摘要(Abstract):

为找出醇化片烟制丝耐加工性较强的醇化周期,探究烟叶物理特性指标与烟丝结构之间的相关关系,以烟叶穿透强度作为片烟制丝耐加工性评价方法的关键物理特性指标,通过优化醇化片烟穿透强度检测方法的参数,建立了制丝耐加工性评价方法,并分析了醇化过程中不同等级片烟穿透强度的变化规律及变化程度。结果表明:(1)片烟样品的穿透强度与整丝率、长丝率均存在极显著正相关关系,与短丝率存在极显著负相关关系(P<0.01),可作为评价醇化片烟制丝耐加工性的关键物理特性指标。(2)明确了醇化片烟穿透强度测定方法的参数:在保证双侧90%置信区间的前提下,所需最少样本量为64,样品尺寸以(2~3)cm×(2~3)cm为宜。(3)在片烟醇化18-27月期间,3个产地不同等级片烟样品穿透强度降幅平均值由大到小依次为B2F等级、C2F等级、C4F等级,B2F和C2F等级样品穿透强度在醇化27月时下降幅度达到差异显著水平(P<0.05),C4F等级样品穿透强度在醇化24月时下降幅度达到差异显著水平(P<0.05)。(4)以提高制丝的经济性和控制物理质量为目的,对C4F等穿透强度较低的片烟应在醇化24月之内进行制丝加工,对B2F等穿透强度较高的片烟应在醇化27月之内进行制丝加工。
