Gelatin production from fisheries wastes in iran: qualitative and quantitative properties

Gelatin is a water soluble, hydrophilic derived protein which causes it to have useful functional properties such as colloidal dispersion in water, and hassiveness and gel strength in food systems. High amounts of fishes and sharks and also wastes products obtained from fishes processing factories were used in south region of Iran. In this project the use of fishes wastes of the Persian gulf for production of gelatin was studied with two methods of alkaline and acidic. The results obtained showed that the alkaline procedure gave high yield in gelatin production from fishes wastes. Produced gelatin was compared to purchased commercial gelatin from India. The comparison results does not show any significant difference.
