标准范围

本文件规定了一种测定即食产品中含有0.03 g/100g至5.0 g/100g果聚糖的婴儿配方奶粉和成人营养品（粉末和液体）中菊粉型果聚糖（包括低聚果糖、低聚果糖）的方法。该方法已在一项多实验室研究[1]中得到验证，其中复溶标准参考材料(SRM)、0,204 g/100g水平的婴儿/成人营养配方奶粉、1.28 g/100g和2.67 g/100g水平的成人营养配方奶粉(RTF)、0,300 g/100g水平的婴儿配方奶粉RTF、0,209 g/100g至0,275 g/100g水平的复溶后续配方奶粉、0,030 8g/100g至0,264 g/100g水平的复溶婴儿配方奶粉。在单个实验室验证研究[2]期间，加标-在重构的婴儿配方奶粉（基于牛奶、基于部分水解的牛奶和基于大豆）、成人营养RTF和重构的成人营养奶粉中进行了高达5g/100g的回收率实验。

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.
