Method Reference:
US Pat Appl 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
