PDCAAS, protein digestibility-corrected amino acid score; DIAAS, digestible indispensable amino acid score for adolescents and adults; MPC, milk protein concentrate; WPI, whey protein isolate; SPI, soy protein isolate; PPC, pea protein concentrate; RPC, rice protein concentrate.
Values from Rutherfurd et al. (1).
Values for PDCAAS from Anwar and El-Chaghaby (4).
Values for DIAAS from Reynaud et al. (5).
Values from Ahrens et al. (6).
Values from Nosworthy et al. (7).
Hydrolyzed collagen has a PDCAAS and DIAAS score of 0 since it contains no tryptophan (Trp) and is very low in methionine (8).
The author apologizes for this error and states that this does not change the scientific conclusions of the article in any way. The original article has been updated.
