Description
Summary:Gouramy (Osphronemus gouramy) bones are wastes that have not been used optimally and contain collagen to produce gelatin. On the other hand, gelatin is a natural product of collagen hydrolysis and a soluble protein that functions as a gelling agent. Generally, the manufacturing process begins by immersing the bones in a strongly acidic solution to dissolve calcium phosphate and other mineral salts. This treatment produces changes in softness for the bones to become relatively soft, using a weak acid CH3CO2H with a concentration level of 5%, 10%, 15%, 20%, and 25%. Therefore, this study aims to determine the quality of gelatin with various concentrations of acetic acid. The results showed that the best treatment to produces gelatin was at a concentration level of 25% of acidic acid, the amount of moisture, ash, protein content, gel strength, viscosity, pH, and yield of 7.2%, 0.65%, 37.40%, 126.98 bloom, 5.60 cP, 5.42%, and 19.3%, respectively.
