Rapid Determination of Polyphenols in Tobacco by Near Infrared Reflectance Spectroscopy

Correlation models for determination of polyphenols based on near-infrared(NIR) reflectance spectrum of 244 representative tobacco samples selected from 340 samples was established.The predicted results of 20 samples showed there were not markedly difference between predictive data and actual data.The mean deviation is 0.10.The NIR analysis technique is simple,fast,low cost,without pollution,non-destructiveness sample,and can be used for quantitative analysis of polyphenols of tobacco.
