Abstract

Quinoa (Chenopodium quinoa willd.) is an annual herbaceous flowering plant showing appropriate nutritional and functional properties due to its high quality protein with a wide amino acid spectrum, particularly rich in lysine. The mature quinoa seed predominantly consists of 11S-type globulin called chenopodin, comprising about 37% of the total protein, and also 2S albumin accounting for 35% of the seed protein both stabilized through disulfide bridges. Moreover, quinoa seed contains low concentration of prolamins (0.5-7% of total protein) making it suitable for patients with celiac disease. Different enzymatic, chemical and physical modification methods also can influence the structural and finally nutritional and functional properties of protein isolate. Consequently, considering appropriate nutritional and functional properties of quinoa protein, it can be considered as a good candidate to supply human food products.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
