标准摘要
[中文适用范围]： 本部分ISO 16634规定了谷物、豆类及磨制谷物产品中总氮含量的测定及粗蛋白质含量的计算方法。该方法（如凯氏法（见参考文献[1]和[6]））不区分蛋白质氮和非蛋白质氮。计算蛋白质含量时使用各种转化系数（见3.2）。 [外文原描述]： ISO 16634-2:2016 specifies a method for the determination of the total nitrogen content and the calculation of the crude protein content of cereals, pulses and milled cereal products. This method, like the Kjeldahl method (see References [1] and [6]), does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of the protein content, various conversion factors are used (see 3.2).
英文名称Food products — Determination of the total nitrogen content by combustion according to the Dumas principle and calculation of the crude protein content — Part 2: Cereals, pulses and milled cereal products
