摘要：

Inadequate mechanical stretching, poor barrier performance, and easy microbial breeding of soy protein isolate (SPI) and chitosan (CS) composite film limit its application. Inspired by the mussel phenolic-protein structure, novel cross-linked nanoparticles (U/SPI/Ag) were first fabricated to graft 3-ene urushiol (3-U) and Ag+ into SPI through laccase-oxidation. Then, it was blended with appropriate amounts of CS to prepare facile and sustainable composite films (CMs). The covalent binding rate of 3-U to SPI was 69 %-76 % by laccase-oxidation. Moreover, 3-U partially stretched the polypeptide c...
