Cassava Starch-Based Composite Reinforced with Coconut Mesocarpfibers: Analysis of Physicochemical Stability

In one of our previous articles, we developed a cassava starch material reinforced with coconut mesocarpfibers. Its properties have been evaluated. It appears that the behavior composite depends on atmospheric conditions exposure. The purpose this work is to do more in-depth physicochemical stability analysis. To this, identical samples were exposed in different chemical environments: basic, saline, acidic and distilled water. mass losses are measured after 75 days immersion solutions three cases: films without addition lime fibers, film presence reinforcements, finally fibers. We observe that, all cases, loss decreases However, basic solution, decrease greater (53.4%) while it remains acceptable saline environment (1.1%). short, can be used for several applications field packaging such as preservation dry salty products.
