Document Summary
Chemical score = 1st limiting eaa (mg) in food / eaa (mg) in reference. The amino acid in shortest supply during protein synthesis, or lowest quantity when evaluating protein quality. 47: protein efficiency ratio, measures amino acid composition and accounts for digestibility, measured in test animals. Per = weight gain (g) / protein intake (g) [high quality protein: net protein utilization, measures how much dietary protein the body actually uses. Npu = (nitrogen retained / nitrogen intake) x 100: measuring nitrogen excreted, nitrogen intake: test food, biological value, how much nitrogen absorbed from a particular food"s protein is retained for growth/maintenance. Bv = (nitrogen retained / nitrogen absorbed) x 100% Egg protein, bv = 100: corn protein, bv = 60, protein digestibility corrected amino acid score (pdcaas) 1989 joint fao/who expert consultation on protein quality evaluation: accounts for amino acid composition of a food and digestibility of the protein. Established standard: protein needs of pre-school aged children.
