Fortification of fermented soy milk using whey protein isolate/gelatin microhydrogels-loaded with sesame bioactive peptides.

ABSTRACT: Sesame seed protein isolate (SSPI) and hydrolysate (SSPH) were encapsulated in microhydrogels made of gelatin (GL) and whey protein isolate (WPI) at varying concentrations. The study assessed encapsulation efficiency (EE), swelling degree (SW), and antioxidant activity. The best microhydrogel, with the highest EE (84.20 % ± 0.24 %, significantly higher than other treatments, P < 0.05), SW (31.67 % ± 0.16 %, P < 0.05), and radical scavenging activities (DPPH: 83.28 %, ABTS: 85.73 %), was formed with 3 % GL, 5 % WPI, and SSPH (100 μg/mL), designated as T8. This formulation showed superior antioxidant properties compared to SSPI. T8 had a particle size of 1094 nm, a surface charge of -40.5 mV, and a denaturation temperature of 91.52 °C. Its controlled release of SSPH in stomach
