Characterization of Fish Gelatin Obtained from Atlantic Cod Skin Using Enzymatic Treatment.

In recent years, there has been increased interest in the production of gelatin from alternative sources, such as raw fish materials. Traditionally, gelatin is obtained using an acidic or alkaline treatment. However, these methods have some disadvantages, such as the long times for processing raw materials and the use of large amounts of water and chemicals.

Chemical Characterization of Atlantic Cod () Collagen Hydrolyzed Using Enzyme Preparation Derived from Red King Crab () and Its Potential as a Core Component of Bacterial Culture Medium.

The Atlantic cod () and red king crab () processing wastes are massive and unutilized in the Murmansk region of Russia. The samples of skin-containing waste of Atlantic cod fillets production were hydrolyzed using enzyme preparations derived from red king crab hepatopancreases, porcine pancreases, and bacteria. The activity of enzymes from crab hepatopancreases was significantly higher than the activity of enzymes derived from other sources.
