Effect of Different Baking Process on the Volatile Aroma Substances of the Flue-cured Tobacco Leaves
[Objective] To explore the best curing process for improvement of the K326' s upper leaf aroma quality and realize the improvement of its quality and flavor during curing period.[Method] The effects of different baking processes on the content of volatile aroma substances in upper leaves of K326 were studied using the airflow decrease bulk curing barn at Chongqing tobacco growing areas.[Result] The results showed that:in the study of 47 kinds of tobacco volatile aroma precursors,in addition to a few substances,the content of volatile precursor substances in moderate temperature and humidity processing,the highest amount of moderate temperature and humidity processing that moisture by outside power,is 352.03 μg/g,the minimum low temperature and low humidity treatment,is 310.61 μg/g.[Conclusion] Therefore,the moderate temperature and humidity processing will improve the content of aroma precursors in K326' s upper leaf,also help to improve the quality of it' s smoke aroma.
