摘　　要：将电子鼻气味指纹数据应用于对加香前后烟丝的检测,旨在寻求一种快速有效的方法以实现对加香烟丝的质量监控。通过主成分分析法处理电子鼻对加香前后烟丝挥发性成分的指纹数据,发现该分析方法能够有效区分加香前后的烟丝,而且还能够有效评价烟丝加香的均匀性。采用统计质量控制分析法处理加香后烟丝挥发性成分指纹数据,发现该分析方法能够有效的对加香后烟丝的气味品质进行生产过程中的质量监控。利用电子鼻货架寿命分析了贮存时间对加香烟丝挥发性成分的影响趋势,发现加香烟丝的挥发性成分随着贮存时间的延长逐渐减少,综合考虑随着贮存时间的延长,加香烟丝挥发性成分的均匀性越好和加香烟丝挥发性成分损失越多两个方面的因素,得出加香烟丝在贮丝柜的最佳贮存时间范围。In order to obtain a fast and available process to control the quality of flavored cut tobacco, the sensor array fingerprint technology of electronic nose （E-nose） was applied in identifying of flavored cut tobacco according to volatile compounds. The data acquired by electronic nose were analyzed by the principal component analysis （PCA） in order to reduce data dimension and optimize feature vectors. The results indicated that electronic nose could discriminate cut tobacco from flavored cut tobacco and evaluate the uniformity of flavored cut tobacco effectively. The data analyzed by Statistical Quality Control （SQC） could evaluate the quality of flavored cut tobacco effectively according to the volatile components in cut tobacco during the production process. The shelf life of the electronic nose analyzed the effect of the storage time on change of volatile components of flavored cut tobacco. The results indicated that the volatile components of flavored cut tobacco decreased with the increase of the storage time; however, the uniformity of flavored cut tobacco was better with the increase of the storage time. According to the two factors, the best storage time for flavored cut tobacco was identified.
