description The utilization of sericin should be expanded to increase the availability of silkworm silk. However, the poor mechanical properties and susceptibility to moisture of sericin have continuously restricted its use. In this study, a facile crosslinked sericin film was prepared using a glucose-induced Maillard reaction, and the physicochemical properties and antioxidant functionality of the crosslinking reaction were investigated. The glucose-induced Maillard reaction can be conducted in an environmentally friendly manner through a simple heat treatment of sericin at 90 °C, and the degree of crosslinking can be adjusted by controlling the amount of added glucose. The glucose-induced Maillard reaction improves the mechanical properties of the sericin film, reduces its vulnerability in a moist environment, and provides UV protection and improved antioxidant activity. [Display omitted] •Using glucose as an eco-friendly crosslinking agent, a Maillard-reacted silk sericin film was successfully fabricated.•The Maillard reaction between sericin-glucose effectively improved the structural integrity of the sericin film.•The glucose-crosslinked sericin films exhibited enhanced UV-blocking and antioxidative properties.
