Micro Kjeldahl Distillation Method Percentage of Crude Protein = (Blank-Titre Value) x 1.401 x 6.25 x 20 x Normality of NaOH / Sample Weight )


Calculate the percentage of crude protein in the food based on the blank titre value of 50, titre value of 30, normality of NaOH of 20N and sample weight 50.


Percentage of Crude Protein = (50) x 1.401 x 6.25 x 20 x 20 / 50 )
= 1401
