Define Methods of Determination of Proteins and Amino Acid Content in Foods?
The methods for protein quality evaluation are grouped under the following headings:
I) Analytical methods for the determination of nitrogen and amino acids in foods
II) Chemical and microbiological assays of protein quality
III) Evaluation of protein quality in experimental animals
IV) Clinical methods for evaluation of protein quality
In this section we shall review both the qualitative and quantitative evaluation of protein and amino acid content in foods. We shall begin with the quantitative/analytical method for the determination of nitrogen and amino acid in foods.
