Abstract:
An ion chromatography (IC) method for the determination of phosphate compound in frozen prepared food was developed in this paper. The sample was extracted by water used ultrasonic wave washer. After protein and fat precipitation by zinc acetate and potassium ferrocyanide, the sample was analyzed by IC using conductivity detector. The RSD, precision and standard recovery of the method were >0.9990, <2% and 84.7~96.3%, respectively.
