Chum salmon flesh color is the most important factor in respect of quality. The present flesh color evaluation is discriminated with the subjective method. However, in order to be anxious about the incorrect discrimination by a judgment person's individual variation, it is desirable to evaluate flesh color by the objective method. It becomes important to set up the valuation basis reliable for that purpose. When a salmon processor actually discriminates flesh color grades in a disposal plant, the discrimination standard of the high accuracy adapted to visual evaluation of a fillet color is needed. Therefore, in this study, it was investigated how the difference in the form of a chum salmon sample would affect color measurement values. Based on the result, we made the objective valuation basis corresponding to subjective evaluation from CIELAB color system values in a fillet, and established the discrimination standard for chum salmon flesh color.
