Milk-based infant formula powders — Quantification of whey protein content by sodium dodecyl sulfate-capillary gel electrophoresis (SDS-CGE)

Formules infantiles en poudre à base de lait — Quantification de la teneur en protéine de lactosérum par électrophorèse capillaire sur gel contenant du dodécylsulfate de sodium (SDS-CGE)

Abstract / scope

This document specifies a method for the determination of the whey to casein protein ratio, ranging from 20:80 to 80:20 in cow milk-based infant formula powders.

This method does not apply to the analysis of infant formulas containing hydrolysed protein or proteins from other sources (e.g. plants or milk from other mammals).
