a novel biocompatible film incorporating red cabbage anthocyanin extract into tapioca starch/bovine gelatin/zinc oxide nanorod

The advances in the use of new biomaterials capable to improve the shelf life of foods may cоntribute to reduce the food waste problem. the presentation study, the effect of red cabbage anthocyanin extract (rcae) at different amounts (1, 2.5, 5, and 10 v/v%) on the thickness, opacity, moisture content, and antioxidant properties of bionanocomposites film based on tapioca starch/bovine gelatin/0.5 zinc oxide nanorod (zno-n) was studied. the incorporation of rcae up to 10% into the edible film increased the thickness of the film by about 40%, while the moisture content decreased by about 11.5% (p < 0.05). the antioxidant activity of the films increased from 4.74% to 92.28% after rcae loading increased from 0 v/v% to 10 v/v%. with increasing in the rcae content, the opacity of the biocompatible films increased. in summary, the functional characteristics presented that active film containing rcae could be employed as a biodegradable packaging in food industry.
