Zamalloa-Puma Luisa Colque-Condeña Ingeniería Quinoa proteins bioactives germinated quinoa antioxidant activity Quinoa (Chenopodium quinoa Willd) is a pseudocereal with a high nutritional potential and a significant content of bioactive compounds, which is consumed mainly by the inhabitants of the South American Andes. The aim of this study was to evaluate the protein content, total phenols, and antioxidant activity of quinoa grains of the Salcedo INIA, Pasankalla, and Negra collana varieties, germinated for 24 and 48 hours at 35 °C. Organic quinoa grains were grown in the Andahuaylas province in Peru, at an altitude of 3582 m. The protein content was determined through the Kjeldahl method, total phenols, in turn, by spectrophotometry with the Folin-Ciocalteu reagent, and the antioxidant activity of the DPPH type were registered. The data were analyzed through an Analysis of Variance (ANOVA), a Tukey test, and Pearson's correlation at 5% significance. The germinated quinoa grains showed a considerable increase (p < 0,05) in their protein content, total phenolic compounds, and antioxidant activity, as well as a strong positive correlation with the size of sprouts during the germination time. Therefore, germinated quinoa could be considered as a promising product for human nutrition and health. 2021 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64379873009 https://www.redalyc.org/journal/643/64379873009/ https://www.redalyc.org/journal/643/64379873009/html/ https://www.redalyc.org/journal/643/64379873009/64379873009.epub https://www.redalyc.org/journal/643/64379873009/movil 10.15446/ing.investig.v41n2.89831 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.2 Vol.41 |
