Rapid Determination of Lignin Content in Henan Tobacco Leaves by Near Infrared Spectroscopy
摘要
Abstract
Objective] To realize the repaid prediction of lignin content in tobacco leaves of Henan Province .[ Method] Determination meth-od of lignin content in tobacco leaves was improved and the accuracy of the method was evaluated ( for the same sample , the RSD value of 8 parallel tests was 3.58%).The lignin content in 95 samples of early baked tobacco leaves in Henan Province was determined by this method. Then, corresponding spectra were collected by the near infrared spectrometer.After the second order differential treatment and smooth pre-treatment, corresponding prediction model were established by partial least square method and fully interactive authentication method.[Re-sult] The correlation coefficient of lignin prediction model was 96.13%, RMSECV was 0.104.[ Conclusion] There is good correlation be-tween lignin content and near infrared spectrum, and the lignin content in Henan tobacco can be predicted by near infrared spectroscopy.关键词
