摘要
以鹿血为原料,采用超声波破碎法制备血红蛋白粉,然后对其进行酶解制备鹿血生物活性肽。在筛选出最适蛋白酶的基础上,以DPPH自由基的清除率为指标,通过单因素试验结合响应面法优化鹿血生物活性肽的酶解法制备工艺。结果表明:最适蛋白酶为木瓜蛋白酶;最佳制备工艺为酶解温度58℃、酶解时间4 h、酶添加量7.3%(以血红蛋白粉质量计)、pH 10.2,在此条件下,鹿血生物活性肽对DPPH自由基的清除率最大,为75.96%。
Using deer blood as raw material,the hemoglobin powder was prepared by ultrasonic crushing method,and then the deer blood bioactive peptide was prepared by enzymolysis.On the basis of selecting the most suitable protease,taking DPPH free radical clearance rate as index,the enzymatic preparation process of deer blood bioactive peptide was optimized by single factor test and response surface method.The results showed that the most suitable protease was papain.The optimal preparation process was enzy-matic hydrolysis temperature 58℃,enzymatic hydrolysistime4h,enzymeadditionamount7.3%(based on the mass of hemoglobin powder),pH 10.2.Under these conditions,the deer blood bioactive peptide had the highest clearance rate of DPPH free radicals,which was 75.96%.
