ABSTRACT:
The rate of color development in fish flesh is dramatically accelerated by injecting the fish flesh with a first aqueous solution of the dye, lecithin with which to emulsify the fatty oils of the fish flesh, and a food grade salt; and then ageing the injected fish flesh by soaking it in a second solution of the dye and the salt, with the salt being dissolved in the second solution in such a lower concentration, relative to the concentration of the salt in the first solution, to generate an osmotic pressure differential between the respective first and second solutions, which will diffuse the dye throughout the flesh and produce a substantially even hue therethroughout in about 20-28 hours.
