Characterizing flavoring uniformity in tobacco based on hyperspectral detection
To address the issues of complexity,low accuracy,high personnel requirements,and inability to adapt to the demand for large-scale real-time monitoring in the current detection methods for flavoring content and uni-formity in tobacco,a characterization method for the uniformity of flavoring in tobacco based on hyperspectral detec-tion had been developed.The method utilized a self-developed hyperspectral system to capture fluorescence hyper-spectral images of tobacco before and after flavoring,and performed weighted unmixing on the fluorescence hyper-spectral images.Based on the unmixing coefficients,a characterization index R for the content of flavoring applied to tobacco leaves was established,and the coefficient of variation(CV)of R was used to represent the uniformity of flavoring in the tobacco.Verification conducted on flavored tobacco leaves from actual production lines,it was found that the magnitude of R was positively correlated with the content of flavoring in the tobacco,and the CV could accurately determine the uniformity of flavoring in the tobacco.This method could be used for the detection and monitoring of flavoring quality of an known fragrance samples in the actual production process of tobacco.
