From Food Waste to Edible Packaging: Development and Characterization of Biodegradable Gelatin Films with Microfibrillated Cellulose from Cowpea Pod Skin (Vigna unguiculata) and Corn Straw (Zea mays)

This research focused on the development and characterization of gelatin-based films incorporated with cellulose microfibrils (CMFs) extracted from cowpea pod skin (Vigna unguiculata, CPMC) and corn straw (Zea mays, CSMC). The use of CPMC to produce gelatin films has not been previously reported in the literature. Eleven formulations were prepared based on a 22 factorial design with four axial and three central points, in addition to a control film (FC) composed of 1.00% gelatin and 1.00%...
