Nutritional quality of the protein in quinoa (Chenopodium quinoa, Willd) seeds
Plant Foods for Human Nutrition, 1992The nutritional quality of protein in quinoa seeds has been determined by amino acid assay and by animal feeding experiments. The amino acid composition of the protein in raw quinoa and washed quinoa show similar pattern. The first limiting amino acids were the aromatic amino acids thyrosine + phenylalanine giving a chemical score of 86 for protein in ...

Triterpene Saponins from Debittered Quinoa (Chenopodium quinoa) Seeds
Journal of Agricultural and Food Chemistry, 2002Twelve triterpene saponins have been isolated from the debittered seeds of quinoa (Chenopodium quinoa), and their structures were characterized on the basis of hydrolysis and spectral data, especially NMR evidence. Among them, three compounds, including 3-O-beta-D-glucuropyranosyl oleanolic acid (1), 3-O-beta-D-glucopyranosyl-(1-->3)-alpha-L ...

Physical Properties of Quinoa Seeds
Biosystems Engineering, 2003Abstract Physical properties of quinoa (Chenopodium quinoa Willd.) seeds were determined as a function of moisture content. In the moisture range from to 4·6 to 25·8% dry basis, the 1000-seed mass increased from to 2·5 to 3·1 g, the sphericity from 0·77 to 0·80, the density from 928 to 1188 kg m−3, the porosity from 0·19 to 0·44, the angle of repose ...

Electrophoretic Characterization of Quinoa Seed Proteins
Plant Breeding, 1990AbstractQuinoa (Chenopodium quinoa Willd) is an important domesticated food crop of the Andean highlands with potential as an alternative crop elsewhere. Among its most attractive characteristics are the quantity and favorable amino acid balance of the seed proteins.

The Seed Storage Proteins of Quinoa
1997Quinoa (Chenopodium quinoa) is a member of the Chenopodiaceae, or goosefoot, family of dicotyledenous plants (Figure 1). Indigenous to the Andean region of South America, cultivated quinoa is grown primarily in the cool, semi-arid altiplano of Bolivia and Peru but is also adaptable to valleys and coastal foothills. Quinoa has been a staple food item in

A compositional study of Chenopodium quinoa seeds
Food / Nahrung, 1992AbstractIn order to estimate the economic and nutritional value of plants from Peru we examined quinoa (Chenopodium quinoa, var. Perlada), grown in the north of Peru. Our results show a good content and quality in proteins and lipids of the seed of quinoa.

Content of fat, vitamins and minerals in quinoa (Chenopodium quinoa, Willd) seeds
Food Chemistry, 1993The seed of an important food crop, indigenous to the Andean region of Latin America, called quinoa (Chenopdium quinoa, Willd) is a good source of thiamin (0·4mg100 g), folic acid (78·1 mg100 g), and vitamin C (16·4 mg100 g). The seeds contain twice as much γ-tocopherol (5·3 mg100 g) as α-tocopherol (2·6 mg100 g) and larger amounts of calcium (874 mg ...

Properties of starch and dietary fibre in raw and processed quinoa (Chenopodium quinoa, Willd) seeds
Plant Foods for Human Nutrition, 1994We investigated certain properties of starch in raw and in heat-treated samples of quinoa, properties that are of importance to the nutritional quality of an infant food currently being developed. Scanning electron microscopy of the starch in raw seeds showed polygonal granules (0.6 to 2.0 microns diameter) to be present both singly and as spherical ...

Biological Effects of Hydrolyzed Quinoa Extract from Seeds of Chenopodium quinoa Willd.
Journal of Medicinal Food, 2011An extract from seeds of Chenopodium quinoa Willd. (quinoa), termed hydrolyzed quinoa (HQ), was obtained by enzymatic hydrolysis from seeds of the quinoa variety BRS-Piabiru. Analysis of the physical and chemical properties of quinoa and HQ showed that the hydrolyzed extract is rich in essential amino acids, particularly those with branched chains ...
