Abstract：Changes in the texture characteristics of meat from yaks in the south of Gansu province during postmortem aging
at 4 ℃ were evaluated using texture profile analysis (TPA). Meanwhile, their correlations were also analyzed. During 7 days of
postmortem aging, all the texture characteristics of hardness, springiness, chewiness adhesiveness and cohesiveness showed an overall
downward trend. A significant positive correlation between hardness and chewiness or cohesiveness was observed (P ＜ 0.01). In
addition, yak meat chewiness also indicated a significant positive correlation with hardness or cohesiveness (P ＜ 0.01).
