N/Protein Determination in Cereals According to the Kjeldahl Method

30 May 2017

Cereals contain between 8-15% of different kinds of proteins such as albumins, globulins, prolamines, gliadins, glutelins and glutenins. Their chemical composition is important not only for nutritional purpose, but also for the bread dough and its process of baking. This application note presents a method for nitrogen and protein determination in cereals according to the Kjeldahl method.

DKL Series and DK Series - Kjeldahl Digesters

Velp Scientifica

DK Series digesters are traditional digesters, consisting of an aluminum heating block to offer high thermal homogeneity. The DKL Series of digesters offers a premium level of automation: lowering and lifting of the samples take place automatically, as well as the separation between the test tubes and the suction cup. VELP digesters work in accordance with a variety of Standards (such as AOAC, ISO, EPA, DIN etc.)
