In-vitro digestibility, protein digestibility corrected amino acid, and sensory properties of banana-cassava gluten-free pasta with soy protein isolate and egg white protein addition

Food Science and Human Wellness, 2023
Soy protein isolate and egg white protein were added to cassava-banana gluten-free pasta and the effects on the nutritional quality, digestibility properties, protein digestibility corrected amino acid (PDCAA), and sensory acceptance of the pasta was ...

Investigation of the genetic determinism of amino acid digestibility traits in Duroc×Landrace×Yorkshire crossbred pigs [PDF]

Animal Bioscience
Objective The objective of this study was to delineate the genetic architecture of ileal amino acid digestibility in Duroc×(Landrace×Yorkshire) hybrid (DLY) pigs through genome-wide association study (GWAS).

A comparison of digestible amino acid databases: Relationship between amino acid concentration and digestibility

Journal of Applied Poultry Research, 2012
SUMMARY Databases compiling the amino acid (AA) digestibility values of 20 common poultry feed ingredients from 2 commercial companies, Evonik Degussa (Burr Ridge, IL; chick assays) and Ajinomoto Heartland (Chicago, IL; rooster assays), were used to investigate the influence of AA concentration on observed digestibility values.

Determination of True Ileal Amino Acid Digestibility in the Growing Pig for Calculation of Digestible Indispensable Amino Acid Score (DIAAS) [PDF]

Journal of Nutrition, 2020
Digestible indispensable amino acid score (DIAAS) has been recommended by the FAO for the evaluation of protein quality in human foods, but the application of DIAAS is currently limited because of a lack of published data on the true ileal amino acid (AA) digestibility of AAs in foods. The importance of DIAAS is highlighted.

Protein and amino acid digestibility: definitions and conventional oro-ileal determination in humans [PDF]

Frontiers in Nutrition
When assessing protein quality, a correction needs to be made to take into consideration the availability of the amino acids. This correction is based on the digestibility of the amino acids.

Dietary methionine level alters growth, digestibility, and gene expression of amino acid transporters in meat-type chickens

Poultry Science, 2020
: Imbalance in nutrients can affect digestibility of amino acids by altering gene expression of amino acid transporters. We investigated digestibility and molecular transporters of essential amino acids in chickens fed a methionine-deficient diet.

Digestible indispensable amino acid score and digestible amino acids in eight cereal grains [PDF]

British Journal of Nutrition, 2014
To determine values for the digestible indispensable amino acid score (DIAAS), it is recommended that ileal amino acid (AA) digestibility values obtained in growing pigs are used to characterise protein quality in different foods. Therefore, an experiment was conducted to determine the standardised ileal digestibility (SID) of AA in eight cereal grains

The amino acid composition of human milk corrected for amino acid digestibility [PDF]

British Journal of Nutrition, 1998
Human milk was collected from women in their 10th–14th weeks of lactation, and was analysed for amino acids. Corrections were made for losses of amino acids which were presumed to occur during acid hydrolysis, using a non-linear mathematical model that describes the simultaneous processes of amino acid yield and decay.

A Rat Study to Evaluate the Protein Quality of Three Green Microalgal Species and the Impact of Mechanical Cell Wall Disruption

Foods, 2020
The present study was conducted to evaluate the protein quality of microalgae species Chlorella vulgaris (CV), Chlorella sorokiniana (CS), and Acutodesmus obliquus (AO) and assess the impact of mechanical cell wall disruption.
