Effects of the dietary addition of Amaranth (Amaranthus mantegazzianus) protein isolate on antioxidant status, lipid profiles and blood pressure of rats
(Springer, 2015-12)
The effects of the dietary addition of 2.5 % (w/w) Amaranthus mantegazzianus protein isolate (AI) on blood pressure, lipid profiles and antioxidative status of Wistar rats were evaluated. Six diets were used to feed animals ...
Prevention of in vitro oxidation of low density lipoproteins (LDL) by amaranth peptides released by gastrointestinal digestion
(Elsevier, 2017-07)
The objective of this work was to analyze the capacity of amaranth peptides generated by gastrointestinal digestion to prevent LDL oxidation. A simulated gastrointestinal digest from protein isolate (Id); Id fractions ...
Amaranth lectins present potencial antitumor properties
(Elsevier Science, 2015-01)
The possibility of reducing the risk of cancer is one of the most important challenges facing scientists. In this work we demonstrate that the amaranth lectin presents potential antitumor activity and we propose a mechanism ...
Interfacial and emulsifying properties of amaranth (Amaranthus hypochondriacus) protein isolates under different conditions of pH
(Elsevier Science, 2012-01)
Amaranth proteins have adequate amino acid balance for substituting either partly or completely animal proteins in human nutrition. However, they present poor emulsifying properties in basic conditions corresponding to ...
Amaranth proteins emulsions as delivery system of Angiotensin-I converting enzyme inhibitory peptides
(Elsevier, 2019-05)
We analyze the possibility of using the emulsifying properties of amaranth proteins and the bioactivity shown by peptide sequences encrypted in these proteins to formulate functional emulsions with angiotensin I-converting ...
Antiproliferative effect of amaranth proteins and peptides on HT-29 human colon tumor cell line
(Springer, 2019-01)
Antiproliferative effect of Amaranthus mantegazzianus proteins and peptides released after simulated gastrointestinal digestion (DH% 37.8 ± 3.8) was investigated on human colon cancer cell line (HT-29). Inhibition of ...
Amaranth peptides from simulated gastrointestinal digestion: antioxidant activity against reactive species
(Springer, 2015-03)
We evaluated the capacity of simulated gastrointestinal digests or alcalase hydrolysates of protein isolates from amaranth to scavenge diverse physiologically relevant reactive species. The more active hydrolysate was ...
Stability of oil: Water emulsions of amaranth proteins: Effect of hydrolysis and pH
(Elsevier, 2010-08)
In this contribution we have determined the effect of limited enzymatic hydrolysis on the emulsifying capacity of amaranth proteins. The action of enzyme (alcalase and trypsin) and the pH of the continuous phase of the ...
Antithrombotic and Antioxidant Activity of Amaranth Hydrolysate Obtained by Activation of an Endogenous Protease
(Springer, 2016-06)
Ingestion of diets with antithrombotic and antioxidant components offer a convenient and effective way to prevent and reduce the incidence of cardiovascular diseases. The aim of the present work was to obtain an amaranth ...
Amaranth, quinoa and chia protein isolates : physicochemical and structural properties
(Elsevier, 2018)
Abstract: An increasing use of vegetable protein is required to support the production of protein-rich foods which can replace animal proteins in the human diet. Amaranth, chia and quinoa seeds contain proteins which have ...
