Unripe banana starch

Growing interest in the creation of biodegradable composites is a result of the growing demand for sustainable substitutes for synthetic polymers. The main aim of this study is to characterize and contrast biodegradable composites composed of unripe banana starch reinforced with pineapple leaf fiber. Two composite formulations were created: Sample B (10 g of unripe banana starch, 5 mL of glycerol, 100 mL of distilled water, and 5 g of fiber) and Sample A (10 g) of unripe banana starch, 5 mL of glycerol, 100 mL of distilled water, and no added fiber). 

The development of biodegradable composites has gained significant attention due to the environmental concerns associated with synthetic polymers. Unripe banana starch, characterized by its high amylose content, presents excellent film-forming properties and biodegradability, making it a promising matrix for composite fabrication. Despite these advantages, its poor mechanical properties restrict its standalone use in structural applications. To improve its performance, reinforcement with natural fibres such as pineapple leaf fibres has been explored.
