Title: Analysis of Relationships between Neutral Aroma Constituents and Aroma Concentration and Quality in Flavor Enriched Flue-cured Tobacco in Central Henan Province
Abstract: To determine material basis for the impact of aroma concentration and quality of flue-cured tobacco,using partial correlation analysis,path analysis,and stepwise regression analysis,the authors carried out quantitative relations analysis between neutral aroma constituents and concentration and quality of aroma in flue-cured tobacco.The results showed that regression model of quality of aroma and concentration of aroma of great significance were established,and both of these were significant at 1% level.16 kinds of representative neutral aroma constituents in flue-cured tobacco had different direct influence on quality and concentration of aroma.Megastigmatrienone-3 had the greatest direct positive influence on concentration of aroma,megastigmatrienone-2 had the greatest direct negative influence on quality of aroma.Megastigmatrienone-2 had the greatest direct positive influence on concentration of aroma,β-damascenone had the greatest direct positive negative influence on concentration of aroma.Megastigmatrienone-1,phenylethanol,furfural and neophytadiene had direct influence on quality of aroma.Pseuaoinonone,benzaldehyde,2-acetyl pyrrole and solanone had direct negative influence on concentration of aroma.
