Abstract:
The extraction of valuable substances from food production and processing wastes is increasingly feasible with advancements in technology. Mango seeds, often overlooked and wasted after processing, represent a non-traditional source of starch. This study was aimed to explore the potential of mango kernel starch for the production of biodegradable cellulose-starch composite films. The effects of different plasticizers (glycerol, sorbitol, and a combination of both) on the solubility, sorption, mechanical properties, and water barrier characteristics of the composite films were investigated. Despite having qualities comparable to starches from traditional sources, such as wheat, rice, maize, and potatoes, mango kernel starch remains underutilized. Utilizing mango waste, particularly mango seeds, could alleviate the problem of waste disposal and create value-added commercial products. Cellulose, as a reinforcing filler in biopolymers based on starch, has garnered significant interest. The low cost, availability, renewability, and biodegradability of cellulose-based composites make them attractive for the development of structural materials from renewable resources. This research aims to maximize the extraction of high-purity mango kernel starch, evaluate the physicochemical and functional properties of starch films blended with cellulose fibers, and examine the synergistic effect of polyols (sorbitol and glycerol) on the elasticity of cellulose-starch blends. The study demonstrates the viability of mango kernel starch as a material for film formation and highlights the influence of different plasticizers on the mechanical and barrier properties of the films. Films plasticized with glycerol exhibited lower tensile strength but higher solubility, water vapor permeability, and elongation at break compared to those plasticized with sorbitol and a combination of both. The findings indicated that mango kernel starch holds potential for the development of attractive, biodegradable, and edible films.
