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 0,2Â g/100Â g to 3,0Â g/100Â 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 0,236Â g/100Â g, 0,594Â g/100Â g, 0,616Â g/100Â g and 0,688Â g/100Â g and infant formula RTF at levels of 0,316Â g/100Â g and 0,858Â g/100Â g. During the single laboratory validation study[1] spike-recovery experiments were performed up to 3Â g/100Â g in reconstituted infant formula powders (milk-based, partially hydrolysed milk-based and soy-based), and reconstituted adult nutritional powders.
