ISO 15914:2004规定了用于动物饲料的动物饲料和原料的总淀粉含量的酶测定方法。 该方法也适用于淀粉淀粉的测定。 重要的是，在样品基质中，不存在有助于在340nm测量的消光的组分。 该方法的分析范围为40g/kg至1000g/kg淀粉。标准程序适用范围为200 g/kg〜1000 g/kg。对于较低范围，40g/kg至200g/kg，可以使用标准葡萄糖溶液和样品的另一稀释程序

ISO 15914:2004 specifies a method for the enzymatic determination of the total starch content of animal feeding stuffs and raw materials for animal feeding stuffs. The method is also applicable to the determination of starch in starch. It is important that in the sample matrix no components are present which contribute to the measured extinction at 340 nm. The analytical range of the method is 40 g/kg to 1 000 g/kg starch. The standard procedure is applicable to the range 200 g/kg to 1000 g/kg. For the lower range, 40 g/kg to 200 g/kg, another dilution procedure for the standard glucose solution and samples can be used.
