摘 要：
采用近红外光谱分析技术,结合改进最小二乘回归法(MPLS),以40个不同来源的豆粕饲料样品建立豆粕蛋白质含量分析的预测模型。模型定标相关系数(RSQ)为0.916 0,定标标准差(SEC)为0.150 3,交互验证标准差(SECV)为0.324 2。试验表明,利用近红外光谱分析技术可以比较准确地定量检测豆粕中蛋白质的含量。

摘 要：
Based on the near-infrared reflectance spectroscopy(NIRS) method and modified partial least squares(MPLS)regression method, a prediction model for determination of protein content in soybean meal was established using 40 soybean meal feed samples from different origins. The results showed that the R square(RSQ) of the calibration model was 0.916 0, the standard error of calibration(SEC) was 0.150 3, and the standard error of cross validation(SECV) were 0.324 2. These data suggest that the established NIRS method is an effective technology for the quantitative determination of protein content in soybean meal.
