液相色谱法、气相色谱-离子迁移谱(GC-IMS)等方法,分析不同挤压处理条件下烤烟烟叶化学组分和主要香气成分的差异。结果表明:不同温度挤压处理显著(P<0.05)影响烤烟烟叶的水溶性糖、还原糖、总氮等常规化学组分的含量。140℃挤压处理后的烤烟烟叶的总酚含量[(116.30±1.24)mg·g^(-1)]较烤烟原叶[(109.25±0.93)mg·g^(-1)]显著增加。不同挤压处理组的烤烟烟叶与烤烟原叶的风味物质含量存在差异,特别是140℃、160℃挤压处理下烟叶的苯乙酸乙酯、2-糠醛等组分的含量升高,而异丁酸、异戊醇等的含量降低,这些变化增强了烤烟中的焦糖味甜香,可起到丰满烟气风味的作用。
In order to investigate the effects of different extrusion treatments on the chemical composition and main aroma components of flue-cured tobacco leaves for heat-not-burn cigarettes,flue-cured tobacco leaves were selected as raw materials,and the chemical components as well as the main aroma components under different extrusion treatments were analyzed via continuous flow analysis,high performance liquid chromatography(HPLC),and gas chromatography-ion mobility spectroscopy(GC-IMS),etc.Results indicated that the contents of water-soluble sugar,reducing sugar,total nitrogen and other conventional chemical components were significantly(P<0.05)affected by the extrusion treatments.Compared with the leaves before treatment[(109.25±0.93)mg·g^(-1)],the total phenolic content of flue-cured tobacco leaves after extrusion treatment at 140℃[(116.30±1.24)mg·g^(-1)]was significantly increased.Differences in the content of flavor substances were observed between the flue-cured tobacco leaves before and after the extrusion treatments.The relative content of ethyl phenylacetate and 2-furfural in the extrusion treatment group at 140℃and 160℃increased,while the content of isobutyric acid,isoamyl alcohol decreased,which enhanced the caramel flavor in flue-cured tobacco and thus played the role of plumping smoke flavor.
