| Abstract: | 穀物共同乾燥調製施設での自主検査における実用的な使用を想定し, 市販の近赤外透過型分析計による米の成分測定の精度を検証した。さらに分析計のフィルタ部およびキャリブレーションの改良をおこない, 測定精度の向上を試みた。その結果, 水分の測定精度は決定係数 (r2) が0.98, 標準誤差 (SEP) が0.13%, バイアス (Bias) が-0.02%であり, タンパク質の測定精度はr2=0.90, SEP=0.17%, Bias=0.01%であった。すなわち, 水分とタンパク質の測定値は基準分析に換えて利用できる良い精度であった。この分析計は, 温度が10℃から30℃までの範囲の玄米, および籾混入率が10%以下の玄米に対して, 水分とタンパク質を精度良く測定することが可能であった。 | | The accuracy in determination of rice constituent contents using near-infrared transmission (NIRT) spectroscopy was validated. A commercial NIRT spectrometer, which was considered to be applicable to practical use for quality inspection at a rice grain elevator, was used in this study. The accuracy of the spectrometer improved after modifying light filters and calibration models. In the determination of moisture content, the coefficient of determination (r2) was 0.98, standard error of prediction (SEP) was 0.13%, and bias was -0.02%. In the determination of protein content, r2 was 0.90, SEP was 0.17%, and bias was 0.01%. These results proved that the spectrometer was sufficiently accurate to be used instead of reference analysis for measuring moisture content and protein content of brown rice. The spectrometer could be also used with sufficiently high accuracy at a grain elevator for samples in a temperature range of 10°C to 30°C and for samples with a rough rice percentage of less 10%. |
