  • Title: Comparison of modified automatic Dumas method and the traditional Kjeldahl method for nitrogen determination in infant food.
    Author: Bellomonte G, Costantini A, Giammarioli S.
    Journal: J Assoc Off Anal Chem; 1987; 70(2):227-9. PubMed ID: 3571115.
    Abstract:
    This study compares 2 methods for determining nitrogen and protein in various types of infant food: the Kjeldahl method, developed in 1883, which is time consuming and labor intensive, and a newer, automatic method, based on the Dumas method. In each category of infant food considered, the results obtained from both methods are shown to be comparable; however, the modified Dumas method is quicker, easier, and does not pollute the laboratory environment.
