复烤片烟自然醇化过程中主要化学成分含量与感官质量的关系

摘要

为筛选能表征复烤片烟自然醇化品质的化学指标，以云南省4个产区复烤片烟为试验材料，研究了自然醇化条件下复烤片烟主要化学成分含量与感官质量的关系。结果表明：pH值的变异系数最小，变幅为5．10～5．37，平均值为5．22；pH值、两糖差、总氮含量、烟碱含量、氮碱比、糖碱比、蛋白质含量和淀粉含量等指标与感官质量评价指标呈极显著或显著线性相关关系；总糖、总氮、烟碱含量以及糖碱比、pH值与感官质量评价指标呈极显著典型相关关系；pH值、两糖差、总氮含量与感官质量呈极显著的三次曲线关系，烟碱含量、糖碱比、蛋白质含量与感官质量呈极显著或显著的二次方关系。综合分析结果认为，pH值、两糖差、烟碱含量、糖碱比可以作为复烤片烟自然醇化过程中的品质评价指标。%In order to select the chemical indexes which can characterize the quality of redried lamina of flue-cured tobacco, the relationship of the main chemical components content and smoking quality of redried lamina of flue-cured tobacco from four producing areas in Yunnan province during natural aging was analyzed.The results indicated that pH value had the minimum variation,ranging from 5.10 to 5.37, with an average of 5.22.The pH value,the difference between total sugar and reducing sugar,total nitro-gen content,nicotine content,nitrogen-nicotine ratio,sugar-nicotine ratio,protein content and starch con-tent were extremely significantly or significantly correlated with smoking quality.Total sugar content,total nitrogen content,nicotine content,sugar-nicotine ratio and pH value had an extremely significant canoni-cal correlation with smoking quality.pH value,the difference between total sugar and reducing sugar,and total nitrogen content showed an extremely significant cubic curve relationship with smoking quality.Nico-tine content,sugar-nicotine ratio and protein content assumed extremely significant or significant quadratic connection with smoking quality.According to the results,pH value,the difference between total sugar and reducing sugar,nicotine content and sugar-nicotine ratio can be used as the main indexes to evaluate the quality of redried lamina of flue-cured tobacco during natural aging.
