Antioxidant Activity of Free and Bound Compounds in Quinoa ( <i>Chenopodium quinoa</i> Willd.) Seeds in Comparison with Durum Wheat and Emmer

Abstract

Quinoa seeds may represent an excellent source of natural antioxidant compounds and, in particular, of the free-soluble antioxidant fraction. These compounds may improve nutritive and health-beneficial properties of quinoa-based gluten-free products, thus expanding interest for quinoa utilization from celiac patients to the general population.
