PROBLEM TO BE SOLVED: To provide a method for industrially and productively producing high-quality fish gelatin from fish scales as a raw material. SOLUTION: The method for producing gelatin from fish scales as a raw material comprises the deashing step (a) of deashing fish scales, the acid soaking step (b) of keeping the fish scales after the deashing step (a) immersed in an acid, the extraction step (c) of extracting the fish scales subjected to the acid soaking step (c), the melanin removal step (d) of separating and removing melanin from the extract obtained in the extraction step (c), and the filtration step (e) of filtering the supernatant liquid obtained in the melanin removal step (d). This method can give gelatin excellent in properties such as jelly strength, especially gelatin excellent in transparency. COPYRIGHT: (C)2006,JPO&NCIPI
