In order to master the law of odor components changes in tobacco flue-curing during curing
electronic nose composed of metal-oxide semiconductor(MOS)sensors array is used to monitor the odor during tobacco flue-curing process.A self-made electronic nose system and experiment are described in detail
after datas pre-processing
principal component analysis(PCA)method is used for analysis on sample.Analysis result indicates that the odor synthetized curve derived from the electronic nose technology can reflects overall trend of odor during tobacco flue-curing process truly and effectively
and the law of odor changes obtained from anlaysis is in accordance with tobacco flue-curing theory at present well.
