At 48 h p.m., raw meat samples from the LL muscle, cut into 2.5 cm thick slices and placed in an oven bag (a plastic bag used for cooking meat), were heated in water at 80–81 °C until the internal temperature of the meat samples reached 72 °C, and were then subjected to sensory evaluation after cooling to 20 °C. Samples had approximately equal sizes (about 25 g) and were placed in lidded one ounce glass jars labeled with three digit random codes and held in a water bath (54 °C) until presented to the panelists. The analysis was conducted in rooms at daily light and at room temperature (20 °C). To neutralize the taste, each person received hot tea without sugar between the assessments of samples. Sensory evaluation of the LL samples was performed to determine their color, aroma, tenderness, juiciness and flavor. This evaluation was performed in 12 sessions by a team of 4 to 5 trained individuals using a 5-point scale (1 = unacceptable and 5 = very acceptable) according to PN-ISO 4121:1998. At each session, the panelists evaluated 10 randomly presented samples which were served at the same time to each of the panelists. Two sessions were held each day.
