| 摘 要： | 采用三段式烘烤工艺,研究特色烤烟品种红花大金元不同部位叶片烘烤过程中蛋白酶、淀粉酶、多酚氧化酶活性变化规律。结果表明:蛋白酶和淀粉酶活性在烘烤过程中呈上升→下降→再上升→再下降的趋势;多酚氧化酶活性则随着烘烤时间的推移总体呈下降趋势。从蛋白酶和淀粉酶活性变化规律看,通过适当延长烘烤变黄时间、调控变黄相对湿度,有望达到适当降低烤后烟叶淀粉含量及上部叶蛋白质含量的目的。

| Abstract: | Using ＇ three stage＇ flue - curing mothed, the experiment studied the changing regularity of several enzyme＇ s activity of Honghuadajinyuan during flue - curing. The result showed that the protease and amylase＇s activity appeared the curve of double peak within the proceeding of flue- curing, meanwhile, the activity of polyphenol oxidase tended to decrease, which indicated that extend the time and control the relative humidity of yellowing - stage propriety could reduce the starch＇ s content and protein content of upper leaves. |
