PREVENTING THE APPEARANCE OF MELANOSIS IN SHELLFISH

摘要

A process and apparatus for preventing melanosis in shellfish which are to be preserved for freezing are disclosed in which shellfish in a container are covered with an aqueous solution of an innocuous acid, such as citric acid, and the interior of the container is pressurized with carbon dioxide at a predetermined pressure and for a predetermined time. As a result, carbonic anhydride and citric acid penetrate the bodies of the shellfish to preserve the fish and prevent melanosis.
