Discovery of superior bioactive peptides of two edible Lentinus mushrooms protein hydrolysate in biological activities: tyrosinase inhibitory and antioxidant activity

This study investigated protein hydrolysates obtained from Lentinus squarrosulus and Lentinus edodes fruiting bodies via gastric protease hydrolysis and ultrafiltration, yielding peptides with a molecular weight below 6.5 kDa. These hydrolysates displayed significant tyrosinase inhibitory activity similar to positive controls, peptide from Chinese quince seed (RHAKF) and kojic acid. L. squarrosulus-derived hydrolysates exhibited superior antioxidant properties compared to L. edodes in DPPH (47
