In order to meet the rising demand of celiac patients for high quality and healthier products, the old biotechnological process, sourdough technology, was applied in gluten-free bread-making. In present study, the effect of addition of different amounts of sourdough (0%, 20% and 40%, % flour basis) on the rheological behaviour of the gluten-free chestnut-rice dough formulations prepared with chestnut and rice flours as well as on the quality parameters (pH, total titratable acidity (TTA), firmness and volume) of chestnut-rice breads was pointed out. The increasing levels of sourdough addition reduced pH and increased TTA values of samples. The addition of sourdough decreased complex modulus (G*) of dough samples showing softening of dough. The highest specific volume and the lowest firmness values were obtained from gluten-free breads with the addition of 20% sourdough. However, higher level (40%) of sourdough addition had detrimental effect on volume and firmness of breads. The results of present study showed that addition of 20% of sourdough can be used to improve the quality of gluten-free chestnut-rice breads.

Utilization of chestnut flour in gluten-free bread formulations Demirkesen, Ilkem; Mert, Behiç; Şümnü, Servet Gülüm; Şahin, Serpil (2010-12-01) In this study, gluten-free bread formulations using chestnut and rice flours at different ratios (0/100, 10/90, 20/80, 30/70, 40/60, 50/50 and 100/0) were tested. In addition, the influence of hydrocolloid blend (xanthan-locustbean gum (LBG), xanthan-guar gum blend) and emulsifier DATEM on the rheological properties of dough formulations and quality parameters of breads were also investigated for the samples having chestnut/rice flour ratio of 10/90, 20/80, 30/70 and 40/60. Herschel-Bulkley model was found ...
Development of gluten-free wafer sheet formulations MERT, Selen; Şahin, Serpil; Şümnü, Servet Gülüm (2015-10-01) The main objective of this study was to develop gluten-free wafer sheet formulations by replacing rice flour partially with different gluten-free flours at different ratios. Rice-corn flour blends, rice-buckwheat flour blends and rice-chestnut flour blends with different ratios (80:20, 60:40, 40:60) were used in the experiments in order to find the higher quality and more nutritional gluten-free wafer sheet formulations. As a control, wafer sheet samples containing only rice flour and only wheat flour were ...
Utilization of chestnut flour in gluten-free cakes Demirkesen, Ilkem; Sumnu, Gulum; Şahin, Serpil (2011-12-01) The inappropriate immune response to the certain grain proteins in wheat, barley, rye and possibly oat is called celiac disease. In order to produce gluten-free products, many scientists and manufacturers used flours obtained from different sources such as corn, soy, sorghum, buckwheat and chickpea. Furthermore, ingredients and gums such as emulsifiers, enzymes, dairy products, fibers and hydrocolloids were used to improve functional properties of gluten-free products. Chestnut flour can be a good alternati...
Quality of Gluten-Free Bread Formulations Baked in Different Ovens Demirkesen, Ilkem; Şümnü, Servet Gülüm; Şahin, Serpil (2013-03-01) The objective of this study was to determine the effects of different tigernut flour/rice flour ratios (0:100, 5:95, 10:90, 15:85, 20:80, and 25:75) on quality of gluten-free bread formulations baked in infrared-microwave combination and conventional ovens. The degrees of the starch gelatinization of breads baked in different ovens were also compared. Conventionally baked breads prepared with tigernut flour/rice flour ratio of 10:90 and the infrared-microwave combination-baked breads prepared with tigernut/...
Development of gluten-free bread formulations for baking in infrared-microwave combination oven Demirkesen Mert, İlkem; Şümnü, Servet Gülüm; Şahin, Serpil; Department of Food Engineering (2013) The main objective of this study was to formulate gluten free breads based on different flours, gums, and emulsifiers for baking in infrared-microwave combination oven. In the first part of the study, the rheological properties of different gluten-free bread dough formulations containing only rice flour and rice-chestnut flour blend with different gums, gum blends and/or emulsifiers were evaluated. Power law model and Herschel–Bulkley models were found to explain the flow behaviors of rice and chestnut-rice...
