Protein digestibility-corrected amino acid score (PDCAAS) is a method of evaluating the quality of a protein based on both the amino acid requirements of humans and their ability to digest it. The PDCAAS rating was adopted by the US FDA and the Food and Agriculture Organization of the United Nations / World Health Organization (FAO/WHO) in 1993 ...
To calculate the amino acid score the formula used is, the milligram of limiting amino acid in 1 gram of test protein/ the milligram of that same amino acid of reference protein multiplied by 100. [2] If food has a score of 100 it is to considered as a high quality protein with all the necessary nutrients.
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 There are various methods that rank the quality of different types of protein, some of which are outdated and no longer in use, or not considered as useful as they once were thought to be.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 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.
The U.S. Food and Drug Administration now uses the Protein Digestibility Corrected Amino Acid Score (PDCAAS) as the basis for the percent of the U.S. recommended daily allowance (USRDA) for protein shown on food labels. However, the PER is still used in certain FDA regulations.

Previously, electors cast two votes for president, and the winner and runner up became president and vice-president respectively. The appointment of electors is a matter for each state's legislature to determine; in 1872 and in every presidential election since 1880 , all states have used a popular vote to do so.
