Effect of buckwheat flour on cooking quality and some chemical, antinutritional and sensory properties of erişte, Turkish noodle.

In this study, wheat flour used in erişte production was replaced with whole buckwheat flour (BWF) up to a 40% level to improve the nutritional properties of erişte. The chemical composition, phytic acid content, color values, cooking quality and sensory properties of erişte samples were determined. High levels of BWF in erişte formulation increased the ash, cellulose and fat content when compared with a control made by wheat flour. The 40% BWF supplementation instead of wheat flour decreased the starch content from 65.4% to 58.4%. Increasing the BWF level in the erişte sample resulted in an expected increase (P<0.05) in the phytic acid content and potassium, magnesium and phosphorus amounts. Significant decreases were observed in water uptake and volume increase values with BWF addition levels over 20%. BWF gave darker erişte samples in color. erişte containing BWF up to a 25% level were appreciated by the panelists, especially in terms of overall acceptability.
