This score means, after digestion of the protein, it provides per unit of protein 100% or more of the indispensable amino acids required. The formula for calculating the PDCAAS percentage is: (mg of limiting amino acid in 1 g of test protein / mg of same amino acid in 1 g of reference protein) x fecal true digestibility percentage. [2]
Digestible Indispensable Amino Acid Score (DIAAS) is a protein quality method proposed in March 2013 by the Food and Agriculture Organization to replace the current protein ranking standard, the Protein Digestibility Corrected Amino Acid Score (PDCAAS).
To calculate the amino acid score the formula used is, the milligram of limiting amino acid in 1 gram of test protein/ the milligram of that same amino acid of reference protein multiplied by 100. [2] If food has a score of 100 it is to considered as a high quality protein with all the necessary nutrients.
The Protein Digestibility Corrected Amino Acid Score (PDCAAS), which was recommended by the Food and Agriculture Organization of the United Nations (FAO), became the industry standard in 1993. FAO has recently recommended the newer Digestible Indispensable Amino Acid Score (DIAAS) to supersede PDCAAS.

Protein digestibility (PD) Protein Digestibility Corrected Amino Acid Score (PDCAAS) Digestible Indispensable Amino Acid Score (DIAAS) These all hold specific advantages and disadvantages over BV, [7] although in the past BV has been held in high regard. [8] [9]
Protein digestibility refers to how well a given protein is digested. [1] Along with the amino acid score, protein digestibility determines the values for PDCAAS and ...
The reduction of water content has the greatest effect of increasing protein as a proportion of the overall mass of the food in question. Not all protein is equally digestible. Protein Digestibility Corrected Amino Acid Score is a method of evaluating the protein quality based on the amino acid requirements of humans. [1]
