Biodegradable biopolymers from species of the animal kingdom or their byproducts are sustainable as ecological materials due to abundant supply and compatibility with environment. The research aims obtain a biodegradable active material chitosan, gelatin, collagen bocachico scales (Prochilodus magdalenae). Regarding methodology, films were developed magdalenae) at different concentrations using glycerol plasticizer citric acid cross-linker. obtained hydrated mass processed by compression molding characterized according humidity, water solubility, contact angle, mechanical properties, structural properties. results showed hydrophobic characteristic. First, chitosan-collagen (CS/CO) yellowish color, while gelatin-collagen (Gel/CO) transparent less soluble than films. Concerning gelatin higher stiffness tensile strength chitosan Furthermore, in morphological analysis, more homogeneous increasing concentration acid. In general, extracted an alternative application food industry.
