白肋烟是典型的晾烟 ,调制过程在特定的晾房中进行 ,历时 5 6d ,在此过程中 ,淀粉酶、淀粉、可溶性总糖、还原糖都随晾制进程而下降、随叶位升高而增添 ,且彼此的动态相关联 .淀粉酶活性降幅较快的时间在晾制的3～ 6d ,比淀粉含量下降较快的时间稍有滞后 ,它的消长规律还与叶片含水率变化正相关 .晾制结束时 ,上、中、下各叶位淀粉、可溶性总糖、还原糖含量均在优质白肋烟适宜化学成分指标范围内 ,证实当地现行生产技术规范切实可行 .
Burley is a typical air-cured tobacco, the modulation process carried out in a specific air room, which lasted 56 days, in the process, amylase, starch, soluble total sugar, reducing sugar with the air-drying process decreased, with the leaf position Increased and increased, and the dynamics of each other.Amylase activity decreased rapidly in the air-dried 3 ~ 6d, slightly lower than the starch content decreased slightly lag time, and its growth and decline of the law also with changes in leaf water content Positive correlation.At the end of the air-curing, starch, soluble total sugar and reducing sugar content at the upper, middle and lower leaves were all within the range of suitable chemical composition indexes of high-quality burley tobacco, which confirmed that the local production technical specifications were feasible.
