    摘要:

    目的 为提高略阳乌鸡附加值,制备略阳乌鸡低聚肽,并测定其抗氧化活性。方法 以略阳乌鸡肉为原料,利用两种蛋白酶复合酶解,采用响应面法优化略阳乌鸡低聚肽制备工艺,并进行抗氧化活性评价。结果 略阳乌鸡低聚肽双酶复合酶解的最佳制备工艺为采用中性蛋白酶和酸性蛋白酶复合,底物质量浓度3 g/100 mL,酶解时间4 h,酶添加总量9 300 U/g,酶解pH 6.5,酶配比1∶1。该条件下,酶解产物中三氯乙酸(TCA)可溶性短肽含量最高,为10.29 mg/mL,与预测值接近,蛋白回收率为71.52%。略阳乌鸡低聚肽对DPPH自由基、ABTS+自由基、羟自由基的IC50分别为4.675 mg/mL、31.401 μg/mL、4.769 mg/mL,且10 mg/mL略阳乌鸡低聚肽的还原能力接近于0.02 mg/mL的抗坏血酸。结论 试验工艺可以获得较多具有抗氧化活性的略阳乌鸡低聚肽。

    Abstract:

    Objective To prepare oligopeptides from Lueyang black-bone chicken in order to increase its added value and to determine their antioxidant activity.Methods Lueyang black-bone chicken meat was used as the raw material. Two proteases were employed for compound enzymatic hydrolysis, and response surface methodology was applied to optimize the preparation process of Lueyang black-bone chicken oligopeptides and to evaluate their antioxidant activity.Results The optimal preparation process for compound hydrolysis of Lueyang black-bone chicken oligopeptides was as follows: neutral protease and acid protease in combination, substrate concentration 3 g/100 mL, enzymatic hydrolysis time 4 h, total enzyme addition 9 300 U/g, hydrolysis pH 6.5, and enzyme ratio 1∶1. Under these conditions, the hydrolysate had the highest trichloroacetic acid (TCA)-soluble short peptide content of 10.29 mg/mL, which was close to the predicted value, with a protein recovery rate of 71.52%. The IC50 values of Lueyang black-bone chicken oligopeptides for scavenging DPPH radicals, ABTS+ radicals, and hydroxyl radicals were 4.675 mg/mL, 31.401 μg/mL, and 4.769 mg/mL, respectively, and the reducing ability of 10 mg/mL oligopeptides was close to that of ascorbic acid at 0.02 mg/mL.Conclusion The experimental process can yield a considerable amount of Lueyang black-bone chicken oligopeptides with antioxidant activity.
