Abstract
Method for processing Euphausia superba, a large-sized animal plankton of 15-50mm body length which is quite similar to the small shrimp, Sergestes lucens, in dimension, shape and taste. This method basically comprises applying, to a mass of fresh bodies of Euphausia superba, an appropriate force whereby from the head-chest portion of each body there may be readily expelled the internal organs, above all the liver of objectionable taste, leaving the desired meat of the tail-belly portion within the shell then subjecting the mass of the bodies of Euphausia superba so treated to the steps of heating in hot or boiling water to effect protein thermal coagulation in most of the proteins of the meat portion, removing the juices produced in a gap formed between the shell and the thermally shrunken meat portion, freezing quickly each separate body, without adherence to one another, to a temperature of about -35.degree. C, and subjecting the mass to pellet shooting and crushing, whereby the frozen and brittle shell, gill portion, eyes, feelers and legs of the plankton are distintegrated and made readily removable from the undamaged meat portion to isolate selectively a mass of the meat port…
