摘要:
考察了云南部分烟叶产地、部位和品种对主流烟气中主要酚类化合物含量的影响及与感官质量之间的相关关系,结果表明:主流烟气中的主要酚类化合物包括对苯二酚、间苯二酚、邻苯二酚、苯酚、间甲酚、对甲酚和邻甲酚,这7种酚类化合物的含量受烟叶的产地、部位和品种的影响较大,变异系数均大于15%,最高达到80%,其中着生部位的影响最大,最大变异系数达到63.5%;在主流烟气中这7种酚类化合物的含量间呈现复杂的关系,均表现为极显著的正相关.通过因子分析发现,主流烟气中这7种酚类化合物的含量与感官质量部分指标间也有较为明显的相关性,随着综合得分的增加,劲头和烟气浓度的感官得分均增加,而刺激性和湿润程度得分显著减少,香型偏向浓香型,对香气、杂气和余味影响较小.
Abstract:
The effect of origin,part and variety at major phenolic compounds of mainstream smoke,and the relativity of contents of major phenolic compounds in mainstream smoke with the smoking quality were investigated.The results showed that the origin,position and variety were huge to contents of these compounds,including diphenol,resorcinol,catechol,phenol,m-cresol,p-cresol,and o-cresol,CV15%,the maximum approximately remained at 80%,in which,the position was the key determinant,the biggest CV was 63.5%;the contents of these seven compounds had a complicated relativities,which had the significant positive correlation with one another.The results of bivariate and factor analysis showed that the smoking quality were influenced by these seven compounds.With the increase of comprehensive factor score,the scores of physiological and taste strength would increase,while moist degree and irritancy would reduce,and the flavor of aroma would tend to heavy,but hardly change the aftertaste,offensive odor and aroma.
