The Nelson-Somogyi method is one of the classical and widely used methods for the quantitative determination of reducing sugars. PRINCIPLE. The reducing sugars when heated with alkaline copper tartrate reduce the copper from the cupric to cuprous state and thus cuprous oxide is formed.
What is Nelson's test?
The nelson-somogyi method is used to measure reducing sugar by using copper reagents and arsenolmolibdat. … The concentration of sugar in the sample can be determined, the reaction of the forming color can determine the sugar concentration in the sample by measuring the absorbance (Sudarmadji, S. 1984).
