Abstract: The utilization of waste shells from Aegle marmelos (bael) as a source of Micro fibrillated cellulose (MFC) was undertaken for applications in food packaging within the framework of this investigation. FTIR analysis of CAM and Raw Aegle marmelos shell powder (RAM) showed stretching of –OH and –CH groups at 3339 cm −1 and 2889 cm- 1 . Our results showed that crystallinity indices of CAM and RAM were 39.59 % and 18.89 %, respectively indicating a significant raise in crystallinity after extraction. FTIR analysis reveals the presence of hydroxyl groups (3306 cm −1 ) in all films. Exploration of the results indicated the development of covalent and H (hydrogen) bonds between CAM and Guar gum/Chitosan (GT), as discerned through FT-IR studies. X-ray diffraction unveiled in the amorphous feature of the films following CAM into GT composite film . Evaluation through FE-SEM exhibited a densely disordered network contributing to a heightened contact angle of the resultant film with an enhanced concentration of CAM. Cellulose Iβ and Chitosan showed stronger binding affinity of −7.3 kcal/mol, suggesting greater compatibility and stability. The antioxidant capacity of the films increased from 10.90 to 61.80 due to addition of CAM in the GT mixture where elevated concentrations demonstrated better scavenging activity.
