Abstract：
:This study was carried out to determine the protein content of several Amaranthus sp. grains. Findings revealed this has a high lysine (5.3 to 6.3 of the protein) and sulphur amino acids content (3.4-4.0%), while leucine could well be limiting when those seeds are used as a sole protein source in food. Using the correction for in vitro protein digestibility, the chemical score varied from 50 to 67. The calculated protein efficiency ratios and biological values ranged from 1.39 to 1.80 and 53 to 68, respectively. Considering that amaranth grain is a good supplement to cereal grain, the protein of A. hypochondriacus HH5 (yellow seeds) and A. anclancalius (black seeds) was fractionated into albumin, globulin, prolamin and glutelin. The average proportions between those soluble proteins were 65:17:11:7, respectively. Albumin had the highest lysine content (7.3-8.2%), and globulin the highest methionine (4.1-5.3%) and phenylalanine (6.0-6.1%) content. Prolamin had the highest threonine (4.6-5.4%) and leucine (6.8-6.9%) content, while glutelin had a very low methionine content (0.6-1.0%). Based on the above-mentioned findings, the authors conclude the variation in the amino acid composition of the protein fractions can be used for genetic protein improvement.
