This study analyses the effect of lignin extracted from Dominico-Harton banana on physicochemical properties biodegradable methylhydroxyethylcellulose (MHEC) composites. Lignin was obtained by grinding and sieving, followed treatment with sulphuric acid subsequent separation via centrifugation. Films were developed using casting method, incorporating glycerol in a matrix MHEC dissolved distilled water. They characterised according to their physical, barrier, mechanical, optical, antioxidant properties, 2,2-diphenyl-1-picrylhydrazyl (DPPH) 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic (ABTS). The results showed that provides capacity improves mechanical barrier while contributes flexibility biodegradability. These films have dense resistant structure, potential applications food packaging, agriculture, medicine. research highlights use agricultural waste develop sustainable materials as an alternative conventional plastics.
