To improve the overall performance of soybean protein isolate (SPI)/sodium alginate (SA) complex films, an Antheraea pernyi silk sericin (APSS)/SPI/SA ternary blend-based film was prepared using different amounts of APSS. The effects of APSS on the mechanical, water-blocking, microstructural, and antioxidant properties of the complex films were investigated. APSS was found to improve the opacity and reduce the solubility and water vapor permeability (WVP) of the complex film. A ternary complex film with 2 % APSS had the best mechanical strength, chrominance, solubility, WVP, and contact angle properties. APSS addition enhanced the free radical-scavenging ability of the film in a concentration-dependent manner. Compared with the film without APSS, 8 % APSS increased the free radical-scavenging rates of ABTS· and DPPH by 2.56- and 2.59-fold, respectively, retaining a high level after digestion simulation in vitro. These properties make APSS/SPI/SA ternary blend-based films useful for food preservation and packaging applications.
