Tenderness and sensory evaluation
48 hours post mortem, the raw meat samples (about 200 g) in a plastic
bag were heated in water at 80–81 °C until reaching an internal temperature of 72 °C inside the meat samples, and then subjected to
tenderness and sensory evaluation. Sensory evaluation of the loin
sample was performed to determine its colour, aroma, tenderness,
juiciness and flavour. The evaluation was performed by a trained 4 to
5 person team in a 5-point scale (1 = unacceptable and 5 = very acceptable).
Tenderness was measured using the Warner-Bratzler apparatus
(WB) manufactured at the Baking Industry Research Centre in Bydgoszcz
(Poland)
