2.10. Instrumental color measurement
Color was determined at 3 defined areas on the cut surface of each sample using a Minolta Chroma Meter CR-400 (Minolta Camera Co., Ltd., Osaka, Japan) that was standardized with a white plate (Y ¼ 86.3, X ¼ 0.3165 and y ¼ 0.3242). Special care was taken to avoid scanning areas of fat in the sample. Color was expressed according to the Commission International de l’Eclairage (CIE) system and reported as CIE L* (lightness), CIE a* (redness), CIE b* (yellowness).
