This standard gives guidance for the quantitative determination of melamine and cyanuric acid content in milk

Prevention of the development of chlorate in the dairy chain (Bulletin of the IDF n° 526/2023)

as a percentage by mass

The determination is performed by direct transesterification in food matrices

ISO 7102 | IDF 257: 2024 — Infant formula — Determination of β-galactooligosaccharides — Ultra high performance liquid chromatography (UHPLC) with fluorescence detection after pre-column derivatization Language:EN Associate ProfessorThis 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
