Removing gluten from the diet is the treatment of Celiac disease and many other levels of gluten intolerance. This study determined if using gluten-free flour is an acceptable replacement for gluten-based flour.

Peanut-butter thumbprint cookies were prepared with quinoa flour (quinoa) and compared objectively/subjectively to both 100% all-purpose flour (all-purpose), which served as the control and a 50/50 mixture of all-purpose/quinoa flour (50/50). Shear force to penetrate, maximum force to withdrawal, shear force to cut and volume measurements were the objective tests performed. All objective tests presented with a significant differences (P<.05).

Approximately 30 Central Washington University students were asked to evaluate the cookies subjectively in a controlled environment. Sensory scores for difference, chewiness/tenderness, saltiness, sweetness and preference were all done on a rated scale. There were no differences between the all-purpose and 50/50 but difference presented between all-purpose and quinoa. The quinoa was a chewier, sweeter cookie than the all-purpose (P<.05). Quinoa flour showed to have attributes that are an acceptable replacement for all-purpose flour in a peanut-butter thumbprint cookie.
