The invention discloses a determination method of iodine content in food and application thereof, the determination method comprises the following steps: taking a sample to be determined, adding an ammonium carbonate solution, and uniformly dispersing to obtain a dispersion liquid; the dispersion liquid is placed in a constant-temperature drying box at the temperature of 80-105 DEG C for extraction, supernatant liquid is taken and filtered, and then a to-be-detected sample solution is obtained; and testing the concentration of iodine in the to-be-tested sample solution. The method for determining the iodine content in the food can accurately and rapidly determine the iodine content in the food, has the characteristics of accurate detection and good recovery rate, also has the advantages of convenience and low cost, and is suitable for determining the total iodine content in different foods. 本发明公开了一种食品中碘含量的测定方法及其应用，该测定方法包括如下步骤：取待测样品，加入碳酸铵溶液，分散均匀得分散液；将分散液置于温度为80℃～105℃的恒温干燥箱进行提取，取上层清液过滤后即得待测样品溶液；测试待测样品溶液中碘的浓度。该食
