Abstract
The effect of different temperature of the yellowing stage on changes of contents of main carbohydrate of flue-cured tobacco leaf during the flue-curing process was studied,the result showed that the degeneration of most content of starch and the accumulation of total sugar and reducing sugar happened during the whole yellowing stage and early color fixing stage.The contents of starch and total sugar of tobacco leaf have no difference during treatments until curing process ended,but the content of reducing sugar and the ratio of reducing sugar and total sugar increase as temperature of yellowing stage decrease.The study shows that the content of reducing sugar and the ratio of reducing sugar and total sugar are high when temperature of the yellowing stage is between 31~35℃.
