Abstract: A method of producing a protein phospholipid complex from a crustacean catch including protein is claimed where hydrolysis occurs without substantially denaturing the protein from the crustacean catch. A method of producing a stable protein phospholipid emulsion from a crustacean catch is also claimed. A method of producing crustacean oil is claimed where the oil is separated from the hydrolyzed crustacean catch. Other methods of producing a protein phospholipid complex are claimed which relate to not removing the shell, removing the shell, and removing then adding back the shell to form the protein phospholipid complex.
