Maize, wheat, amaranth, rice and soybean were screened for protein content. Alcohol-soluble (A1 and A2) and glutelin (G1 and G2) fractions were isolated and compared in terms of their amino acid and protein compositions. The average proportions of nitrogen content between total alcohol-soluble proteins (TASP) and total glutelins (TGlu) in the pseudocereals amaranth and soybean were about 1.8:26.9 and 14.9:12.3 respectively. In the cereals maize and wheat these proportions were 47.8:33.2 and 44.7:31.2 respectively. The sum of essential amino acids was 47.6 and 60.3g per lOOg protein in amaranth and soybean respectively. The highest contents of methionine, lysine and arginine were found in the pseudocereals. The relatively high content of essential amino acids shows that pseudocereals could be used as a nutrient substitute for cereals. Les allergenes et les inhibiteurs enzymatiques, bien connus dans les cereales, sont absents dans les pseudocereales comme l'amarante et le soja. Dans cette etude, les fractions proteinees du mais, ble, riz, amarante et soja sont examinees et comparees pour leur composition en proteines et en acides amines. Les teneurs les plus elevees en methionine, lysine et arginine sont observees dans les pseudocereales. Leurs teneurs relativement elevees en acides amines essentiels montrent que les pseudocereales peuvent etre utilises comme substituts de cereales.

- Nutraceutical value of kiwicha (Amaranthus caudatus L.) (2020, background): “One of the reasons of these high quality is due to the availability of 65% of total proteins in the embryo (rich in lysine) of the seed and only the 35% in the perisperm (poor in lysine), on the contrary to other cereal seeds which concentrates its proteins in the perisperm (85%) (Das, 2016; Gorinst”
- Applications of quinoa (Chenopodium quinoa Willd.) and amaranth (Amaranthus spp.) and their influence in the nutritional value of cereal based foods. (2012, background): “They contain less glutamic acid and proline than prolamins, and more essential amino acids such as lysine, methionine + cystine, and histidine (Table 2), resulting in a well-balanced amino acid composition for pseudocereal proteins[29],[36].”
- Amaranthus: A Promising Crop of Future (2016, background): “Main storage protein fractions, such as prolamins in cereals and globulins in pseudocereals were investigated by several workers (Konishi and Yoshimoto 1989 ; Ker et al. 1993 ; Gorinstein et al. 2002 ).”
