Open publisher page 4 citations

Abstract

ABSTRACT Occasionally, in the canning of tuna, normal appearing tuna flesh will turn from a desirable white color to an undesirable green color after precooking and prior to retorting. Results demonstrated that the different systems used by the fishermen to hold local albacore tuna prior to delivery to the processor had little influence on the incidence of green discoloration of precooked tuna. Furthermore, frozen storage of local tuna, up to 3 months, did not increase the incidence of green discoloration of precooked tuna.
