Infancy is a time of rapid growth, when consuming protein of appropriate quality and in sufficient amounts is crucial for the body to build new tissues 111Nutten, S. (2016). Proteins, Peptides and Amino Acids: Role in Infant Nutrition. Nestle Nutrition Institute Workshop Series. https://doi.org/10.1159/000442697. Cow’s milk protein contains less whey protein than human milk, so it is important to re-balance the casein:whey protein ratio in infant milk formula recipes. Demineralised whey is widely used in infant milk formula to simultaneously adjust the casein:whey ratio, while limiting mineral contribution providing flexibility in meeting legislative mineral profiles.
