ABSTRACT:
A process is described for extraction and recovery of chemicals from the shell of various crustacea species. Significant features of the process are determination and use of conditions for extraction which are sufficient to liberate protein from its combination with chitin in the shell matrix and to dissolve it as an alkali proteinate solution while causing minimum alteration to the protein so that products of high nutritional quality can be obtained; the conditions for the extraction of the chitin from the shell matrix and in a useful form; and, the recovery of a calcium compound from the shell matrix.
