Abstract: In order to provide theoretical guidance for improving the usability of tobacco leaves in Argentina,the quality difference between Argentina tobacco leaves and K326 tobacco leaves in Yunnan was studied.The chemical composition,appearance quality,sensory evaluation quality and aroma components of Argentina tobacco leaves and K326 tobacco leaves in Yunnan were comprehensively analyzed and compared.Compared with K326 tobacco leaves in Tengchong and Shidian of Yunnan,the content of total alkaloid,water soluble total sugar and reducing sugar of Argentina Salta tobacco were generally low,the potassium and chlorine content was quite,the tobacco leaf tissue structure was loose,the content of oil was better,the content of total aroma components was significantly higher,and the sensory evaluation of aroma quality and quantity was better.The overall quality of Argentina tobacco is slightly better than that of K326 tobacco leaves in Yunnan,which could be applied to Chinese flue-cured tobacco formula.However,it is necessary to solve the defects of local tobacco flavor in use.
