Abstract

  • Objective: Gelatin is widely used biopolymer in various industries due to its excellent biocompatibility, biodegradability properties. In the present study, gelatin was extracted from fish wastes, as an alternative source.

    Methods: This biopolymer was extracted from the scales of freshwater fish, Labeo rohita. After extraction, the proximate analysis and physico-chemical analysis of the fish scale gelatin were carried out. This functional polymer was also characterized using different analytical methods, such as UV-vis spectroscopy, scanning electron microscopy (SEM), and X-ray diffraction (XRD) for the evaluation of crystalline and surface morphology, and fourier transform infrared spectroscopy (FTIR) for structural determination.

    Results: The scales of L. rohita yield 24% (dry weight basis) of gelatin, indicating this fish species as potential source of gelatin. The proximate analysis determined was low moisture content (4.2%), ash (1.4%) and high protein (90%) content. The result of the study confirms the effectiveness of extraction method used.

    Conclusion: The fish scales of L. rohita are found to be a sustainable and renewable source of gelatin with desirable functionalities and it is the best alternative for mammalian gelatin in food and other industries.
