Digestive proteinases from marine organisms and their applications

Abstract

Fish viscera have wide biotechnological potential as a source of digestive enzymes, especially proteinases. The biological diversity of fish species provides a wide array of enzymes with unique properties. Fish digestive proteolytic enzymes most commonly found include pepsin and trypsin. Those enzymes from fish viscera may have the advantages for the applications in the food industry since their temperature and other characteristics differ from homologous proteinases from warm-blooded animals. Therefore, digestive proteinases can be isolated as a value-added product from fish viscera and used as the processing aids in food industries to maximize the utilization of marine resources.
