2、拉大干湿球温差,延长38℃变黄阶段烘烤时间,烤后烟叶质量较好,桔黄烟叶比例较高,杂色烟比例较少;42℃变黄凋萎阶段烘烤时间控制在10~20h、湿球控制36℃的处理较好,烤后成熟度较好,桔黄烟叶比例较大,杂色烟叶较少,湿球温度低,虽有利减少杂色烟叶,但青筋烟较多,湿球温度高的处理杂色烟叶比例加大,颜色深暗;变黄时间中下部烟叶以60h较为适宜,上部烟叶以65h较为适宜,烤后成熟度较好,桔黄烟叶比例较大,杂色烟叶比例较少;评吸质量表现为随着38、42℃变黄阶段的湿球温度增高和42℃凋萎时间拉长,烟叶评吸
3、质量逐渐变差;烟叶主要化学成分表现为随着38、42℃变黄阶段的湿球温度增高和42℃凋萎时间拉长,烟叶总糖、还原糖明显减少,烟碱增加,其他化学成变化不大。关键词:烟叶烘烤;密集烤房;变黄时间;温度;湿度中图分类号:S572文献标识码:A文章编号:1001-8581(2012)07-0085-05EffectsofDifferentBakingTime,TemperatureandHumidityatYellowingStageonQualityofTobaccoLeaf112233XUWei,XIA
