Protein structure, a lever for infant formula optimisation

Infant formula is the most adequate substitute to human milk; however, although these two infant foods are close in terms of macronutrient content, their fine composition and structure still differ, particularly regarding proteins.

The substitution of bovine whey proteins, generally used for infant formula production, by purified bovine α-lactalbumin and lactoferrin can be a solution to better mimic the human milk protein profile. However, the heat treatments applied during infant formula production for sanitary reasons, modify the protein structure, which could alter their digestion. The objective of the present study was to evaluate the heat treatment impact, combined to different whey protein profile, on the protein structure within model infant formulas and, in turn, on their in vitro digestion.
