Quinoa (Chenopodium quinoa Willd.) is an important seed crop throughout the Andean region of South America. It is important as a regional food security crop for millions of impoverished rural inhabitants of the Andean Altiplano (high plains).…
-
BACKGROUND: Quinoa is a good source of protein and can be used as a nutritional ingredient in food products. This study analyses how much growing region and/or seasonal climate might affect grain yield and nutritional quality of quinoa…
-
The agronomical, nutritional, physicochemical and antioxidative properties of 6 genetically different quinoa genotypes, cultivated in 3 distinctive geographical zones of Chile, were determined. Ancovinto and Cancosa genotypes from the northern…
-
Antioxidant activity (AA) of quinoa (Chenopodium quinoa Willd.) seeds, as well as of durum wheat (Triticum turgidum L. ssp. durum Desf.) and of emmer (T. turgidum L. ssp. dicoccum Schübler) grains, was evaluated by studying hydrophilic (H),…

The use of quinoa (Chenopodium quinoa Willd.) and amaranth (Amaranthus spp.) is of great nutritional interest because of their peculiar composition and the minor components present in these grains. In addition to being one of the important energy…
-
BACKGROUND: Particle-stabilised emulsions, so-called Pickering emulsions, are known to possess many beneficial properties, including being extremely stable. Starch granules isolated from quinoa have been used as emulsion stabilising particles. The…
-
Seeds with colored testa (seed coat) contain high concentrations of polyphenolic compounds that exhibit high levels of antioxidant activity. Common processing procedures, such as cooking and baking, decrease the levels of these bioactive compounds… -
Besides their well-known effect in the molting control in insects, ecdysteroids are steroid hormones that display potential pharmacologic and metabolic properties in mammals. The most common ecdysteroid, 20-hydroxyecdysone (20E) is found in many…

Quinoa farmers in San Agustin, Bolivia face the dilemma of producing for a growing international market while defending their community interests and resources, meeting their basic household needs, and making a profit. Farmers responded to a…
-
Given the broad acceptance of sour cassava starch biscuits in Brazil and the nutritional quality of quinoa flour, this study aimed to evaluate the effect of extrusion temperature, screw speed, moisture, and amount of quinoa flour on the physical…
-
A previous study showed that both Grapevine Algerian latent virus (GALV) and Tomato bushy stunt virus (TBSV) systemically infect Nicotiana benthamiana, but GALV causes systemic infection whereas TBSV causes only local lesions in Chenopodium quinoa…

Intact starch granules isolated from quinoa (Chenopodium quinoa Willd.) were used to stabilize emulsion drops in so-called Pickering emulsions. Miglyol 812 was used as dispersed phase and a phosphate buffer (pH7) with different salt (NaCl)…
-
Quinoa cultivation in Chile presents an ancient and active complex of geographic, climatic, social and cultural interactions that has determined its current biodiversity in the three main growing zones (north, central and south). Importantly, these…

Reviewing the situation of quinoa production in southern Bolivia, Jacobsen (2011, J. Agron. Crop Sci. 197: 390) argues that the booming export market has a negative effect on the environment and on the home consumption of quinoa, thereby leading to…
-
A set of 34 quinoa populations from the Northwest Argentina region was characterised using quantitative and qualitative phenotypic traits in an experiment conducted in the province of Jujuy, Argentina. A selection of quinoa descriptors from the…
-
Quinoa (Chenopodium quinoa Willd.) is believed to be tolerant to abiotic stress including salinity, drought and poor soil quality. To investigate the effect of soil type and soil-drying during the seed-filling phase on N-uptake, yield and water use,…
-
The adjuvant activity of Chenopodium quinoa (quinoa) saponins on the humoral and cellular immune responses of mice subcutaneously immunized with ovalbumin (OVA) was evaluated. Two quinoa saponin fractions were obtained, FQ70 and FQ90, and 10…
-
Despite their possible applications in diverse fields, saponins are still considered to be industrial waste. The use of saponins, however, would make seed processing more profitable and reduce the pollution of watercourses. In this work, the…
