Abstrakt: In this study, we developed active bio-composite films using a sodium alginate/starch (1:1) matrix incorporating date seed extract encapsulated mesoporous silica (DSE@MCM-41) up to 7.5 wt%. Incorporating DSE@MCM-41 significantly improved the films' properties, enhancing antioxidant efficacy and UV-blocking capabilities. Notably, the films exhibited a 29.5 % increase in tensile strength, a 34.81 % decrease in water absorption, and a reduction in water vapor permeability to 1.76 × 10 -8  g m -1 .h -1 .pa -1 at 5 wt% DSE@MCM-41 concentration. These enhancements, coupled with sustained DSE release, effectively extended the shelf life of black grapes by up to 16 days. These results demonstrate the potential of DSE@MCM-41-incorporated bio-composite films to improve food preservation and extend shelf life, making them suitable candidates for advanced food packaging systems.
