ROMANI-MORON, María Julia  e  VALDEZ-ARANA, Jenny del Carmen. Effect of habitat change on the nutritional and functional characteristics of 16 quinoa (Chenopodium quinoa Willd.) accessions cultivated in the Peruvian Coast. Scientia Agropecuaria [online]. 2019, vol.10, n.2, pp.293-302. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2019.02.15.

The aim objective was evaluated the effect of habitat change on some nutritional and functional characteristics of 16 accessions of quinoa with different content of saponins, collected in the Sierra of Cuzco (3237 m.a.s.l.) and cultivated in the Coast of Lima (235 m.a.s.l.) in Peru was evaluated. Quinoas were washed, dried and ground, for further analysis. The average amount of proteins (18.21±1.00%), ashes (3.33±0.51%) and total dietary fiber (12.94±1.40%), of the crops of the Coast, were significantly higher (p value <α (0.05)), than their original homologs of the Sierra (15.68±1.57%, 2.40±0.23% and 10.56±1.01% , respectively); while the average amount of Carbohydrates (69.74±1.32%), in vitro starch digestibility levels (46.97±23.40%) and in vitro protein digestibility levels (63.62 ± 4.32%), were significantly lower than the original quinoas of the Sierra (72.19±3.01%, 59.16±23.94%, 67.21±6.28%, respectively). Fat, fiber, total polyphenol content and antioxidant capacity levels did not show significant changes when changing habitat. The habitat change is proved to be an influence on some nutritional and functional characteristics of the quinoa beans.
