Descripción
Sumario: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.
