Abstract
A method for color development of a crustacean in a fresh state, comprising the steps of: treating a crustacean such as a lobster or a crab, in which a shell thereof is left as it is or removed, with an alkaline aqueous solution having a pH value in a range of from 10 to 14 to thereby develop the red color of a carotenoid pigment; and the treating the crustacean with an aqueous solution of an edible acid, such as an acetic acid, to thereby perform neutralization.

A method for color development of a crustacean, in a fresh state, comprising the steps of:
- treating a crustacean, optionally with its shell, with an aqueous alkaline solution having a pH of from 10 to 14 to thereby develop a red color of a carotenoid pigment in the crustacean;
- and then treating said crustacean with an aqueous solution of an edible acid for a sufficient time to develop a weakly alkaline pH of 7.5 to 10 in the surface of said crustacean.
A red color-developed crustacean in a fresh state, which is color-developed through treatment of the crustacean, optionally having a shell, with an aqueous alkaline solution having a pH of from 10 to 14 to thereby develop the red color of a carotenoid pigment in the crustacean, which crustacean is then treated with an aqueous solution of an edible acid to develop in the surface of a of said crustacean a weakly alkaline pH of 7.5 to 10.
