Abstract

This experiment was carried out to investigate the effect of circulating air volume to chemical composition of tobacco leaves during the bulk curing. The results were as follows : The decrease of circulating air volume prolonged curing time as the case of a 0.058m3/min. kg; but, no remarkable changes with a 0.11m3/min. kg and a 0.083m3/min. kg. When the circulating air volume was decreased, compared with 0.11m3/min. kg, sugar content was increased while total nitrogen and nicotine content showed a reduced values. In case of a 0.058m3/min. kg and a 0.083m3/min.kg, solanone and damascenone were high. Some of volatile neutral constituents and volatile organic acids were increased during curing process ; especially, their quantities were remarkably increased during the midrib drying stage. As circulating air volume decreased the equilibrium moisture content was increased, while leaf shatter index and filling capacity were decreased.
