N2 - In response to global food security challenges, this study pioneers the integration of photocatalytic H2 production technology with bio-based materials, establishing an innovative approach for fruit preservation. An efficient photocatalyst, Pt/CN-HT, was prepared by protonation, heat treatment and Pt modification. A multifunctional bio-nanocomposite film (FSG/CS/Pt/CN-HT) was constructed by introducing this catalyst into fish scale gelatin/chitosan (FSG/CS) matrix. Material characterization demonstrated well-rounded functional characteristics of the film, such as excellent antioxidant activity (87.4 % DPPH radical scavenging capacity), highly efficient antimicrobial (against both E. coli and S. aureus and B. cinerea), mechanical robustness (25.8 MPa tensile strength), barrier properties of 23.8 % reduction in water vapor transmission rate coefficient and 33 % decrease in oxygen permeability and comprehensive biosafety compliance. A synergistic ‘endogenous regulation-exogenous protection’ preservation system was constructed by combining photocatalytic H2 with FSG/CS/Pt/CN-HT composite film treatment using tomato and kiwifruit as models. The results showed that the photocatalytic H2 significantly inhibited ethylene biosynthesis by down-regulating the activity of ethylene synthase, while the FSG/CS/Pt/CN-HT composite film extended the shelf life of the fruits to 15 days by regulating the microenvironment of storage. This groundbreaking application of photocatalytic H2 technology in postharvest fruit preservation not only addresses the limitations of traditional methods but also provides a sustainable and innovative solution for the green preservation of perishable agricultural products.
