This new option allows you to adjust calculated protein Daily Value using the PDCAAS (protein digestibility–corrected amino acid score).
Use ONLY if you understand what this means, otherwise leave it set at 1. Different types of protein can have different values.
USED FOR PROTEIN LISTED WITH A Daily Value amount ONLY.
Example: set PDCAAS to 0.82 for pea protein. The %DV is adjusted accordingly.
21 CFR 101.9(c)(7)(i) The “corrected amount of protein (gram) per serving” for foods represented or purported for adults and children 1 or more years of age is equal to the actual amount of protein (gram) per serving multiplied by the amino acid score corrected for protein digestibility. If the corrected score is above 1.00, then it shall be set at 1.00. The protein digestibility-corrected amino acid score shall be determined by methods given in sections 5.4.1, 7.2.1, and 8.00 in “Report of the Joint FAO/WHO Expert Consultation on Protein Quality Evaluation,” except that when official AOAC procedures described in paragraph (c)(7) of this section require a specific factor other than 6.25, that specific factor shall be used. For foods represented or purported to be specifically for infants through 12 months, the corrected amount of protein (grams) per serving is equal to the actual amount of protein (grams) per serving multiplied by the relative protein quality value. The relative protein quality value shall be determined by dividing the subject food protein PER value by the PER value for casein. If the relative protein value is above 1.00, it shall be set at 1.00.
