Fabrication and Characterization of Guar Gum–Chitosan–Polyvinyl Alcohol–Tannic Acid–Silver‐Nanocomposite Films for Extending Fruit Shelf Life
This research presents a sustainable film prepared by the solvent casting method, integrating tannic acid (Tn) into a composite matrix of guar gum, chitosan, polyvinyl alcohol, and silver nanoparticles (GG–CH–PVA–Tn–AgNP) for the preservation of fresh bananas, strawberries, and blueberries. With silver nanoparticles,...
