Pork texture was assessed by two instruments determination(shear method and texture profile analysis,TPA)and also by sensory evaluation on cooked meat.Shear force is significantly(p<0.05)correlated with sensory hardness and juiciness (r=0.73,-0.71,respectively).The hardness of TPA is significantly(p<0.05)correlated with sensory hardness(r=0.81)and the cohesiveness of TPA significantly(p<0.05)correlated with sensory springiness,juiciness, and greasiness(r=-0.79,-0.67, -0.81,respectively).Stepwise regressions between instruments and sensory evaluation are obtained,and the better model belongs to TPA parameters for prediction of sensory characteristics.Also,TPA prediction models are verified.
