四川白肋烟不同品种中性香气成分含量及感官品质分析

Quantitative determination of neutral volatil aroma component and sensory evaluation of air-cured leaves of major Chinese burley varieties

采用气质联用仪对四川白肋烟不同品种晾制后上部叶和中部叶的中性香气物质含量进行定量分析,并卷制单料烟进行感官评吸。结果表明,总中性香气物质含量高低排序为达白1号>鄂烟1号>TN90>达所24>宣汉-5;达白1号巨豆三烯酮、大马酮等类胡萝卜素降解产物和腺毛分泌物降解产物茄酮含量丰富,TN90和鄂烟1号大部分香气成分与达白1号接近;宣汉-5的类胡萝卜素降解产物含量以及上部叶的茄酮含量显著低于其他品种,但大部分苯丙氨酸裂解产物和中部叶糖的裂解产物含量较高。评吸结果表明,达白1号的风格程度、香气质和香气量得分均为最高,香气品质较好,其次为TN90、鄂烟1号;宣汉-5的白肋烟风格程度较低,香气量少,香味品质较差。

GC/MS was used to analyze neutral aroma components content inr upper and middle stalk position air-cured leaves of major hurley varieties, and experimental cigarettes were made to conduct sensory evaluation. Results showed that total content of neutral volatile aroma components followed the order of Dabai 1 〉 Eyan 1 〉 TN90 〉 Dasuo 24 〉 Xuanhan-5. Dabai 1 was abundant in carotenoid catabolites, such as megastigmatrieonel and β-damascone et al, and in cembratriendiol catabolite （solanone）. The content of most aroma components for Eyan 1 and TN90 were at the similar level as Dabai 1. The content of carotenoid catabolites and solanone for Xuanhan-5 were significantly lower than that of other varieties, while the content of most phenylalanine catabolites in both stalk positions and sugar catabolites in middle stalk position were significantly higher. Sensory evaluation results showed that Dabai 1 had the highest scores for budey style, aroma quantity and quality, indicating good aroma quality, followed by TN90 and Eyan 1. Xuanhan-5 had the lowest scores for burley style and aroma.
