标准摘要
[中文适用范围]： 本标准规定了采用化学发光法（EPAS）测定巴氏灭菌全脂奶、半脱脂奶、脱脂奶、奶油和调味奶中碱性磷酸酶活性的方法。 本方法适用于奶牛、绵羊、水牛和山羊的奶及奶基饮料。 该方法还适用于任何液体样品，只要稀释后的碱性磷酸酶活性低于每升 7000 毫单位。 注：已对牛、绵羊、水牛和山羊全脂奶以及脱脂牛奶（< 0.5% 脂肪）、20% 脂肪奶油和 2% 脂肪巧克力奶（所有质量分数）进行了成功的合作试验。 [外文原描述]： ISO 22160|IDF 209:2007 specifies a method for the determination of the alkaline phosphatase activity in pasteurized whole milk, semi-skimmed milk, skimmed milk, cream and flavoured milks using a chemiluminescent (EPAS) method. The method is applicable to milk and milk-based drinks from cows, sheep, buffalo and goats. The method is also suitable for any liquid-based sample if diluted in such a way that the diluted alkaline phosphatase activity has less than 7 000 milliunits per litre.
