摘要目的 调查我国6个省份食品中含碘量,补充食品含碘量数据库,为我国不同地区科学补碘提供依据.方法 采集福建、重庆、山东、安徽、甘肃、吉林6个省份的地产常用食品,共8类39种.将谷物、豆类及干燥样品粉碎成粉末；新鲜果蔬类样品洗净,烘干至恒重,粉碎成粉末；禽、畜肉及水产类样品洗净,取其可食用部分制成肉糜,烘干至恒重,粉碎成粉末.采用碱灰化-砷铈催化分光光度法,波长为405 nm,测定上述食品中含碘量.使用SPSS 13.0统计软件进行数据处理及分析,各类食品的总含碘量测定结果以中位数(P50)和四分位数间距(P25和P25)表示.结果 福建、重庆、山东、安徽、甘肃、吉林6个省份,谷物豆类含碘量分别为11.9、12.0、48.0、95.1、13.0、3.1 μg/kg;薯类含碘量分别53.9、26.3、74.9、43.7、76.8、38 μg/kg;肉蛋类含碘量分别为56.0、30.4、78.6、124.6、47.7、34.8 μg/kg；水产类含碘量分别为319.3、144.7、186.6、241.3、155.4、213.3 μg/kg;蔬菜类含碘量分别为166.6、145.1、131.7、218.0、205.4、98.1 μg/kg;水果类含碘量分别为105.5、17.8、80.9、1.7、76.7、10.3 μg/kg;海带紫菜类含碘量分别为36.0×103、1292.0×103、2810.0 × 103、48.0×103、75.0×103、120.0×103 μg/kg;咸菜酱类含碘量分别为640.4、4163.5、3073.7、2635.3、1540.9、492.0μg/kg.结论 不同种类食品的含碘量不同,不同省份相同种类的食品含碘量也不同,本研究结果是对2004中国食品成分表数据库的补充.

abstractsObjective To investigate the iodine content of food in six provinces of China,to add the results of this survey to the food iodine content database,and to provide a scientific basis for iodine supplementation in different parts of China.Methods A total of 8 categories and 39 species common food produced locally in the six provinces of Fujian,Chongqing,Shandong,Anhui,Gansu and Jilin were collected.Samples of cereals,beans and other dry samples were crushed into powder; samples of fresh fruits and vegetables were washed and dried to constant weight,and crushed into powder; poultry,meat and fish samples were washed and then their edible parts were crushed into meat paste,bake dried to constant weight,and crushed into powder.Iodine content in the above-mentioned food was determined by catalytic spectrophotometry,and the wavelength was 405 nm.Data processing and statistical analysis were carried out by using SPSS 13.0 statistical software.The results of total iodine content of the various types of food were expressed as median(P50) and interquartile range(P25 and P75).Results The iodine content of the cereal in Fujian,Chongqing,Shandong,Anhui,Gansu and Jilin were 11.9,12.0,48.0,95.1,13.0and 3.1 μg/kg,respectively; of the potato were 53.9,26.3,74.9,43.7,76.8 and 38.5 μg/kg,respectively; of the meat and the eggs were 56.0,30.4,78.6,124.6,47.7 and 34.8 μg/kg,respectively; of the aquatic products were 319.3,144.7,186.6,241.3,155.4 and 213.3 μg/kg,respectively; of the vegetables were 166.6,145.1,131.7,218.0,205.4 and 98.1 μg/kg,respectively; of the fruits were 105.5,17.8,80.9,1.7,76.7 and 10.3 μg/kg,respectively; of the kelp and laver were 36.0 × 103,1292.0 × 103,2810.0 × 103,48.0 × 103,75.0 × 103 and 120.0 × 103 μg/kg,respectively; of the Chinese pickled vegetables were 640.4,4163.5,3073.7,2635.3,1540.9 and 492.0 μg/kg,respectively.Conclusions The iodine content of different types of food,and same kind of food from different provinces are different.The results are a complement to the 2004 Chinese food composition database.
