摘要: 采用基本描述统计、单因素方差分析和主成分分析方法,分析了国产烤烟与津巴布韦、巴西烤烟挥发性香味物质的差异性.结果表明:1)国内烤烟各类香味物质含量低于津巴布韦和巴西的烤烟,香味物质的总量以津巴布韦烤烟最高,其次是巴西烤烟,国产烤烟略低一些;2)国内烤烟与巴西、津巴布韦烤烟之间的各类香味成分含量除了新植二烯和呋喃类外都有显著差异;3)烤烟综合质量得分为津巴布韦烤烟 >巴西烤烟> 国内烤烟.Abstract: The difference of volatile aromatic compounds (VAC) in flue-cured tobacco from China,Zimbabwe and Brazil was analyzed using the basic descriptive statistics single factor,ANOVA and principal component analysis.The results showed that:1) for all kinds of flavor material in flue-cured tobacco,domestic tobacco was less than Zimbabwe's and Brazil's,while Zimbabwe's had the highest total amount of VAC,followed by Brazil,and the domestic tobacco was lower than both;2)domestic tobacco and Brazil,Zimbabwe tobacco had significantly differences in all kinds of flavor ingredients besides neophytadiene and furans;3) tobacco integrated quality ranked as Zimbabwe> Brazil> Domestic.
