| Abstract Scope |
Cassava starch has good film-forming ability, producing films with mechanical properties and appearance suitable for some uses. However, its hydrophilic nature makes it sensitive to moisture and prone to microbial degradation. Adding plasticizers, polymers, and organic compounds to the film-forming solution can reduce these issues. This study examined the effect of adding oil from the larvae of the beetle Speciomerus ruficornis Germar on starch-based film properties. Formulations included PVA (polyvinyl alcohol) as a control, commercial starch, various oil concentrations, and starch-oil blends. The films were tested for tensile strength, moisture content, and solubility according to technical standards. Results showed that oil addition improved film properties, especially moisture resistance and structural integrity, aligning with literature findings. These improvements make the films promising candidates for sustainable applications. |
