Abstract:
In order to explore the aroma components and fragrance characteristics of the new tobacco variety Zhongchuan208(ZC208), aroma compounds in the cured leaves of ZC208 and Zhongyan100(ZY100) were determined and compared using the HS-SPME-GC/MS method.Differences between the two varieties were assessed through cluster analysis.Additionally, fragrance characteristics and sensory quality were evaluated.The results revealed the presence of a total of 80 aroma compounds in both varieties.Among these, ZC208 exhibited significantly or extremely significantly higher levels than ZY100 in 28 aroma compounds across five ecological regions in Shandong Province.The aroma components were influenced by both genotype and ecological environment.ZC208 was notably affected by ecological environment, suggesting a stronger reflection of regional characteristics.Moreover, ZC208 demonstrated higher sensory quality than ZY100.In the five ecological regions, the average content of aroma components in ZC208 was 57.68 ng/g, surpassing that of ZY100(39.72 ng/g).The improvement in sensory quality in ZC208 and its fragrance characteristics may be attributed to the significant or extremely significant increase in the content of aroma components.
