Abstract
A texturized sinking shrimp and fish food is produced in the form of an extrusion cooked, cellular produce which is self-sustaining in ambient temperature water for a period of at least four hours and is made up of a mixture of at least 8 percent marine meal with up to 60% vegetable protein flour. The product is prepared by mixing and then partially cooking the starting materials in a preconditioner and then introducing the precooked mixture into an extruder (preferably of the twin screw variety) for texturization. During extrusion, the protein within the mixture is developed into laminar striations, which ultimately yields a layered, open-celled, high protein product having a specific gravity greater than 1.00 which will not readily decompose in water during consumption by the shrimp and fish.
