Constructing Rapid and Undamaged Detection Models for Main Physicochemical Indexes of Brewing Sorghum Based on Near Infrared Spectrum

  • 摘要: 为满足对于酒用高粱直链淀粉、支链淀粉、蛋白质、脂肪、单宁含量快速检测的需求,本文采用17种光谱数据预处理方法和4种波段挑选算法建立了这些指标的近红外光谱分析模型。结果表明,各指标最佳光谱预处理方法分别为一阶导数+多元散射校正+Z-score标准化、矢量归一化+均指中心化、标准正态变量变换+Z-score标准化、多元散射校正、标准正态变量变换+Z-score标准化,预测直链淀粉、支链淀粉、蛋白质、单宁含量最佳的波段挑选方法为蒙特卡洛-无信息变量消除,脂肪为竞争自适应重加权采样法。整粒高粱这5项指标最优模型的决定系数(R2)分别为0.9560、0.8765、0.9069、0.8658、0.8841,交叉验证均方根误差(RMSECV)值分别为1.3222、2.3477、0.3549、0.2164、0.1077,外部独立样品验证结果显示模型预测准确率高。本文所建立的近红外分析模型可为酿酒行业实现对高粱的快检提供技术参考。
