| Popis: | The objectives of this research was to formulate the relationships between muscle glycolytic potential (an estimator of glycogen level) at time of slaughter and ultimate pH in various porcine, bovine and ovine muscles. Samples were taken from different muscles i.e., in pigs: M. semimembranosus and M. semispinalis capitis; in calves: M. longissimus thoracis et lumborum, M. psoas major and M. rectus abdominis, and in sheep: M. semitendinosus, M. supraspinatus, M. pectoralis profundus and M. rectus abdominis. Three regression models were tested, i.e., linear, linear segmented model with plateau, and quadratic segmented model with plateau. The quadratic model with plateau gave the highest correlation coefficients in both muscles of pigs, the three muscles of calves and M. semitendinosus and M. pectoralis profundus of sheep. It can be concluded that, in most muscles, ultimate pH decreases following a curvilinear regression when glycolytic potential increases, until a plateau value dependent on the animal species and muscle. The glycolytic potential corresponding to the convergence point between the quadratic part of the curve and the plateau depends also on muscle and animal species. |
