PROCESS FOR PRODUCING PROTEINOUS MATERIAL

摘要

A process is provided herein for producing a proteinous material. The process comprises the first step of coarsely grinding fish bodies including bones and/or shells, from which the internals had been removed optionally together with heads and/or skins. Then three alterantive further steps may be carried out, namely (1) fermenting the coarsely ground fish bodies with an enzyme and/or a microorganism, inactivating the enzyme and/or microorganism, and then finely grinding the fermented material to give a particle size of bones and/or shells of 100.mu. or less; or (2) finely grinding the coarsely ground fish bodies to give a particle size of bones and/or shells of 100.mu. or less, fermenting the same with an enzyme and/or a microorganism, and then inactivating the enzyme and/or the microorganism; or (3) finely grinding the coarsely ground fish bodies to give a particle size of bones and/or shells of 100.mu. or less while fermenting the same with an enzyme and/or a microorganism and then inactivating the enzyme and/or the microorganism.
