Physical and physiological biochemical characteristics of cured tobacco leaves had changed greatly during the tobacco curing stage, especially during the yellowing stage of tobacco curing.
在烤烟烘烤过程中,尤其是烘烤的变黄阶段,烟叶体内进行着激烈的物理和生理生化变化,其中物理变化是指烟叶内的水分不断地汽化排出叶片组织,使烟叶逐渐干燥;生理生化变化则包括新鲜烟叶组织细胞在呼吸酶类、水解酶类及氧化还原酶类等的作用下,使烟叶内含物分解、转化、消耗和小分子有机物质不断形成的全过程。
补充资料：变温吸附
利用吸附剂的平衡吸附量随温度升高而降低的特性，采用常温吸附、升温脱附的操作方法。除吸附和脱附外，整个变温吸附操作中还包括对脱附后的吸附剂进行干燥、冷却等辅助环节。变温吸附用于常压气体及空气的减湿，空气中溶剂蒸气的回收等。如果吸附质是水，可用热气体加热吸附剂进行脱附；如果吸附质是有机溶剂，吸附量高时可用水蒸气加热脱附后冷凝回收；吸附量低时则用热空气脱附后烧去，或经二次吸附后回收。
