Utilization of Gelatin and Collagen Extracted from Skate (Raja Kenojei) Skin [PDF ebook] 

Collagen and gelatin are a fibrous protein with a broad range of industrial applications employed worldwide. Gelatin is obtained by the partial hydrolysis of collagen contained in the skin, connective tissue and bones generated as waste during animal slaughtering and processing. It improves the functional properties of food products and may also be used as antioxidative and antimicrobial peptide. Gelatin is widely used in many industrial fields, such as food, pharmacy and photography, and cosmetic materials. Other sources of gelatin and collagen are becoming increasingly relevant, such as fish bones and skins. This new book presents current research in the study of the utilization of collagen and gelatin extracted from skate skin.
