Nutritional Composition of quinoa and amaranth accessions of the National Bank Qermplasm Grains Andean high

Abstract

In the present investigation, the nutritional composition of accessions of quinoa and amaranth, from the National Bank of High Andean Grains was determined. For this purpose, 35 accessions of quinoa and 35 accessions of amaranth were used, with a weight of 100 g per accession. The nutritional value analyzes were carried out in the Quality laboratory of the INIAF. The variables determined were: crude protein, macroelements (phosphorus, potassium, sodium, calcium and magnesium in amaranth and also the same in quinoa with the exception of calcium) and microelements (iron, manganese, zinc, copper and boron). For its analysis of the indicated variables, univariate statistical methods (descriptive statistics) and multivariate statistical methods (cluster analysis) were applied. The crude protein fluctuated between 11.9 to 23.5% for quinoa and 13.5 to 19.1% for amaranth. In potassium the highest averages were 1476.9 mg / 100 g of quinoa and 602 mg / 100 g of amaranth; in iron the highest averages were 9 mg / 100 g of quinoa and 11 mg / 100 g of amaranth. Also, based on the statistical analysis of conglomerates, three groups were identified for quinoa and amaranth. In the same, with regard to protein content, Group III was distinguished by an accession of quinoa (2.8%) with an average of 23.5% and Group II comprised of 12 amaranth accessions (34%) with an average of 16, 3%. The outstanding accessions in terms of protein and mineral content, of these two species studied, invite to enhance their production technology and in parallel their disclosure of their importance as high nutritional value foods.
