摘　　要：为考察打叶复烤过程中关键工艺参数变化对云产烟叶模块质量的影响,选取“清甜香”风格特征适中的文山模块烟叶为研究对象,根据Box-Behnken Design(BBD)设计原理,以润叶含水率、润叶温度和复烤温度为主要影响因素,复烤叶片含水率和CCUI值为响应值,采用响应曲面法优化打叶复烤工艺条件,并建立相应的预测数学模型。结果表明:复烤叶片含水率、CCUI值与各关键工艺参数之间的变化均符合二次方程模型(R2分别为0.9451和0.8557),复烤温度对叶片含水率和CCUI值影响均较大,优化后最佳工艺参数为润叶含水率17.5%、润叶温度58.0℃、复烤温度406.0℃;优化条件下复烤叶片含水率9.627%、CCUI值0.851,其CCUI值较正常生产提高3.780%,内在品质提升显著(P<0.01),大片率和叶含梗率降低明显,干草香、正甜香和青香等香韵风格特征和感官品质更加凸显,说明适当提高润叶温度和复烤温度更有利于降低复烤叶片大片率、提升中小片率,彰显云产“清甜香”特征适中的烟叶模块风格和感官品质。To investigate the influences of key parameters of threshing and redrying on the quality of tobacco leaf modular from Yunnan,Wenshan leaf modular with a moderate“fresh-sweetness scent”style leaf were studied.On the basis of Box-Behnken Design(BBD)principle,the conditions of threshing and redrying were optimized by adopting the response surface methodology and taking the moisture content in conditioning,conditioning temperature and redrying temperature as major influencing factors and the moisture content and CCUI values of redried strips as response values,and the corresponding prediction mathematical models were established.The results showed that the relationships between the moisture content and CCUI values of redried strips and key technological parameters were all consistent with the quadratic equation model(the values of R2 were 0.9451 and 0.8557 respectively).Redrying temperature affected both the moisture content and CCUI values of the strips greatly.The optimal parameters were moisture content during conditioning at 17.5%,conditioning temperature at 58.0℃,and redrying temperature at 406.0℃.Under the optimized condition,the moisture content in the redried strips was 9.627%and its CCUI value was 0.851,which increased by 3.780%compared with that of regular production.The intrinsic quality of redried strips was significantly improved(P<0.01).The percentage of large-sized strips and the stem contents in the strips decreased significantly.The aroma notes of hay-like,pure-sweetness and green scents and sensory quality of the redried strips were more prominent.It indicated that properly raising conditioning temperature and redrying temperature were more beneficial in reducing the percentage of large-sized strips,increasing the percentage of medium and small-sized strips,and enhancing the style characteristics and the sensory quality of tobacco leaf modular from Yunnan.
