In order to improve the poor mechanical properties and strong hydrophilicity of soluble soybean polysaccharide (SSPS) based films, licorice residue extract (LE) was introduced into the film-forming matrix. In this study, the effect of the amount of LE on the microstructure, physical and functional performances of the SSPS-based films, and its antioxidant activity and practical application in delaying the oxidation of oil-fried peanuts were investigated. The results showed that the compounding of LE increased the tensile strength (TS) by 4.39 times, decreased the WVP to 62 %, and increased the contact angle by 17.77 %, respectively. FTIR and SEM analyses verified the formation of intermolecular hydrogen bonds among LE, glycerol and SSPS. Furthermore, radical scavenging activity experiments proved that the films possessed a superior capacity to scavenge DPPH and ABTS
