Angiotensin I-converting enzyme inhibitory properties of lentil protein hydrolysates: Determination of the kinetics of inhibition

► ACE inhibitory properties of lentil protein hydrolysates and kinetics were studied. ► ACE inhibitory activity varied as a function of the type of enzyme used for digestion. ► IC50 values of 0.053 and 0.190 mg/ml were obtained for the different hydrolysates. ► The inhibition mechanism was found to be non-competitive. ► Use of hydrolysates as bioactives rather than purified peptides may be of interest.
