This study assessed the effects of three physical methods-dielectric barrier discharge (DBD) plasma, ultrasound, and heat-moisture treatment-coupled with resveratrol enrichment, on the physicochemical and digestive properties of banana starch. The findings indicated that each physical treatment enhanced the complex index between starch and resveratrol. Scanning electron microscopy and X-ray diffraction analyses revealed that the inherent A-type crystallinity of the starch remained unchanged after modifications. Heat-moisture treatment induced the most profound alterations in the long-range and short-range order. While DBD plasma and ultrasound did not affect the granular morphology, heat-moisture treatment caused the most significant disruption. Furthermore, DBD plasma and ultrasound treatments significantly enhanced the solubility, gelatinization temperature, and viscoelastic properties of banana starch, while having a negligible effect on its digestibility. After heat-moisture treatment, banana starch exhibited significantly higher gelatinization temperatures (T
