A novel hybrid protein gel was developed to sustainably meet the growing demands for protein with pea and whey protein isolates (3:2 in 15 % w/v protein content) which was ultrasound treated (7.5 and 15 min), and gelled (90 °C, 60 min). The study investigated the impact of ultrasound treatment on the structure and gastric breakdown kinetics of hybrid protein gels and compared these properties to commercial protein-based foods (ham, paneer, and mozzarella). Ultrasound treatment for 15 min significantly (p <
