Abstract
Residual bleaching agent is removed from bleached fish without excessive take-up of washing water by contacting with an aqueous solution of alkali metal bicarbonate or carbonate, preferably a solution of sodium or potassium bicarbonate. The weight ratio of fish to liquor normally employed is in the range of 1:2.5 to 1:30 and frequently 1:3 to 1:10. The concentration of the solution normally employed is in the range of 0.05 to 0.15 moles per litre and the temperature of the solution normally falls in the range of 0 to 30 DEG C and frequently at ambient temperature +/-5 DEG C. The fish flesh is finally washed with a dilute catalase solution and its pH is thereafter adjusted to within the range of pH 6.0 to 6.5. The process is particularly applicable to H2O2 bleaching processes.
