摘　　要：为探索箱式贮叶过程中片烟内在品质的变化,选取云南某卷烟烟叶配方模块为试验对象,分别在木质箱中进行了4,14,24,48和96 h不同贮叶时间试验,通过采集不同贮叶时间样品的近红外光谱并利用主成分分析-马氏距离(PCA-MD,Principal component analysis-Mahalanobis distance)分类法建立相应的表征类模型,并进行了感官评价验证。结果表明,随着贮叶时间的增加,烟叶品质的变化幅度逐渐减小;贮叶48 h烟叶品质改善明显,且品质趋于稳定。In order to find out the variation trend of intrinsic quality of strips stored in cases, blended strips of a cigarette brand from Yunnan were stored in wooden cases for 4, 14, 24, 48 and 96 hours, respectively. By collecting the near-infrared spectra of strips samples stored for different durations, the corresponding characterization class models were developed with principal component analysis-Mahalanobis distance （PCA-MD） classification method, and validated by sensory evaluation. The results showed that the variation of tobacco quality decreased with the length of storage duration. The quality of tobacco improved significantly and tended to stabilize after storing for 48 hours.
