本欧洲标准描述了在压力消解后使用电感耦合等离子体（ICP-OES）的光发射光谱法测定食品中的矿物质和微量元素的方法。 这种方法已经在根据ISO 5725 [1]关于儿童食品大豆，奶酪，鸡肉，小麦粉，苹果汁，龙虾和牛奶，钙含量为70mg/kg至7178mg/kg的实验室间研究中得到验证，铜从0.60 mg/kg至16,40 mg/kg，铁含量为0.088 mg/kg至77 mg/kg，钾含量为605 mg/kg至14 312 mg/kg，镁从45mg/kg到1,174mg/kg，锰范围为0.444mg/kg至5,12mg/kg，钠范围为11mg/kg至2 220mg/kg，磷范围从72 mg/kg到9 708 mg/kg，硫含量为26 mg/kg至8 542 mg/kg，锌含量为0.16 mg/kg至43 mg/kg

This European Standard describes a method for the determination of minerals and trace elements in foodstuffs using optical emission spectrometry with inductively coupled plasma (ICP-OES) after pressure digestion. This method has been validated in an interlaboratory study according to ISO 5725 [1] on children's food soya, cheese, chicken meat, wheat flour, apple juice, lobster and milk, with calcium ranging from 70 mg/kg to 7178 mg/kg, with copper ranging from 0,60 mg/kg to 16,40 mg/kg, with iron ranging from 0,88 mg/kg to 77 mg/kg, with potassium ranging from 605 mg/kg to 14 312 mg/kg, with magnesium ranging from 45 mg/kg to 1 174 mg/kg, with manganese ranging from 0,44 mg/kg to 5,12 mg/kg, with sodium ranging from 11 mg/kg to 2 220 mg/kg, with phosphorus ranging from 72 mg/kg to 9 708 mg/kg, with sulfur ranging from 26 mg/kg to 8 542 mg/kg and with zinc ranging from 0,16 mg/kg to 43,5 mg/kg.
