摘要: 选用鼠尾草酸质量分数分别为5%和20%的迷迭香(CAP05、CAP20),分别以一定质量浓度梯度喷射到生鲜猪肉表面,并将猪肉置于超市标准荧光灯下冷藏8d。检测迷迭香对猪肉贮藏期间CIE a*值、色相、氧合肌红蛋白、正铁肌红蛋白、TBARS值、蛋白质羰基和感官评价的影响。实验发现,5%鼠尾草酸的抗氧化效果总体优于20%鼠尾草酸的作用效果,其中r500、r1000和R500组较大程度上延缓了肉品的变色及脂肪和蛋白质的氧化,且r500组肉品在第8天变色最轻、异味最少。统计分析发现猪肉的氧合肌红蛋白、正铁肌红蛋白、TBARS值和蛋白质羰基与颜色CIE a*值之间具有极显著的相关性(P<0.01)。

Abstract: Two rosemary extracts with different carnosic acid contents (CAP05 and CAP20) were added to fresh pork. Samples were stored at 4 ℃ with illumination of standard supermarket fluorescent lamps for 8 days. CIE a* value, hue, oxymyoglobin, metmyoglobin, lipid and protein oxidation and sensory evaluation of fresh pork were investigated. Results showed that rosemary with 5% carnosic acid revealed better protective effect on fresh pork than rosemary with 20% carnosic acid. Moreover, r500, r1000 and R500 exhibited better protection against discoloration, lipid and protein oxidation during storage. The r500 had the least discoloration and odor at the end of storage. Statistical analysis showed a significant correlation of color CIE a* value with the contents of oxymyoglobin, metmyoglobin, TBARS and carbonyls (P<0.01).
