ABSTRACT This study aimed to evaluate the effects of chitosan, extracted from shrimp shells, on engineering, antioxidant, antibacterial, and microstructural properties chitosan–alginate–carrageenan‐based hydrogels. Hydrogels were synthesized with fixed sodium alginate (1.00 g) carrageenan (0.50 while varying chitosan content 0.50 1.50 g (samples M1, M2, M3, M4, M5). Among samples, M3 chitosan) demonstrated optimal performance a tensile strength 5.3 MPa, swelling ratio 1202% (at pH 7) 1256% 11), lowest conductivity (306.2 μS/cm). sample also exhibited highest scavenging activity (94.95%) after 120 h maximum antibacterial efficiency (99.2% against E. coli , 99.0% S. aureus ). Structural characterization revealed that had an amorphous structure confirmed by X‐ray diffraction (XRD), highly porous microstructure (micron‐sized pores) observed via scanning electron microscopy (SEM), facilitating water absorption molecular diffusion. Analysis Fourier transform infrared spectroscopy (FTIR) indicated strong intermolecular interactions through ionic bonds hydrogen bonding among OH, NH, CO, COO − OSO 3 COC groups. These findings highlight potential chitosan‐based natural hydrogels for biomedical, food packaging, environmental applications.
