In the current study gelatin was recovered from scales of farmed sea bass (Dicentrarchus labrax). The first part of the study was planned to determine the yield of acid-soluble collagen and pepsin-soluble collagen from the scales. Both collagens were characterized as type I collagen, containing a(-1) and a(-2) chains. In the second part, gelatin was extracted using acetic acid and functional properties were determined in this product. Gelatin protein value was found to be 96% and the yield was found to be 18.49%. Proline and hydroxyproline values in the amino acid were found to be high. The gel strength of gelatin was 305 g and viscosity of the gelatin was 33 cP. The gelatin was identified as type A gelatin due to its properties. Fourier transform infrared spectroscopic analysis showed the characteristic similarities of gelatin produced from sea bass scales and calf skin.
