Method Reference:
US Patent Application No. 14/599,050: Method for Estimating In Vivo Protein Digestibility, Plank, DW.
Method Description:
Initially, a sample is measured for the Amino Acid composition using method AOAC 994.12. A human digestion simulation follows, breaking down the proteins into amino acids, which are reacted with Ninhydrin and measured; determining the digestibility. Taking the limiting amino acid value the digestibility is corrected resulting in a Protein Digestibility Corrected Amino Acid Score (PDCAAS).
Additional Information:
The following values are reported:
- Full amino acid profile
- First limiting amino acid
- Sample moisture
- Total protein (both by AAA and combustion nitrogen)
- Animal safe digestibility
- Amino acid score
