By using the high performance liquid chromatography (including UV detector), chromatogram conditions of emerging peak and pretreatment methods of moon-cake, cake , dry soybean curd ,sausage and noodle etc had been studied in this paper. At the same time, sodium diacetate can be determined, and its qualitative and quantitative tests in this method have been done. The experimental results show that linear relation of this method is preferable .recovery of this method was more than 90%; RSD <3.0%, precision of this method is high and the least detecting concentration of this method is 0.03g/kg, the least guantitative detecte limit of this method is 0.10g/kg.
