摘要
Abstract
Objective] To rapidly detect the starch content in tobacco.[Method] Near infrared (NIR) diffuse reflectance spectrometer was used to scan 140 samples of flue-cured tobacco leaves.Starch content was detected by continuous flow method .Spectrogram was processed by various parameters method.Finally,constant elimination method was used for pretreatment of spectrum ,and partial least squares method was used to fit the data.The NIR prediction model of starch in flue-cured tobacco was established.And external validation was carried out for these models.[Result] The average relative deviations between the prediction value of starch and the detection value by continuous flow method were less than 5% with RSD smaller than 5%.[Conclusion] The model is applicable to rapid detect the starch in tobacco samples,which is of important practical signifi-cance to control the starch transformation in tobacco curing process and the starch content in tobacco products .关键词
