【摘要】 通过对不同种类的肉及肉制品中磷酸盐的分析研究,对钼蓝分光光度法测定食品中复合磷酸盐进行改进。方法采用钼蓝比色法与GB/T5009.87—2003钼蓝分光光度法测定食品中复合磷酸盐的方法进行比对。改进后,其标准系列线性良好,相关系数r=0.9998,回归方程C=0.02124A-0.004333,该法简化了操作过程,显色明显,得到了较好的精密度和准确度。更多还原

【Abstract】 After researching in the phosphates in different kinds of meat and meat products,we improve Moblue spectrophotometric method of compound phosphate in food.The method uses Moblue spectrophotometric with GB/T5009.87-2003 determination of food in the compound phosphate method carries on rightly compared to.After the improvement, its standard series linearity isbetter ,the correlation coefficient r =0.9998, the regression equation C=0.02124A-0.004333, and the detection limit of 0.034 mg/L.This method simplified the operating process, the color clear, obtained a better precision and accuracy.更多还原
