Kjeldahl Method an overview | ScienceDirect Topics
The longtime standard for protein analysis has been the Kjeldahl method (AOAC Method 97605) The longevity of this method is obvious when considering that the method was first published in 1883 In the past, the need to develop faster methods for protein analyses has probably not been perceived to be as important as the need for rapid fat and moistureThe nitrogen/protein analysis according to Kjeldahl is up to date still the reference method in analytics With its high degree of versatility, the method is suitable for many applications, eg food analysis, feed analysis, soil or water analysis In addition to the versatility, the very high precision also speaks for the method Particularly in case of highly inhomogeneous sampleKjeldahl analysis for nitrogen and protein
PROTEIN DETERMINATION BY KJELDAHL METHOD
PROTEIN DETERMINATION BY KJELDAHL METHOD LIM PY INTRODUCTION In the presence of sulphuric acid and catalyst, the nitrogen atom in the nitrogenous organic compound is converted to ammonium sulphate The ammonia is then distilled from an alkaline medium and absorbed in boric acid The ammonia is then determined by titration with a standard mineralThis method is also used for estimating the protein content in food Kjeldahl method is an analytical chemistry method that helps in the quantitative measurement and determination of nitrogen present in organic substances as well as inorganic compounds The method was first developed by Johan Kjeldahl in the year 1883 This process plays an important role in theKjeldahl Method Principle, Reaction, Formula
