Title: Research on relationships between neutral aroma constituents and smoking results of flue-cured tobacco in Panxi tobacco-growing areas
Abstract: To research on quantitative relations between neutral aroma constituents and smoking results of flue-cured tobacco in Panxi tobacco-growing areas,the authors carried out partial correlation analysis,path analysis and stepwise regression analysis.The results showed that regression model of quality of aroma,concentration of aroma and smoking total scores were established,and all of their correlation were significant at 1 level.25 kinds of representative neutral aroma constituents in flue-cured tobacco had different direct influence on quality of aroma,concentration of aroma and smoking total scores.6-me-5-heptene-2-dione from the degrading products of carotene had greatest direct positive influence on concentration of aroma.Benzvl alcohol from the degrading products of hypoglycemia compounds had greatest direct negative influence on concentration of aroma.2-acetyl furan from browning reaction had greatest direct positive influence on quality of aroma.Neophytadiene had greatest direct negative influence on quality of aroma.2-acetyl furan from browning reaction had greatest direct positive influence on smoking total scores.6-me-5-heptene-2-dione from the degrading products of carotene had greatest direct negative influence on smoking total scores.Both neryl acetone and benzofuranone from the degrading products of carotene had direct positive influence on quality of aroma,concentration of aroma and smoking total scores.2,4-hendiene-al and 6-me-2-dione from the degrading products of carotene had direct negative influence on quality of aroma,concentration of aroma and smoking total scores.It proves that aroma components that are good for smoking could be improved by regulating the modulation conditions.The aroma components that are bad for smoking should be reduced possibly.
