In these studies, α-LA appeared to bemore resistant to gastric digestion by pepsin when it was adsorbed andlocated at the oil–water interface than when it was in solution. Underhigh-pressure treatment, α-LA is considerably more stable to denaturation than β-LG; denaturation of α-LA starts to occur only at pressures>400 MPa and reaches 72% after 30 min at 800 MPa (Huppertz et al.,2004).
