Milkoscan FT 120对原料乳中三聚氰胺快速分析

Quick analysis of melamine in raw milk by Milkoscan FT 120

为了建立一种快速测定原料乳中掺假物质的方法,利用红外光谱,采用主成分分析(PCA)回归方法,以本地区具有代表性原料乳样品集为基础建立标准数据模型。在原料乳中加入三聚氰胺模拟牛奶掺假。通过总结原料乳成分数据的变化规律及调整控制因素以达到预判原料乳掺假和确定掺假物质的检出限的目的。结果表明,该方法具有快速、准确的特点。

In order to establish a method for rapid determining melamine in raw milk,a standard data model was set up on the basis of representative samples of raw milk in Harbin by principal component analysis（PCA） regression method with IR.Melamine was added to raw milk samples for the purpose of simulating adulterated milk.We could predict the adulteration in raw milk and determine the detection limit of adulterated substances by summarizing both the content changes of the ingredient in raw milk and the adjusting control conditions.This method was rapid and accurate.
