Study on Technologies for Improving Quality and Usability of Burley Tobacco

In order to solve the problems of excessive nicotine and deficient in characteristic flavor of burley tobacco and improve quality and usability, varieties selection and breeding, cultural practices, curing conditions, aging technology and relationship between quality and flavor components of domestic burley tobacco were systematically studied. The varieties and relative key technological measures contributed to producing high quality burley tobacco with appropriate nicotine content were determined. The flavor components in both foreign and domestic burley tobaccos from different stalk positions were compared. The variation of 20 kinds of important flavor components in burley tobacco during growing, harvesting and curing was revealed. The rule of quality change during aging and the optimal aging conditions were also found.
