SALVADOR-MARTINEZ, Guadalupe et al. Compositional characteristics of amaranth species used as vegetables. Rev. Mex. Cienc. Agríc [online]. 2024, vol.15, n.8, e3094.  Epub 20-Maio-2025. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v15i8.3094.

There are few studies on the nutritional quality of young plants of the different species of the genus Amaranthus. The objective was to evaluate the nutritional quality of plants of the species Amaranthus hypochondriacus L., A. cruentus L., and A. hybridus L. grown in the municipalities of Zapotitlán de Méndez and Tochimilco, in the state of Puebla and the municipality of Temoac, Morelos, Mexico. The evaluation included forty-three genotypes classified by species and use in 11 accessions of A. hypochondriacus for grain, 12 of A. hypochondriacus for vegetables, 8 of A. cruentus for grain, and 12 of A. hybridus for vegetables. The trial was established in 2019 in Zapotitlán de Méndez, Puebla, Mexico. The plants were cut 40 days after sowing, then dried, ground and stored to perform a proximate analysis to the samples. It was found that there were no differences (p≤ 0.05) between accessions with use as grain and as vegetables in most of the variables measured, except for neutral detergent fiber and dry stem weight. Between species, there were only differences (p≤ 0.05) in acid detergent fiber, neutral detergent fiber, and ash. Between accessions, there were differences (p≤ 0.05) in all variables, except for dry leaf weight, dry stem weight, and total dry weight. The outstanding accessions to be used as vegetables due to their high content of crude protein and low content of acid detergent fiber and dietary fiber were AV17, AV28, AV29, AV31 and Benito.
