Protein Quality - References

A report published in 1991 by the Food and Agricultural Organization/World Health Organization (FAO/WHO)* recommended a more acceptable and validated procedure for protein quality evaluation: the Protein Digestibility-Corrected Amino Acid Score (PDCAAS). The PDCAAS method is based on a food protein's amino acid content, digestibility and ability to supply essential amino acids in the amounts adequate to meet human needs. Using this method, Solae brand isolated soy proteins have the highest obtainable score (1.0) for calculating the corrected protein value. No protein can have a PDCAAS greater than 1.0.
