PRODUCTION OF PROCESSED EGG PRODUCT

PROBLEM TO BE SOLVED: To produce a processed egg product capable of eliminating sulfurization blackening and greening, having a bright color tone and retaining a soft texture and suitable as a raw material, etc. for egg salads by keeping a heat coagulated egg in an atmosphere enriched with oxygen. SOLUTION: A heat coagulated egg is filled in an oxygen-permeable container and intactly kept in an atmosphere enriched with oxygen (in preferably >=30% oxygen concentration) to produce a processed egg product. Otherwise, the heat coagulated egg is preferably intactly filled in an oxygen-impermeable container or together with a solution filled therein and the interior of the container is then preferably replaced with an atmosphere enriched with the oxygen (at preferably >=15 mg/L dissolved oxygen concentration) and hermetically sealed to store the heat coagulated egg. The heat coagulated egg is preferably kept in an atmosphere of air under >=1.2 kg.f/cm pressure.
