Bifunctional photocatalyst/hydrogel composites: Synergistic effects and degradation mechanisms for the degradation of benzo(a)pyrene in smoked sausages

Benzo(a)pyrene (B(a)P) is a structurally stable and carcinogenic compound, and B(a)P deposition and transport from smoking environment particulates to smoked meat products is a global challenge. In this study, a novel photosensitive bifunctional composite gel (ST/SiO
