摘要
调查了广州市常见食物中的硒含量.结果表明:动物性食品内脏、水产品、蛋类和羊肉等食品中的硒含量最为丰富(>150.0μg.kg-1);谷物与豆类中的硒含量相近(46.5～98.3μg.kg-1);蔬菜(15.8μg.kg-1)和水果(4.97μg.kg-1)中硒含量均较低;菌类在植物性食品中的硒含量最高(46.0μg.kg-1).广州市居民硒摄入量为98.5μg.d-1.其中,动物性食品占总硒摄入量的73.7%;植物性食品占26.3%;水产品和猪肉均占22.0%以上;大米占17.2%.广州市食品中的硒含量和居民每日硒摄入量能满足人体生理需要.
The investigation on the food selenium content in Guangzhou City of Guangdong Province showed that viscera of animal foods, aquatic products, eggs, and mutton were abundant with selenium （ 〉 150.0 μg·kg^-1）, followed by cereals and beans （46. 5-98.3μg·kg^-1）, vegetables （15.8 μg·kg^-1）, and fruits （4.97 μg·kg^-1）. Among vegetable foods, mushroom had the highest selenium content （46. 0 μg·kg^-1）. The daily selenium intake of residents in Guangzhou was 98.5 μg, in which, 73.7% was contributed by animal foods, and 26.3% was from vegetable foods. Aquatic products, pork and rice contributed 24. 8%, 22.3% and 17.2%, respectively. The food selenium content and resident daily selenium intake in Guangzhou could meet the demand of human health in the City.
