摘要
建立了一种用高效液相色谱法测定奶粉中酪蛋白磷酸肽(CPP)含量的方法。结果表明:该法前处理简便,专一性好,灵敏度高,检出限为10μg/mL。在10~200μg/mL范围内线性回归方程为y=0.1113x+0.2131,R2=0.9994,回收率为95% ̄105%,可用于测定奶粉中CPP的含量。
A specific method was developed to determine the Casein Phosphopeptides (CPPs) in milk powder. The method was proved to be simple, specific and sensitive. The detection limit was 10 μg/mL. Within the concentration range of 10-200 μg/mL, the linear regression equation was y = 0.1113x + 0.2131, R^2= 0.9994. The recovery ranges from 95% to 105%. Thus, this method can be applied to the determination of CPP in milk powder.
