Abstract:

In order to define the quality characteristics of different anatomical locations of Yunling cattle,the pressing loss rate,cooking loss rate,shear force,pH, L* value,a* value,b* value,crude protein content,crude fat content and moisture of supraspinatus (SU),infraspinatus (IF),triceps brachii (TB),rhomboideus (RH),serratus ventraliscervicis (SVC),splenius (SP),psoas major (PM),longissimus dorsi (LD),latissimus dorsi (LA),semimembranosus (SM),semitendinosus (ST),biceps femoris (BF),gluteus medius (GM),rectusfemoris (RF),vastus lateralis (VL), tensor fasciae latae (TFL) from Yunling cattle carcass were determined.The quality traits of Yunling cattle meat among different anatomical locations were analyzed using variance,correlation and standardization analysis. The result showed that there were significant differences in quality traits among various anatomical locations (P<0.05). The SU,IF,PM,SVC and TFL had higher tenderness comparing to other muscles with shear force values less than 4 kg,while the water holding capacity of SP,ST and VL was poorer than other muscles. The ST had the highest L* value among all muscles. There was significantly positive correlation between shear force and pressing loss, cooking loss rate. The LD and ST had similar quality characteristic,while BF,GM and VL had similar quality characteristic. It was showed that different parts of muscle had significant effect on Yunling cattle meat quality.The quality of forequarter meat was better, which could be used to develop high-end products.

Key words: Yunling cattle; anatomical locations; meat quality; fine segmentation; standardization
