Resumen:

Amaranth seeds have a high content of bioactive compounds with a remarkable nutritional and nutraceutical positive potential for human health. Their composition includes key proteins, some interesting essential amino acids, lipids, carbohydrates, dietary fiber, and important phytochemicals. Over the last few decades amaranth has been considered the most promising plant due to its agronomic performance, protein quality, and essential amino acids of their seeds being superior to other important cereals. Globulins are the main protein fraction containing valuable amounts of essential amino acids. When amaranth proteins are subjected to enzymatic proteolysis by food processing, bioactive peptides are released and their absorption may bring benefits to health. The functional properties of the bioactive peptides, including their antihypertensive and antioxidant properties, may prevent the onset of cardiovascular diseases and favor other outstanding health benefits. The use of prediction of sequence peptides and other molecular tools is giving place to genetic transformation and modifications which may lead to the improvement of the nutraceutical potential of these proteins. © 2017 Elsevier Inc.
