Total amino acid (TAA) accumulate release expressed as a percentage of final TAA release over 32 h via in vitro digestion. Digestion was recorded between −4 and 0 h by pepsin digestion and between 0 and 28 h by trypsin digestion. N.CAS = diet with casein at normal protein levels; L.CAS = diet with casein at low protein levels; N.CGM = diet with corn gluten meal at normal protein levels; L.CGM = diet with corn gluten meal at low protein levels.
