| Abstract: | 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. |
