Thermal and mechanical treatments may affect the structure of hydrolyzed proteins, thus influencing the obtaining of peptides with improved bioactivity. In this work, tila- pia muscle was treated by thermal sterilization or homogenization with ultra-turrax (UT) and hydrolyzed with alcalase to obtain FPHs with antioxidant properties in salad dressing. To evaluate the bioactive potential of FPHs, the acetylcholin...
