Citric acid crosslinked Carica papaya seeds mucilage-based hydrogel film were synthesized and characterized. The extracted mucilage and hydrogel film were explored by determining their physicochemical, thermal, micrometric and spectrophotometric properties. The results of attenuated total reflectance-Fourier transform infrared spectroscopy and solid state 13C-nuclear magnetic resonance spectroscopy confirms the emergence of ester crosslinking between the mucilage and citric acid. The swelling study of mucilage and hydrogel film revealed good swelling ability of prepared hydrogel film. Also, the hydrogel film showed better thermal stability than the mucilage. The current study showed that papaya seed mucilage can be used as a bio-based source for hydrogel using citric acid as a cross-linker. Further, it can be potentially explored in pharmaceutical, food and cosmetic industries.
