Abstract: [Objective] To reserch and validate on method for rapid detection of sulfur dioxide in food.[Methods] Improved iodometric method and GB method were used as parallel examination of sulfur dioxide in 94 water-solubility foods and 99 non-water-solubility foods.[Results] The coincident rate between the two methods was 91.0% for water-solubility foods, 83.4% for non-water-solubility foods. Difference between the two methods were both nonsignificant.[Conclusion] The improved iodometric method can be used for rapid screening of sulfur dioxide in foods. (文章出处：吴卫平 张 磊 李 洁 彭少杰 赵宇翔 王 华)
