摘  要:
为了探讨高密度二氧化碳(DPCD)对牛背最长肌颜色稳定性的影响,将牛肉在25℃,压力分别为7、14、21、28、35MPa处理20min后,测定色泽、肌红蛋白、高铁肌红蛋白还原酶活力(MRA)、琥珀酸脱氢酶活力(SDH)、耗氧率(OCR)的变化。结果表明:DPCD处理后红度a*值、氧合肌红蛋白(OxyMb)含量、MRA、SDH、OCR降低,亮度L*值、高铁肌红蛋白(MetMb)含量升高。在贮藏期间,对照组的各指标变化速度快于处理组,说明DPCD处理可以提高牛肉的颜色稳定性。

摘  要:
In order to study the effect of dense phase carbon dioxide(DPCD) on the color stability of beef,these changes of beef sirloin color,Myoglobin(Mb),Metmyoglobin reducing activity(MRA),succinate dehydrogenase(SDH) activity,oxygen consumption rate(OCR) were investigated after DPCD treatment(25℃,20min,7,14,21,28,35MPa). These results showed that redness a* value,Mb content,OxyMb content,MRA,SDH activity,and OCR decreased and light L* value,MetMb content increased with the increasing pressure. During the period of storage,DPCD treatment could improve the color stability of beef because these values changed more slowly after DPCD treatment than that of the control group.
