Abstract
[Objective] To establish near-infrared quantitative model for detection of water-soluble sugar and nicotine in flue-cured tobacco.[Method] Based on near-infrared spectroscopy, a total of 284 samples were selected, and partial least squares (PLS) model was used to establish model, soluble sugar(total sugar, reducing sugar) and nicotine content in tobacco in Guizhou were quantitatively analyzed, the spectral range was determined as 9 002.45-4 069.19 cm-1, spectral pretreatment was conducted by using first-order derivative and Savitzky-Goly (SG) smoothing filter.The precision of the model was investigated, the results obtained by standard method and near-infrared method were compared.[Result] The correlation coefficients of total sugar, reducing sugar and nicotine in tobacco were 0.996 8, 0.987 2, 0.995 1, RMSECV were 0.354, 0.558, 0.067 respectively.[Conclusion] The precision of the model is good, and there is no significant difference between the two methods.The near-infrared method is suitable for the rapid quantitative analysis of water-soluble sugar and nicotine in tobacco.关键词
