  • Process for bleaching dark fish meat
    Patent number: 4136204
    Abstract: A process for bleaching dark fish meat such as skeletal cod threshings. The fish is bleached in the undissolved state at ambient temperature with a dilute aqueous solution of hydrogen peroxide at a pH of 10.5 to 11.5. Residual hydrogen peroxide is subsequently removed from the separated bleached fish by, for example, treatment with an aqueous solution of catalase at a pH of 7.5 to 8.0. The pH of the fish is finally adjusted to a value of from 6 to 7, that is, the pH of natural fish, by washing it with an aqueous solution of a food acid, for example, citric acid.
