Analysis on the Contents of Total Volatile Acids and Volatile Bases of Flue-cured Tobacco in Hongda Variety

[Objective] To determine and analyze total volatile acids and volatile bases of flue-cured tobacco Hongda variety.[Method] Total volatile acids and total volatile bases contents in C3F leaves of Hongda variety from Dali,Yunnan were quantitatively determined with continuous flow method.[Result] The results showed that the contents of total volatile acids averaged 955.84 μg/g,and total volatile bases contents averaged 1 098.23 μg/g.The contents of total volatile acids in Hongda variety were significantly higher than that in other varieties,while the contents of total volatile bases in Hongda variety were significantly lower than that in other varieties.The contents of total volatile acids in Hongda variety from dry land was significantly higher than that from paddy land;the contents of total volatile bases in Hongda variety from dry land was indistinctively lower than that from paddy land.The contents of total volatile acids in Hongda variety from high altitude were significantly higher than that from medium and low altitude;the contents of total volatile bases in Hongda variety from low altitude were significantly higher than that from medium and high altitude.The contents of total volatile bases in Hongda variety from Honghe river basin and Binghu river basin were significantly higher than that from Lancangjiang river basin and Jinshajiang river basin.[Conclusion] The study can provide basis for theoretical research and production of improving flue-cured tobacco aroma quality and quantity,and provide reference for proper utilization of Hongda variety tobacco.
