Abstract: | Tarhana was supplemented with buckwheat flour (BWF) to improve its nutritional value and functional properties. Some physical, chemical, functional and sensory properties of tarhanas containing BWF (20%, 40%, 60% 80% and 100%) were determined and compared with the control sample. Fermentation loss of tarhana varied between 9.06% and 23.27%. Ash, protein, fat and cellulose contents of the tarhana increased with high BWF addition levels. The high phytic acid content (1565 mg/100 g) of BWF decreased up to 98.7% proportion during the tarhana process. As the BWF addition level increased, K, Mg and P contents of tarhana increased significantly (p < 0.05). 40% BWF addition increased lysine content significantly (p < 0.05). While nutritional value of tarhana increased with BWF addition, functional and sensory properties decreased over 40% addition level. |
