Abstract Quinoa can be used as a functional ingredient in food formulations. The aim of this study was to evaluate the effects on proximate composition, stability during storage, texture and consumer acceptability of yogurts supplemented with quinoa flour at 1, 3 and 5 g 100 mL -1 . A product without supplementation was used as control. Products were assessed for moisture, carbohydrates, proteins, fats, total dietary fibre (TDF), ashes and minerals. The pH, acidity and syneresis of yogurts were measured after 1, 7, 14 and 21 days of storage and a Texture Profile Analysis (TPA) was carried out. Applying hedonic scale, 102 consumers analyzed the overall acceptability, color, texture, flavor and aroma of yogurts. Supplemented products showed significant higher protein, carbohydrate and fat contents. Hardness and adhesiveness showed a negative association whereas a positive one was found between springiness and cohesiveness. Yogurt is not necessarily the adequate matrix for hauling quinoa compounds since the addition of greater amounts of 1 g 100 mL
