Protein Digestibility Corrected Amino Acid Score information
Method of evaluating a protein's quality
Protein digestibility-corrected amino acid score (PDCAAS) is a method of evaluating the quality of a protein based on both the amino acid requirements of humans and their ability to digest it.
The PDCAAS rating was adopted by the US FDA and the Food and Agriculture Organization of the United Nations/World Health Organization (FAO/WHO) in 1993 as "the preferred 'best'" method to determine protein quality.[1]
In 2013, FAO proposed changing to Digestible Indispensable Amino Acid Score.
