The study tested 160 products from 70 top protein powder brands, though neither the products nor brands were named in the report. The sample pool represented 83% of the market, the report read.
Unlike some measures of protein usability, biological value does not take into account how readily the protein can be digested and absorbed (largely by the small intestine). This is reflected in the experimental methods used to determine BV. BV uses two similar scales: The true percentage utilization (usually shown with a percent symbol).
Protein quality is the digestibility and quantity of essential amino acids for providing the proteins in correct ratios for human consumption. There are various methods that rank the quality of different types of protein , some of which are outdated and no longer in use, or not considered as useful as they once were thought to be.
The formula for calculating the PDCAAS percentage is: (mg of limiting amino acid in 1 g of test protein / mg of same amino acid in 1 g of reference protein) x fecal true digestibility percentage. [2] The PDCAAS value is different from measuring the quality of protein from the protein efficiency ratio (PER) and the biological value (BV) methods. [3]
The report tested 160 products from 70 of the top-selling protein powder brands representing 83% of the market. Of the products tested, ...
The PDCAAS considers the global digestibility of the product's protein (a single figure) while the DIAAS accounts for a specific digestibility percentage for each indispensable amino acid The reference values for the PDCAAS are based on a unique age group, the 2 to 5-year-old child which is deemed to be the more demanding.
