    摘要:

    为了明确初烤烟叶的主要理化指标与感官评吸质量的相关性,对感官评吸质量进行预测。在文山收集和检测了222份中部烟叶样品,并进行了典型相关和多元回归分析。结果表明:圆润感、余味、香气量、透发性与烟叶外观质量中的颜色、油分、身份有极强的相关性,选取的前两对有效典型变量的累积贡献率达98.13%;其次圆润感、刺激性、余味、透发性、杂气、香气量、干燥感与烟叶含梗率、叶宽、平衡含水率之间具有一定相关性,选取的前两对有效典型变量的累积贡献率达99.04%。香气量、透发性与烟叶常规化学成分中钾、糖碱比、烟碱之间也同样存在相关关系,选取的前两对有效典型变量的累积贡献率达93.29%;逐步回归分析建立的方程进一步表明,评吸总分与成熟度、平衡含水率、含梗率、总植物碱、还原糖、糖碱比、氮碱比、两糖比、钾氯比呈现正相关水平。综上所述,依据典型相关分析和回归分析得出的理化指标与感官评吸质量之间的回归方程可对感官评吸质量进行综合预测。

    Abstract:

    In order to identify the relationship between the major physical and chemical indexes with the smoking quality of the primary cured tobacco leaves,the sensory quality was predict.A total of 222 tobacco samples were collected and tested in Wenshan,and the typical correlation and multiple regression analysis were carried out.The results showed that the combination of mellowness,aftertaste,flavor quality and volatility had a strong correlation with leaf color,oil and identity,and the cumulative contribution rate of the first two pairs of canonical variables reached 98.13%.The comprehensive indexes of mellowness,irritation,aftertaste,volatility,offensive taste,flavor quality and dryness are correlated with stem content,leaf width and equilibrium moisture content.The cumulative contribution rate of the first two to the typical variables is 99.04%.The combination of flavor quality and volatility was also correlated with potassium,ratio of reducing sugar to total sugar and nicotine in chemical composition.The cumulative contribution rate of the two pairs of effective typical variables was 93.29%.The equation established by stepwise regression analysis showed that the descriptive of smoking quality showed positive correlation with maturity,equilibrium moisture content,stem content,total plant alkali,reducing sugar,ratio of reducing sugar to nicotine,ratio of total nitrogen to nicotine,ratio of reducing sugar to total sugar,and K/Cl ratio.In conclusion,according to the regression equation between physical and chemical indexes and sensory assessment quality obtained by canonical correlation analysis and regression analysis,sensory assessment quality can be comprehensively predicted.
