Crude Protein Analysis by Kjeldahl Method by Husna Atiqah is a document available to read on EtoBox.

This experiment aimed to determine the crude protein content in a food sample using the Kjeldahl method. The method involved three main steps: digestion, distillation, and titration. In digestion, the food sample was weighed and digested with acid and catalyst. Distillation released ammonia gas which was collected in an acid solution. Titration then determined the ammonia content which was used to calculate the percentage of nitrogen and crude protein in the sample. The results showed crude protein percenta
