Tarhana, a traditional fermented cereal food in Turkey, is mainly prepared with wheat flour and yoghurt. Buckwheat is a major ingredient in the daily diet of the celiac patients due to its gluten-free composition. In this research, gluten-free tarhana samples were prepared with buckwheat flour (BWF), rice flour and corn starch. Control tarhana was made of wheat flour. In gluten-free formulations, instead of wheat flour, 40% BWF, 30% rice flour and 30% corn starch in the first formulation and 60% BWF, 20% rice flour and 20% corn starch in the second formulation were handled. BWF substitution at a 60% level increased the ash and fat contents of tarhana samples, but affected the lightness value of the samples negatively. Potassium, magnesium and phosphorus contents of the gluten-free tarhana increased significantly (P <0.05) with increasing amount of BWF in the formulation. Sensory evaluation showed that BWF addition resulted in changes in consistency, taste, sourness and grittiness. Tarhana containing 40% BWF received the highest taste and overall acceptability scores.
