摘要
为了建立一种快速准确检测乳与乳制品中甲醛含量的方法，本文采用沉淀蛋白的方法，然后对处理样品利用2，4-二硝基苯肼对甲醛进行衍生，通过液相色谱仪检测，回收率在90．64～108．41％之间，均能满足仪器法检测乳与乳制品甲醛含黾的要求。
The article establishes a fast and accurate method to determine the formaldehyde content in milk and diary products. After precipitation the protein, the samples were contents were measured by HPLC. The method is meet the demand to determine recovery of each sample formaldehyde content in derived with 2,4-Dinitrophenylhydrazine, and its is between 90.64% and 108.41%, shows that the milk and diary products.
