Abstract

Quinoa (Chenopodium quinoa Willd.) is attracting worldwide attention due to its nutritional and biological properties. Nowadays, this pseudocereal is cultivated worldwide in different environmental conditions. This work evaluates the nutritional profile, polyphenol content and antioxidant capacity of five quinoa cultivars (Negra, Chullpi, Salcedo, Pasankalla and Kancolla) from Spain and from the Andean region, looking for the key factor of quinoa composition. Nutritional profile was similar for the same cultivar among the locations but, protein and iron contents were higher (p< 0.05) in Spanish seeds compared to the Andean ones. PCA and Pearson correlation coefficient reveal that the darkest quinoa cultivars, Negra and Pasankalla, had the best bioactive profile because the major dietary fiber, polyphenol content, and antioxidant capacity that were found higher (p< 0.05), regardless of origin zone. Concluding, the genetic variability seems to have a higher influence than the geographic factors on the nutritional and antioxidant composition of quinoa.
