摘要: 为了研究氧化对禽类肌肉的影响程度,为鸡肉品质调控的研究提供参考,本实验以白羽肉鸡为研究对象,选取鸡的胸、腿肉,测定氧化对肌肉持水性能、营养素含量以及对胸肉钙蛋白酶活力的影响。结果显示:氧化可造成肉鸡胸肉和腿肉持水力下降,蒸煮损失率增加,产品得率降低;且过氧化氢(H2O2)溶液浓度对蛋白氧化程度和脂肪氧化程度有影响,随着H2O2溶液浓度的增大,肌肉蛋白质和脂质等营养素水平呈显著下降趋势。而在氧化对钙蛋白酶的活性研究中发现钙蛋白酶活力随H2O2浓度增大而降低,从而推测钙蛋白酶活力水平变化与白羽肉鸡肉质改变的关系密切。

Abstract: This study explored the effect of oxidation treatment on the water-holding capacity, nutrient contents and calpain activity of breast and drumstick meat from white feather broilers. The results showed that oxidation treatment could decrease the water-holding capacity, increase the cooking loss and consequently reduce the cooking yield of chicken breast and drumstick meat. The concentration of hydrogen peroxide solution (H2O2) affected protein and lipid oxidation. The levels of nutrients such as protein and lipid significantly dropped with increasing concentration of H2O2. Similarly, calpain activity declined with the increase in H2O2 concentration. Thus, it is speculated that changes in calpain activity are closely associated with changes in broiler meat quality.

Key words: oxidation, water-holding capacity, eating quality, calpain, white feather broiler
