摘　　要：为探索滚筒烘丝过程干头干尾烟丝与正常烟丝品质差异的判定方法，考察了干头干尾烟丝整丝率、整丝率变化率、堆密度及表观密度等物理指标的变化趋势，并基于上述物理指标对不同含水率的烟丝样品进行系统聚类分析，最后通过感官质量评吸对聚类分析结果进行验证。结果表明：①干头干尾烟丝的整丝率、整丝率变化率、堆密度及表观密度均与含水率存在明显的相关性。②以含水率8.72%～9.46%为聚类分界点，不同含水率的烟丝样品可分为两类。③含水率≤8.72%的干头干尾烟丝与正常水分烟丝的整体感官质量存在显著差异。综合物理指标分析及感官质量验证结果，干头干尾烟丝与正常烟丝品质差异的含水率临界点应在9.00%左右。Physical indexes such as whole cut rate, its changing ratio, bulk density and apparent density were investigated to determine industrial availability of over-dried cut tobaccos with different moisture contents. Cluster analysis was used to analyze data and sensory evaluation was also carried out to verify outcomes. Results showed that： ①Whole cut rate, its changing ratio, bulk density, apparent density were highly correlated with moisture content. ② Cut tobacco samples with different moisture contents could be clustered into two categories with cut-off point of 8.72%-9.46%moisture content.③Overall sensory quality of over-dried cut tobacco with moisture content lower than 8.72%was significantly different from normal cut tobacco. The quality-concerned critical moisture content for over-dried cut tobacco was about 9.00%.
