What is Kjeldahl Method for Protein Analysis about?
The document discusses determining the protein content of food samples using the Kjeldahl method. The Kjeldahl method involves several steps: (1) digestion of the sample using sulfuric acid and a catalyst, (2) distillation to convert ammonium sulfate to ammonia gas, (3) collection of the ammonia gas using boric acid, and (4) titration to determine the amount of ammonia collected. The protein content is then calculated indirectly based on the nitrogen content determined by the method.
