摘要: 以云烟87初烤烟叶Y2B4配方叶组为供试材料,在一润和复烤工艺下分别设置3种加工强度,分析不同加工强度下烟叶化学成分的变化。结果表明,烟叶常规化学成分主要包括总糖、还原糖、总植物碱、氯、钾、总氮、淀粉、蛋白质、果胶;致香物质包含醇类、醛类、酮类、酯类、酚类、烯烃类、杂环类。一润和复烤工艺下,降低加工强度处理的可用性指数(CCUI)均高于常规加工强度处理,表明降低加工强度处理的烟叶常规化学成分协调性更优,工业可用性更好。不同加工强度的一润、复烤烟叶样品聚类效果较好,均表现为常规加工强度处理、升高加工强度处理样品聚为一类,降低加工强度处理样品聚为一类,表明加工强度对烟叶致香物质组成具有显著影响。β-大马酮、巨豆三烯酮 D、西柏三烯二醇 C、亚麻酸甲酯、淀粉的含量均与烟叶感官质量总分呈正相关关系,总植物碱含量与烟叶感官质量总分呈负相关关系。降低加工强度处理的复烤烟叶香韵、香气质、干净度、湿润感、回味得分均高于常规加工强度处理和升高加工强度处理,杂气较少,感官质量总分最高。

Abstract: Using the Y2B4 formula lamina group of the flue-cured tobacco variety Yunyan 87 as test material, three processing intensities were set during the primary conditioning and redrying processes to analyze the changes in chemical components of tobacco leaves under different processing intensities.The results showed that the routine chemical components of tobacco leaves included total sugar, reducing sugar, total alkaloids, chlorine, potassium, total nitrogen, starch, protein, and pectin.The aroma components mainly included alcohols, aldehydes, ketones, esters, phenols, olefins, and heterocyclic compounds.Under both the primary conditioning and redrying processes, the CCUI of the reduced processing intensity treatment was higher than that of the conventional processing intensity treatment, indicating that the tobacco leaves treated with reduced processing intensity had better coordination of routine chemical components and higher industrial usability.The cluster analysis of tobacco leaves samples from primary conditioning and redrying under different processing intensities showed good clustering effects.Samples from the conventional processing intensity and increased processing intensity treatments clustered into one group, while samples from the reduced processing intensity treatment clustered into another group. This indicated that processing intensity had a significant effect on the composition of heteroaroma components in tobacco leaves. The contents of β-damascone, megastigmatrienone D, cembratriene-diol C, methyl linolenate, and starch all showed positive correlations with the total sensory quality score of tobacco leaves. Total alkaloid content also showed a negative correlation with the total sensory quality score of tobacco leaves. The redried tobacco leaves treated with reduced processing intensity had higher scores in aroma profile, aroma quality, cleanliness, moistness, and aftertaste compared to those treated with conventional processing intensity and increased processing intensity. They exhibited less off-odor and achieved the highest total sensory quality score.
