Goals:

Protein Determination: Learn how to determine the crude protein content in food samples using the Kjeldahl method.
Theoretical Understanding: Understand the concepts that involve the analysis of proteins and their importance in biological processes and nutrition.
Practical Skills: Develop essential laboratory skills for the chemical analysis of foods.
Practical Applications:

Understanding the function of proteins in the body is essential, as they control almost all cellular processes and perform a variety of organic functions. These concepts are crucial for anyone seeking to understand the molecular mechanisms of biological processes.

Security:

To ensure safety during the experiment, wear a lab coat, gloves and protective glasses. These PPE are essential to avoid direct contact with the reagents used in protein determination. Reagents must be handled in the fume hood to ensure safety.

Laboratory Scenario:

The experiment will be conducted on the bench. The burette, Erlenmeyer flask, claws, pissette, pipettor, universal support, micro-Kjeldahl digestion tubes, filter paper and thermal insulating protective gloves are in the lower cabinet of the bench. The reagents including boric acid P.A., sulfuric acid P.A., hydrochloric acid P.A., ethyl alcohol P.A., sodium selenite P.A., copper sulfate P.A., sodium sulfate P.A., 0.1N hydrochloric acid solution, sodium hydroxide solution (40%), bromocresol green and methyl red P.A. will be on the bench together with the calorimeter.
