Marbling scores range from 1 (devoid) to 9 (abundant).
Color scores range from 1 (pale pinkish gray to white) to 6 (dark purplish red).
Firmness scores range from 1 (very soft) to 5 (very firm).
All quality characteristics (firmness, color, and marbling) were measured subjectively bythe same three trained personnel from above using techniques specified in the NPPC Composition and Quality Assessment Procedures (NPPC 2000).
Statistical Analysis. Analysis was conducted by using the Statistical Analysis System. All data were analyzed linearly using the GLM procedure of SAS (Cary, NC) (Barr and Goodnight 1972). A P value of 0.05 was considered significant. Model terms included effect of three treatments: 0 ppm RAC, 5 ppm RAC, and 10 ppm RAC.
