The effect of microwave, ultrasound and high-pressure pre-treatment prior to enzymatic hydrolysis of mechanically deboned chicken residuals was evaluated. Increased protein extraction yield was observed for high-pressure pre-treatment at ≥400 MPa. Enhanced antioxidant activity was found in hydrolysates pre-treated with high-pressure (200 MPa) and ultrasound (900 W). Hydrolysates with higher protein solubility over pH were found after pre-treatments at 200 and 600 MPa, and 1 and 10 min microwave at 40 °C, with the most efficient option being the shortest microwave treatment. Furthermore, pre-treatments with ultrasound at 600 W, microwave for 1 min at 40 °C, and high-pressure at 200 MPa seem to have the potential to induce formation of peptides with higher lipid associating properties.
