Infant formula — Determination of ?-galactooligosaccharides — Ultra high performance liquid chromatography (UHPLC) with fluorescence detection after pre-column derivatization

This document specifies a method for the determination of ?-galactooligosaccharides (GOS) in infant formula (both powder and liquid) containing 0,2?g/100?g to 3,0?g/100?g of GOS in the product as prepared ready for consumption.

The method has been validated in a multi-laboratory study with reconstituted infant formula at levels of 0,236?g/100?g, 0,594?g/100?g, 0,616?g/100?g and 0,688?g/100?g and infant formula RTF at levels of 0,316?g/100?g and 0,858?g/100?g. During the single laboratory validation study^[1] spike-recovery experiments were performed up to 3?g/100?g in reconstituted infant formula powders (milk-based, partially hydrolysed milk-based and soy-based), and reconstituted adult nutritional powders.
