  • Title: Chemical composition and bile acid binding activity of products obtained from amaranth (Amaranthus cruentus) seeds.
    Author: Tiengo A, Motta EM, Netto FM.
    Journal: Plant Foods Hum Nutr; 2011 Nov; 66(4):370-5. PubMed ID: 21901402.
    Abstract:
    Cardiovascular diseases are currently the greatest cause of mortality in the world, and dislipidemia is appearing as one of the most important risk factors. The binding of bile acids (BAs) has been hypothesized as a possible mechanism by which dietary fibers lower blood cholesterol levels. Besides the fibers, other components in the amaranth seeds may be related to this hypocholesterolemic effect. The objective of the present study was to evaluate the BA binding capacity of some products obtained from defatted amaranth flour (DAF) and from the amaranth protein concentrate (APC). The alkaline residue, rich in fibers (8.6%), presented the lowest binding activity for the BAs tested, with the exception of glycocholic acid. The DAF showed intermediary binding activity for all the BAs tested, although similar to that of the APC for deoxycholic acid, and to that of the amaranth protein hydrolysate (APH) for taurocholic acid. The DAF and APC showed binding activity for secondary bile acids toxic to the intestinal mucus. From the results, amaranth products were shown to have the ability to bind BAs, but it was not possible to affirm whether the main component responsible for this activity was the proteins, fibers or eventually some other non-evaluated component.
