摘 要:以2009年收集的84份C3F烟样为材料,研究了浓香型、清香型和中间香型烟叶致香物质组成比例及其差异。结果表明:清香型烟叶中棕色化反应降解产物极显著高于其他香型,新植二烯显著或极显著低于其他香型,中间香型烟叶中苯丙氨酸类降解产物、类西柏烷类降解产物的组成比例极显著低于其他香型。

Abstract: Aroma component proportion and their differences among enriched, clear, and intermediate in ?ue-cured tobacco were studied with 84 leaf samples (C3F) from main tobacco planting regions in 2009. Results showed that signi?cant or extremely signi?cant differences existed in some aroma components proportion among aroma styles. In general, clear aroma tobacco had signi?cantly higher proportion of Maillard reaction products, and signi?cant or extremely signi?cant lower proportion of Neophytadiene than enriched and intermediate aroma style tobacco. Intermediate aroma tobacco contained extremely significant lower proportion of Phenylalanine products and Cemdrenoid products than enriched and clear aroma tobacco.

Keywords: ?ue-cured tobacco; aroma type; aroma components; proportion; difference

烟叶香型风格的差异是由其化学成分的含量和组成决定的[1]。香味物质总量与烤烟香味品质的相关性并不显著,国外有研究认为烤烟香气风格的主要差异是致香成分间组成比例不同而造成[2]。目前,国内对烤烟致香物质的研究主要集中在不同品种、部位、基因型、生态区域、栽培措施、烘烤调制技术等条件下致香物质种类和含量的差异上,但对烟叶致香成分组成比例上差异的研究的报道较少[3-7]。致香物质在总量中的组成比例(以下简称总占比)能在相对统一标
