據歐盟網站消息，5月6日歐盟發(fā)布（EU）2015/723號法規(guī)，批準維生素H作為動物飼料添加劑。該法規(guī)自公布二十日起生效。

生物素在添加劑分類當中屬于“營養(yǎng)添加劑”，在功能分組當中屬于“維生素、維生素原以及有類似效應化學性質定義良好物質”，被批準作為動物營養(yǎng)添加劑。

維生素H的測定方法如下：

飼料添加劑中D-（+）-維生素H的測定：電位滴定法測定和光學旋轉測定（歐盟藥典6.0方法01/2008:1073）；預混合物和飼料中D-（+）-維生素H的測定：反相高效液相色譜法結合質譜法（RP-HPLC-MS/MS）；水中D-（+）-維生素H的測定：微生物測定法（美國法典21，方法（88） 1986）。
