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).
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]
Protein quality is the digestibility and quantity of essential amino acids for providing the proteins in correct ratios for human consumption. There are various methods that rank the quality of different types of protein , some of which are outdated and no longer in use, or not considered as useful as they once were thought to be.
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.

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]
Dehulled hemp seeds (also known as hemp nuts, hemp kernels or hemp hearts) have a protein digestibility corrected amino acid score (PDCAAS) of 0.66, with lysine being the limiting amino acid (digestibility of 92.1%). [3] [10] With its gluten content as low as 4.78 ppm, hemp is attracting attention as a gluten-free (<20 ppm) food material. [4] [9]
