The effects of condiment (salt) and processing technic (homogenization) on digestion and interfacial properties of micro/nano-sized colloidal particles (MNCPs) in bigeye tuna head soup (BTHS) using simulated gastrointestinal digestion model in vitro were investigated. For MNCPs in BTHS, the triglycerides

Our previous report showed that yam dioscorin and its peptic hydrolysates exhibit radical scavenging activities; however, the functions of these peptic hydrolases are still under investigation. In this study, the thiol-containing peptides derived from computer-aided simulation of pepsin hydrolysis of
