Abstract

Quinoa flour is becoming increasingly popular in food applications due to its increased nutritional properties and high versatility. Addition of quinoa flour in gluten-free products not only increases dietary fiber and protein content, but it also contributes essential minerals such as potassium, magnesium, calcium, and iron. Its excellent nutritional profile makes it a suitable option for its addition in gluten-free baking. However, the presence of bitter compounds in it makes it difficult to yield a high sensory acceptance. The objective of this study was to evaluate the effect of the addition of quinoa flour to gluten-free baked products and to determine a way to improve its characteristics without reducing its nutritional value. Different ratios of quinoa flour were mixed with rice flour, tapioca flour, and sorghum flour in order to determine an appropriate ratio for consumer acceptance. Three different baked products were formulated and tested: quinoa muffins, quinoa chocolate chip cookies, and quinoa crackers. It was determined that the muffin yielded the best characteristics. The reduction of quinoa flour in the formulations proved to increase the acceptability of the products. Further testing is needed in order to improve the overall acceptance of the product and improve the taste without reducing the nutritional qualities of the flour.
