Influence of Protein Hydrolysis on Dietary Protein Digestibility and Metabolism in Healthy Subjects
April 1, 2009 updated by: Institut National de Recherche pour l'Agriculture, l'Alimentation et l'Environnement
Hydrolysis of dietary protein may impact their gastrointestinal kinetics and further metabolism.
The primary goal of this work was to measure the metabolic fate of intact or hydrolyzed protein using a protein of good nutritional quality, i.e., casein.
A second aim of this study was to assess the true ileal digestibility of dietary protein using different methods including the hydrolyzed casein method and to measure its possible effect on endogenous intestinal N losses in humans.

EXPERIMENTAL: Intact casein
Subjects undergo an intestinal and metabolic exploration following the ingestion of a standard mixed meal containing 15% of energy as 15N-labelled intact casein

Subjects are studied for 8h following the ingestion of a standard meal containing 15% of energy as protein.
Intestinal, blood and urine are collected at regular intervals.
