The content of protein and non-protein (free and protein-bound) tryptophan in Theobroma cacao beans
Stability of quinoa flour proteins (Chenopodium quinoa Willd.) during storage.
Summary The amino acid composition and the physicochemical and functional properties of quinoa flour proteins (QFP) were evaluated during storage (at 20, 30 and 40 � C). Quinoa flour showed a protein…
The importance of heat against antinutritional factors from Chenopodium quinoa seeds
TLDR
In vitro digestibility evaluation indicated that heat-treated samples showed a more complete digestion than the native state samples, and quinoa seeds can be an important cereal in human diet after adequate heat treatment.
Characterization of Proteins from Grain of Different Bread and Durum Wheat Genotypes
The classical Osborne wheat protein fractions (albumins, globulins, gliadins, and glutenins), as well as several proteins from each of the four subunits of gliadin using SDS-PAGE analyses, were…
Utilization of quinoa flour in cookie production

Phytase activity and comparison of chemical composition, phytic acid P content of four varieties of quinoa grain (Chenopodium quinoa Willd.)
TLDR
The aim of this research was to investigate the relations between phytic acid P content and phytase activities of varieties quinoa Narino-Colombia (QC), quinoa Anapquins-Bolivia (QBA) and quinoa Huancavelica-Peru (QP), and found significant differences in the proportions of protein, fat, fibre, and ash among the four varieties.
Functional Properties of the Protein Isolate and Major Fractions of Pine Nut Proteins Prepared from the Changbai Mountain in China

Non-targeted metabolomics of quinoa seed filling period based on liquid chromatography-mass spectrometry.
Study of some physicochemical and functional properties of quinoa (chenopodium quinoa willd) protein isolates.
TLDR
Analysis of DSC, fluorescence, and solubility data suggests that there is apparently denaturation due to pH, and some differences were found that could be attributed to the extreme pH treatments in protein isolates and the nature of quinoa proteins.

Seed Lipid Content and Fatty Acid Composition of Three Quinoa Cultivars
TLDR
The purpose of this research was to determine the seed lipid content and fatty-acid composition from three genetically diverse cultivars of quinoa, which appears to be a high quality edible oil, similar in fatty- acid composition to soybean oil.

Some thoughts on amino acid supplementation of proteins in relation to improvement of protein nutriture.
TLDR
Evaluation of proteins or protein mixtures should be determined under the conditions of their potential use, which could lead to the development of a protein replacement equivalents system similar to the starch equivalents system in the evaluation of the net energy of animal feeds.
Control through breeding methods of factors affecting nutritional quality of cereals and grain legumes.
TLDR
The plant breeder attempting to develop higher-yielding, disease-resistant and nutritionally-improved crop varieties should be aware of such a complex of factors and alert to the possible production of undesirable products or deleterious changes in chemical composition.
