四川烤烟烟叶细胞壁物质含量与外观质量、感官质量的关系

Relationship Between Cell Wall Matter Content in Sichuan Flue-cured Tobacco and its Appearance and Sensory Quality

为了探讨烤烟细胞壁物质含量与烟叶质量的关系,对四川烤烟烟叶细胞壁物质含量进行了测定,并分析了其与外观质量、感官质量的关系。结果表明,四川烤烟烟叶中总细胞壁物质、全纤维素、木质素、果胶、半纤维素、纤维素含量范围分别为24%～35%,10%～16%,0.5%～4%,5%～9%,2%～5%,5%～9%。总细胞壁物质含量、全纤维素含量、半纤维素含量、纤维素含量与身份(外观质量)呈显著相关关系,与其他外观质量指标相关性不显著。总细胞壁物质含量与香气质(感官质量)得分显著负相关,与其他感官质量指标相关性不显著。

In order to investigate the relationship between cell wall matter content in flue-cured tobacco and tobacco leaf quality,the cell wall matter content in Sichuan flue-cured tobacco was determined and its relationship with appearance and sensory quality was analyzed.The results showed that in Sichuan flue-cured tobacco,the contents of total cell wall matter,total cellulose,lignin,pectin,hemicellulose,and cellulose ranged from 24% to 35%,10% to 16%,0.5% to 4%,5% to 9%,2% to 5%,5% to 9%,respectively.The contents of total cell wall matter,total cellulose,hemicellulose and cellulose significantly correlated with leaf body,while their correlations with other appearance qualities were not significant.The content of total cell wall matter significantly correlated with aroma quality of leaf;while its correlations with other sensory qualities were not prominent.
