Amaranth is a pseudocereal of Andean origin, and
compared to other crops, its seeds have a higher content of proteins, lipids
and bioactive compounds of nutraceutical relevance.
The goal of the present work is to study the
chemical composition, antioxidant activity and biological value of the protein
of an advance line Amaranthus cruentus
L. seed flour (ACRU), compared with the same flour subjected to thermal
treatment (90 ºC, 1 h). Regarding the proximal chemical composition, the
protein and lipid contents stand out, reaching values of 19.59 g % and 7.47 g
%, reflecting an increase of 17% and 50% in the treated sample, respectively. A
significant increase (p<0.05) is observed in the ash content, as well as in
the content of the main elements of nutritional interest, of the treated
samples. The anti-nutrients values are within the acceptable limits in all
samples, and present an adequate content of total phenols, with an antioxidant
activity highlighted by its free-radical scavenging capacity. In the biological
tests, the Net Protein Utilization (NPU) presents lower values for the treated
samples, the True Digestibility (tD) does not show significant differences, and
the Biological Value (BV) turns out to be lower in the treated sample
(p<0.05). A significant hypotriglyceridemic effect is observed. The applied
thermal treatment, even though increases the nutrients concentration and the
total phenols, according to the biological tests, it decreases the protein quality.
These are aspects that should
