  2. Protein digestibility corrected amino acid score - Wikipedia

    en.wikipedia.org/wiki/Protein_Digestibility...

    This score means, after digestion of the protein, it provides per unit of protein 100% or more of the indispensable amino acids required. 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]

  3. Amino acid score - Wikipedia

    en.wikipedia.org/wiki/Amino_acid_score

    By using an amino acid score, it can be indicated if a protein will meet all amino acid needs of the body. If the amino acid score meets the required score it will be a completed or ideal protein. 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 ...

  4. Digestible Indispensable Amino Acid Score - Wikipedia

    en.wikipedia.org/wiki/Digestible_Indispensable...

    Amino acid requirements were determined in two parts. The amino acid distribution of breast milk was used for the 0 to 6 month age range, and existing amino acid data was used for older ages after adjustment for digestibility. The reference amino acid requirements are presented below. [2]: 29

  5. Protein quality - Wikipedia

    en.wikipedia.org/wiki/Protein_quality

    The Protein Digestibility Corrected Amino Acid Score (PDCAAS), which was recommended by the Food and Agriculture Organization of the United Nations (FAO), became the industry standard in 1993. FAO has recently recommended the newer Digestible Indispensable Amino Acid Score (DIAAS) to supersede PDCAAS.

  6. List of foods by protein content - Wikipedia

    en.wikipedia.org/wiki/List_of_foods_by_protein...

    The reduction of water content has the greatest effect of increasing protein as a proportion of the overall mass of the food in question. Not all protein is equally digestible. Protein Digestibility Corrected Amino Acid Score is a method of evaluating the protein quality based on the amino acid requirements of humans. [1]

  7. Protein efficiency ratio - Wikipedia

    en.wikipedia.org/wiki/Protein_efficiency_ratio

    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.

  8. Protein digestibility - Wikipedia

    en.wikipedia.org/wiki/Protein_digestibility

    Protein digestibility refers to how well a given protein is digested. [1] Along with the amino acid score , protein digestibility determines the values for PDCAAS and DIAAS . See also

  9. Biological value - Wikipedia

    en.wikipedia.org/wiki/Biological_value

    Amino acid composition is the principal effect. All proteins are made up of combinations of the 21 biological amino acids. Some of these can be synthesised or converted in the body, whereas others cannot and must be ingested in the diet. These are known as essential amino acids (EAAs), of which there are 9 in humans.
