| 摘 要： | 近红外光谱分析技术是近年来发展起来一种新的分析技术,能简单、快速、准确地测定有机物中的化学成分。将其与传统分析方法测定面粉中粗蛋白和粗灰分进行比较,统计结果表明,二者相关系数r分别为0.986和0.991,相对误差均小于5%,说明可以用近红外光谱分析技术进行面粉粗蛋白和粗灰分的测定。

| Abstract: | As a new analytic technique with simpleness,speediness and exactness,near infrared spectroscopy(NIR) is increasingly used in many fields.This new technique was compared with traditional technique in measuring crude protein and crude ash of flour in this article.The results showed that using the two methods to measure crude protein and crude ash,correlation coefficients r were 0.986 and 0.991 respectively,relative errors were both lower than 5%.NIR could be used to measure the contents of crude protein and crude ash in flour. |
