Nitrogen and protein determination in milk powder (Kjeldahl)
通过比色滴定根据Kjeldahl方法乳粉中的氮气和蛋白质测定
In this note a reliable and efficient method for the determination of total nitrogen and protein in milk powder, according to EN ISO 8968-1:2014 [1], AOAC 991.20 [2] and AOAC 930.29 [3] is presented. The samples are digested using the KjelDigester K-449. The distillation and boric acid titration are performed with the KjelMaster K-375 by colorimetric titration and the KjelSampler K-376.
