PDCAAS (Protein Quality)
None
In Vitro
Method Description
This method estimates the Protein Digestibility Corrected Amino Acid Score (PDCAAS) using amino acid composition and in vitro digestibility. Amino acid composition is determined by AOAC 994.12. Protein digestibility is estimated via simulated gastrointestinal digestion, with liberated amino nitrogen quantified spectrophotometrically using a ninhydrin reaction. PDCAAS is calculated as the product of the limiting amino acid score and the measured digestibility.
