This article would be throwing light on Protein Estimation By Kjeldahl Method. Principle Of Kjeldahl Method Johan Kjeldahl first introduced the Kjeldahl method in 1883 at a meeting of the Danish Chemical Society. Johan Kjeldahl, at that time Carlsberg laboratory manager, was assigned to scientifically observe the processes involved in beer production. by means of the Kjeldahl Method The Kjeldahl method is used to determine the nitrogen content in organic and inorganic samples.

The Kjeldahl method or Kjeldahl digestion (Danish pronunciation: [ˈkʰelˌtɛˀl]) in analytical chemistry is a method for the quantitative determination of nitrogen contained in organic substances plus the nitrogen contained in the inorganic compounds ammonia and ammonium (NH 3 /NH 4 +).

Our KjelROC range of automatic Kjeldahl analyzers offers innovative, precise and cost efficient solutions for Distillation, Titration and determination of protein according to the Kjeldahl method. The Kjeldahl method was developed in 1883 by a brewer called Johann Kjeldahl. A food is digested with a strong acid so that it releases nitrogen which can be determined by a suitable titration technique. The amount of protein present is then calculated from the nitrogen concentration of the food.
