A calibration model was developed by combined use of the data of amylose content predicted by the NIR spectrometer and color information obtained by the VIS segregator (NIR&VIS) by using multiple linear regression method (dual-step calibration method). The validation statistics between reference amylose content and NIR&VIS-predicted amylose content indicated that the calibration model can be used for screening of rice sample according to amylose content.The validation rice sample set was isolated from calibration rice sample set in this study. The validation set included rice samples of next year products compared to the calibration set. This is the same condition in practical use of this non-destructive method at grain elevators. The results indicated that the combined use of an NIR spectrometer and a VIS segregator enables reasonable non-destructive determination of amylose content of rice at grain elevators.

利用近红外光谱仪预测的直链淀粉含量数据和VIS分选仪（NIR&VIS）获得的颜色信息，采用多元线性回归方法（双步定标法），建立了一种联合定标模型。参考直链淀粉含量与nir&vis预测直链淀粉含量之间的验证统计表明，该校准模型可用于根据直链淀粉含量筛选大米样品。本研究将验证稻米样本集从校准稻米样本集中分离出来。验证集包括与校准集相比的明年产品的大米样品。这种非破坏性方法在谷物升降机的实际应用中也是如此。结果表明，采用近红外光谱仪与VIS分离仪相结合的方法可以合理地无损地测定稻谷中直链淀粉的含量。
