Abstract
Abstract A fish bait and method of production thereof wherein a nonhomogeneous body having a toughened exterior skin-like structure surrounding a gelatinous body is formed by mixing a gel-forming proteinaceous material and water at a temperature above the solgel transition temperature, forming the proteinaceous mass into the desired shape, cooling the shaped mass and treating the exterior surface of the shaped mass with a tanning agent such as formaldehyde, resulting in a relatively insoluble skin surrounding a relatively soluble gel structure. Humectants may be added to alter the gel characteristics and fish egg waste material and other cannery wastes may be utilized as part or all of the proteinaceous material to provide the characteristic odor associated with salmon eggs.
