Öğe Improvement of chemical properties of noodle and pasta using dephytinized cereal brans(Elsevier, 2020) Levent, Hacer; Koyuncu, Mehmet; Bilgicli, Nermin; Adiguzel, Emre; Dedeoglu, MustafaIn this research, cereal brans (rice, rye, wheat and oat) were dephytinized by two different methods (phytase enzyme and malt flour) and used in noodle and pasta formulation (20%) to improve nutritional quality of the final product. As a result of phytase treatment, phytic acid content of different bran samples decreased between 70.9 and 83.5%. Rice bran noodles and pasta samples gave the highest amount of phytic acid. In general, the use of cereal bran in noodles samples increased protein and fat content compared to control noodles. The use of cereal bran increased the total dietary fiber content by 1.9-3.3 times in noodle and 1.7-2.9 times in pasta samples. All bran samples increased total phenolic content and antioxidant activity values in noodles and pasta samples (p < 0.05). The amount of Ca, P, K, Mg and Zn of cereal bran noodles and pasta samples was higher than control noodles and pasta samples (p < 0.05). In addition to nutritional enrichment, it was concluded that the noodles and pasta samples with a lower phytic acid content can be produced using dephytinized cereal brans.Öğe Use of durum wheat clear flour in vital gluten and bioethanol production(Academic Press Ltd- Elsevier Science Ltd, 2018) Sayaslan, Abdulvahit; Koyuncu, Mehmet; Turker, Selman; Irkli, Yavuz; Serin, Abdullah; Orhan, Fatma GulsahDuring milling of durum wheat (Triticum durum) into semolina used for pasta processing, certain amount of clear flour (5-15%) with low economic value is obtained. This study aimed at determining the suitability of durum clear flours for vital gluten and bioethanol productions. The durum clear flours were wet-processed into vital gluten by three wet-milling methods, namely dough-washing, dough-water dispersion and flour-water dispersion. Vital glutens with acceptable purities (71.0-82.1% protein, Nx5.7, dm), yields (9.8-14.3%, dm) and recoveries (48.7-76.8%) were achieved by the dough-water and flour water dispersion methods. However, vital gluten by the dough-washing method could not be isolated satisfactorily. The dough mixing and breadmaking qualities of vital glutens from the clear flours were found comparable to the commercial vital gluten. The carbohydrate-rich remnants of the clear flours upon isolation of glutens were subjected to enzymatic hydrolysis and yeast fermentation, leading to ethanol yields and conversion efficiencies of 32.2-33.5% (g/g, based on clear flour solids) and 80.5 -87.6%, respectively. In conclusion, except for the dough-washing method, vital gluten and bioethanol with acceptable purities, yields, recoveries and qualities can be produced by the dough-water and flour water dispersion methods.
