婴儿配方食品和成人营养品.果聚糖的测定.酶处理后脉冲安培检测的高效阴离子交换色谱法（HPAEC-PAD

[中文适用范围]： 本文件规定了一种测定婴儿配方奶粉和成人营养食品（粉末状和液体）中菊粉型果聚糖（包括低聚果糖、果寡糖）的方法。这些产品中的果聚糖含量为0,03 g/100 g至5,0 g/100 g，以准备好的即食形式测定。 该方法已在多家实验室的研究中使用重构的标准参考材料（SRM）、婴儿/成人营养配方奶粉在0,204 g/100 g水平、成人即食营养品（RTF）在1,28 g/100 g和2,67 g/100 g水平、婴儿配方奶粉RTF在0,300 g/100 g水平、后续配方奶粉重构在0,209 g/100 g至0,275 g/100 g范围，以及婴儿配方奶粉重构的范围从0,030 8 g/100 g到0,264 g/100 g。 在单实验室验证研究[2]中，在牛奶基、部分水解牛奶基和大豆基婴儿配方奶粉粉末、成人即食营养品和重构成人营养奶粉中进行了加标回收实验，直至5 g/100 g。 [外文原描述]： This document specifies a method for the determination of inulin-type fructans (including oligofructose, fructooligosaccharides) in infant formula and adult nutritionals (both powder and liquid) containing 0,03 g/100 g to 5,0 g/100 g of fructans in the product as prepared ready for consumption. The method has been validated in a multi laboratory study [1] with reconstituted standard reference material (SRM), infant/adult nutritional formula at a level of 0,204 g/100 g, adult nutritionals ready-to-feed (RTF) at levels of 1,28 g/100 g and 2,67 g/100 g, infant formula RTF at a level of 0,300 g/100 g, reconstituted follow-up formula at levels of 0,209 g/100 g to 0,275 g/100 g, reconstituted infant formula at levels from 0,030 8 g/100 g to 0,264 g/100 g. During the single laboratory validation study [2] , spike-recovery experiments were performed up to 5 g/100 g in reconstituted infant formula powders (milk-based, partially hydrolysed milk-based and soy-based), adult nutritional RTF and reconstituted adult nutritional powders.
