| Abstract: | Selection of 105 representative active meters sample , the spectral 12 points within the range of 918~1045 nm band correlation of near infrared spectral reflectance and its quality .Based on the near infrared spectrum data from the desktop grain analyzer for multiple linear regression , Principal component regression and partial least squares calibration model results are compared to establish activity γ-aminobutyric acid, water ,protein, starch ,lightness value degree ,red value degree ,yellow value degree value best correction model of near infrared spectrum , forecasts determine coefficient were 0.903,0.964,0.953,0.951,0.949,0.961,0.916,the predicted standard deviation were 0.598,1.367, 1.367, 2.688, 0.996, 50.144, 0.952.Test results show that application of near infrared spectroscopy detection activity of rice quality is feasible . |
