Article Citation - WoS: 20Citation - Scopus: 26Quality, Nutritional Properties, and Glycemic Index of Colored Whole Wheat Breads(MDPI, 2023-09-08) Koksel, Hamit; Cetiner, Buket; Shamanin, Vladimir P.; Tekin-Cakmak, Z. Hazal; Pototskaya, Inna V.; Kahraman, Kevser; Morgounov, Alexey I.The main aim of this study was to investigate the quality and nutritional properties (dietary fiber, phenolic, antioxidant contents, and glycemic index) of breads made from whole wheat flours of colored wheats. White (cultivar Agronomicheskaya 5), red (Element 22), purple (EF 22 and Purple 8), and blue (Blue 10) colored wheats were used in the study. The whole wheat flours of Blue 10 and Purple 8 had higher farinograph stability, lower softening degree, and higher quality numbers indicating that they had better rheological properties. Bread produced from whole wheat flour of blue-colored grain had significantly higher loaf volume and better symmetry, crust color, crumb cell structure, and softness values among others (p < 0.05). The whole wheat bread produced using Element 22 had the highest crust and crumb L* color values, while Purple 8 and EF 22 had the lowest crust and crumb L* color values, suggesting that purple-colored grains have a tendency to make whole wheat bread with darker crust and crumb color. Bread produced from cultivar Blue 10 had the lowest firmness values while Element 22 had the highest firmness values. The highest total phenolic content and antioxidant capacity values were obtained from the whole wheat bread sample from purple-colored wheat (Purple 8). The whole wheat flour of Element 22 had the highest total dietary fiber content among all samples (p < 0.05). The differences between whole wheat bread samples in terms of total dietary fiber and glycemic index were not statistically significant. The results of the present study indicated that colored wheats can be used to produce whole wheat breads with higher nutritional properties and acceptable quality characteristics.Article High Carbohydrate Diet Decreases Microbial Diversity and Increases Il-1β Levels in Mice Colon(Korean Society Food Science & Technology-kosfost, 2024-05-04) Ulutas, Mehmet Sefa; Aydin, Erkin; Cebeci, AysunWestern diet is known to contribute to intestinal dysbiosis and the progression of inflammation. Although the Turkish diet has different macronutrient contents, the intestinal inflammatory disease incidences in T & uuml;rkiye are comparable to Western countries. Thus, we hypothesized that high carbohydrate diets also contribute to inflammation of the colon. We compared diets with different macronutrient compositions and investigated their effects on colonic microbiota, cytokine, histology, and tight junction protein levels. High carbohydrate diet caused the lowest microbial diversity and is accompanied by the highest expression of interleukin-1 beta and claudin-1. A low carbohydrate diet with zero fiber resulted in the lowest inflammatory markers as well as the lowest occludin and claudin levels. Overall, our results indicate that carbohydrate and fiber contents of the diets are important contributors to colon health.Article Citation - WoS: 11Citation - Scopus: 15Effects of Extrusion Cooking on the Nutritional Quality of Puffed Snacks Made From Blends of Barley and Green Lentil Flours(Springer, 2023-06-02) Li, Xiang; Franczyk, Adam; Kahraman, Kevser; House, James D.; Koksel, FilizIncreasing demand for nutritionally dense foods warrants the investigation of high fiber and protein ingredients in snack food applications. In this study, blends of barley (22.9% dietary fiber, db) and green lentil (26.4% protein, db) flours were extruded at five blending ratios (barley: green lentil, 100: 0, 75: 25, 60: 40, 45: 55, 0: 100, db), two barrel temperature profiles (60-130 degrees C and 70-140 degrees C from feeder to die) and three feed moisture contents (15, 18 and 21%) to produce puffed snacks. Extrusion significantly improved in vitro protein digestibility (IVPD) of all blends by up to 10%. Decreasing feed moisture and increasing die temperature improved IVPD. Blending increased the limiting amino acid score and hence improved the in vitro protein digestibility corrected amino acid score (IVPDCAAS) of extrudates. On average, the blend 45:55 showed the highest average IVPDCAAS (68.62%) among the blends studied and lower glycemic index scores compared to the blend 60: 40. In general, extrusion did not substantially affect the soluble, insoluble or total dietary fiber contents of the blends. All extrudates from blends 60: 40 and 45:55 met the requirement to be labelled as "good source of dietary fiber" in the US.
