摘要
为了降低牛乳中蛋白质质量分数的测量误差,利用自制的仪器,根据光散射原理,通过实验和数据分析,研究了牛乳不同稀释倍率对蛋白质质量分数测量的影响.结果表明,对于大多数的牛乳样品,当其稀释倍率在6.2至7.4范围内时,测量标准偏差达到最小值0.027,满足蛋白质检测国家标准.
In order to decrease the error of measuring concentration of protein in milk, through experiment and data analysis, the effect of milk dilution on measurement of concentration of protein is studied by home-made instrument, according to principles of light scattering. The result shows that measurement standard error reaches minimum 0.027 for most milk sample and satisfies the national criterion of protein detection when dilution ratio ranges from 6.2 to 7.4.
