PDCAAS Calculator
Calculate the Protein Digestibility-Corrected Amino Acid Score.
PDCAAS Components
Based on limiting essential amino acid vs reference pattern
Typical: Egg 97%, Meat 92%, Beans 78%
PDCAAS Formula
PDCAAS = (Amino Acid Score x Digestibility) / 100
Maximum value is truncated at 1.0 (100%)
