Organo-mineral composition of grains of quinoa grown in the Cerrado of the Brazilian central plateau

Abstract

This study aimed to evaluate the proximate composition of quinoa grown in the central plateau of the Brazilian Cerrado during the summer and winter periods. Grains of the Kancolla, BRS Piabiru, and BRS Syetetuba varieties were evaluated for parameters such as moisture, dry matter, ash, protein, lipids, carbohydrates, crude fiber, calcium, magnesium, phosphorus, sulfur, and potassium. It was observed that the proximate composition of quinoa grains varies depending on the cultivation period, with higher averages in the summer. However, in both periods, the Brazilian averages were higher than those reported in the worldwide literature for quinoa grains. Regarding the mineral components, grains grown in the summer period had higher levels than in the winter, when compared to the worldwide standards for quinoa. The BRS Syetetuba variety showed superiority in the levels of the evaluated parameters compared to the other varieties.
