Rapid Determination of Solanone in Flavor Component of Tobacco by NIR Diffuse Reflectance Spectroscopy

A method to simultaneously analyze flavor components (analytes) in tobacco by FT-NIR was developed based on the spectra of 500 samples for the calibration samples.For all samples,the raw spectra were pretreated as second derivative and Norris derivative filter(7,5).partial least square (PLS) was used as the calibration algorithm.About 20 randomly selected validation samples were used to test the prediction accuracy of the calibration model.The mean relative deviation between predicted values and measurements was less than 5%.The satisfying results indicated that FT-NIR could be used as a viable alternative to traditional wet chemical method to simultaneously analyze the component in tobacco.The utilization of FT-NIR as a quality control method will enhance efficiency for tobacco prescription design and cigarette quality control.
