Abstract
The demand for halal gelatin is increasing, but the supply is decreasing. One solution to this problem is to produce halal gelatin from fishing waste, particularly catfish skin. A study was conducted to determine the impact of adding acid to the gelatin extraction process. Citric and acetic acid were used at concentrations of 0.05%, 0.075%, and 0.1%. The yield of gelatin varied from 14.97% to 24.1% depending on the concentration of acid used. The highest yield was obtained using a concentrated solution of acetic acid. Gelatin extracted using a citric acid concentration of 0.075% had the lowest water content. The pH of the solution ranged from 4 to 5, and the viscosity ranged from 10 to 14 MPa. The resulting gelatin exhibited a strength of between 200 and 259 blooms. The production process that used acetic acid on immersion was the most efficient because it resulted in high quantities of gelatin, low water content and viscosity, and good gel strength.
