Shrimps treated with lysine and arginine showed reddish color after thawing. However, the treatment with arginine at 1.0 g/100 ml could increase cooking yield of shrimp from 75.02 (control) to 97.59 g/100 g fresh shrimp comparable to 101.36 g/100 g fresh shrimp with STPP treatment and obtained higher sensory acceptability.
