Lemon grass Essential oil Incorporated Starch Based Active Packaging Film, Characterization and Applications

These biodegradable films are typically composed of polysaccharides, proteins, lipids, or there is a growing interest in edible films for fruits and vegetables, driven by concerns over the negative impact of traditional packaging materials on health and the environment their combinations. In this study, edible film was formulated using kidney bean starch, both in its native and nano forms, with the incorporation of lemongrass essential oil. The starch, which can be sourced from various biological origins, served as the primary matrix, while the essential oil contributed its well-known antioxidant and antimicrobial properties. An acid hydrolysis technique was used to decrease the kidney bean starch's granule size and produce nanoparticles in order to improve the starch's qualities. When the physicochemical properties of native and nano starches were compared, it was found that the nano starch had better solubility, swelling power, and the ability to absorb water and oil. According to the results, kidney bean starch may be used for producing packaging films, and adding nano starch to the film formulations can enhance the functional qualities of the finished product.
