2.2. Sample preparation
USDA Choice chuck rolls (square-cut, clod-out; IMPS 116), bottom rounds (IMPS 170), ribeye rolls (lip-on; IMPS 112A), and top sirloins (IMPS 184) were purchased from a local meat processing facility and stored at the NDSU meat science laboratory. It is important to note that the method of sample procurement would mimic the general consumer purchase action of a consumer as the investigators had no information regarding duration of aging, genetic, or environmental background. Chuck rolls were further processed into either a “Delmonico” (chuck eye roll; IMPS 116D) or “Denver” (under blade, center cut; IMPS 116G) steak (Agricultural Marketing Service, 2010). Steaks were cut (2.54 cm thick), vacuumpackaged, and stored at 4 °C before each site presentation. Samples for kabobs were cut into 5.08 × 5.08-cm cubes, vacuum packaged, and stored at 4 °C before each site presentation.
