云南烤烟化学成分与香气品质的关系研究

Study on Relationship between the Chemical Components and Aroma Quality of Yunnan Flue-cured Tobacco

化学成分与香气品质的相关分析表明,与香气品质关系密切的化学成分主要为糖组分、含氮化合物和总灰分。化学成分与香气质、香气量的逐步回归分析表明,化学成分对香气质作用的大小为:挥发碱>总糖>总氮>总灰分,对香气量作用的大小为:总灰分>总糖。

The correlation analysis between the chemical components and aroma quality showed that the chemical components which had close relation with aroma quality were mainly sugar,the chemical compound including nitrogen and total ash. The step regression analysis showed that the effects of chemical components on the aroma character were alkali > total sugar > total nitrogen > total ash, the effects of chemical components on the aroma quantity were total sugar total ash > total sugar.
