摘 要：
本文论述了采用近红外光谱漫反射技术检测葡萄糖浆中主要成分含量的方法。讨论了采用偏最小二乘法(PLS)建立校正模型过程中样品预处理及利用常规吸收峰优选波长的方法。经验证:DE、DP分布测量值同浓度参考值具有良好相关性(相关系数大于0.9),测量重复性变异系数(CV)优于2%。结果表明:近红外光谱法可以满足葡萄糖浆中主要成分的实际测量要求,为玉米深加工企业提供了淀粉糖生产过程控制的参考方法。

摘 要：
The method of assay of principal constituents of Glucose slurry by r eflectance technicology of Near-infrared spectroscopy has been expounded in thi s thesis. The authors has described the pre-treatment way of sample during the period of setting regression models by partial least-squares(PLS) and the way o f wavelength optimum selection according to normal absorbing peak .It's test a nd verified that the measuring value of DE and DP has a good correlation betw ee n prediction values with reference values (correlation coefficient is higher th an 0.9), In addition,the results were reliable with coefficient of variation (CV ) of repeatability below 2 percent. Therefore, Near-infrared spectroscopy o f r eflectance technicology could meet practical measurement accuracy as require d fo r principal constituents of Glucose slurry. This study provided a new refer ence method to control starch-sugar procedure for those companies engaged in d eep-process industry.
