摘要：

Quality of bovine longissimus lumborum, infraspinatus and cleidooccipitalis muscles after high-intensity ultrasound (HIU; 40 kHz and a power of 11 W/cm(2) for 0, 40, 60, and 80 min) and aging (0, 7 and 14 d) was evaluated. The effects of HIU on pH and color of meat were not considered negative. HIU improved water holding capacity (WHC) of l.lumborum and infraspinatus only after aging. Whereas, the WHC of cleidooccipitalis increased immediately after sonication. The total collagen of HIU treated samples was significantly lower compared to the untreated samples. Ultrasonication for 80 min was the most effective for infraspinatus and cleidooccipitalis. Toughness decreased with HIU, iii nfraspinatus and l.lumborum tenderized more than cleidooccipitalis. HIU application and 7 d aging is an excellent combined treatment to improve tenderness of the three muscles. Infraspinatus was the most tender meat. HIU could help industry to improve the quality of beef as it helps in tenderization and accelerates maduration particularly of l.lumborum.
