摘　　要：乳制品通常用牛乳或羊乳作为加工原料,通过添加适量维生素、矿物质、碘及其他辅助原料加工而成。国内人口的不断增加,刺激了乳制品的消费市场,乳制品生产厂家也与日俱增。对乳制品进行成分分析鉴定是十分复杂的工作,其成分复杂,增加了碘含量测定的难度。目前用于测定乳制品碘含量的方法有气相色谱法、混合模式色谱柱法与电感耦合等离子体质谱法等,各种方法均有局限性,限制了样品的处理与碘含量的检测。本文重点分析了气相色谱法在乳制品碘含量测定中的应用,通过分析实验过程,对各环节进行总结,以期快速、高效、准确的测定乳制品中的碘含量。Dairy products are usually made from cow’s milk or goat’s milk as the main processing raw materials,adding appropriate amounts of vitamins,minerals,iodine and other auxiliary materials.The continuous increase in the domestic population base has stimulated the consumption of dairy products,and dairy producers are also increasing.Component analysis and identification of dairy products is very complex work,because of its complex composition,increased the difficulty of iodine content determination.At present,gas chromatography,mixed mode column chromatography and inductively coupled plasma mass spectrometry have been used to measure the iodine content in dairy products.Due to the limitations of various methods,the sample treatment and the detection of iodine content are severely restricted.This paper will focus on the application of gas chromatography in the determination of iodine content in dairy products,through the analysis of the experimental process,summarize the various links,in order to be able to quickly,efficiently and accurately determine the iodine content in dairy products.
