Abstract
Abstract This disclosure relates to apparatus and method for the production of fish-paste food products having the appearance of shelled shrimp, crab claws, lobster, abalone, etc. The apparatus comprises a two-piece mold with a mold cavity conforming to the shape of the product, means for spraying a coloring agent into the cavity, filling means for pressing a paste of ground fish meat into the mold cavity, a heating unit for heating and solidifying the fish paste, and means for removing the heated and solidified fish-paste food products from the mold. The invention further comprises the method of providing a split mold having a cavity generally conforming to the shape of a shellfish, spraying the inside wall of the cavity with an aqueous food coloring, filling the cavity with a meat paste under pressure, heating the mold and the paste to a sufficient temperature to cook and color the meat paste, and removing the product from the mold.
