Determination of the quality of high-moisture wheat using near-infrared spectroscopy (Part 1) --determination of moisture and protein content in high-moisture wheat-

摘要

It has been difficult to make an accurate measurement of the moisture and protein content of wheat whose moisture content varies widely during drying and processing. In this study, we used near-infrared spectroscopy, to investigate the accuracy of the measurement for moisture content of wheat in the drying process. Then, we investigated the accuracy of measurements of moisture and protein content of wheat at drying and processing facilities. We found that we could measure both constituents with high accuracy when materials were prepared as high and low moisture wheat with a dividing line of 18% moisture content. The accuracy of wheat moisture content measurement in the drying process was SEP=0.48% and SEP=0.32% for high and low moisture materials, respectively. At processing, the accuracy of the measurement of moisture content was SEP=0.4l% and SEP=0.ll% for high and low moisture materials, respectively, and for protein content it was SEP=0.l3% for both types of materials.
