Abstract: A method of producing a texturized material of a marine product from the "surimi" of the same. It comprises the step of feeding to a twin-screw extruder at least one of the following materials; the material prepared by heat-treatment of the "surimi", the material prepared by addition and mixing of suitable subordinate raw material to and into the "surimi" and subsequent heat-treatment of the resulting mixture, the material prepared by drying, for dehydration, of the "surimi" to make the water content thereof not greater than 70% and the material prepared by gelation of the "surimi" through the setting of the same. It further comprises the steps of treating the at least one material under pressures of 1 to 50 kg/cm.sup.2 and temperatures of 100.degree. to 200.degree. C., by means of the twin-screw extruder, thereby processing it into a texturized material.

Abstract: A process for processing and treating raw materials such as marine products comprising of fishes, shellfishes, such as Crustacea and mollusks, and seaweeds or mixtures of said material and an optional mixing additive such as soyprotein, wheat flour and starch by means of a twin-screw extruder. The extrudates obtained by the process have qualities and mouthfeel characteristics different from those of the raw material.
