Yuksel, F.
In this study, traditional homemade noodles were enriched with raw flaxseed and some nutritional properties such as resistant starch (RS), total starch, total dietary fibre (TDF), estimated glycaemic index (eGI) and major mineral composition of final products were investigated. Flaxseed was supplemented into the noodle mixture at three different concentrations (10, 15 and 20 g/100 g). RS content of the samples was in the range of 0.61-2.14 g/100 g and the highest RS was found for the sample having 10% flaxseed. Maximum TDF value was determined to be 8.28% for the noodle sample enriched with 20% of flaxseed while that of control was 1.68%. Estimated eGI of the samples was not significantly affected by the flaxseed fortification while mineral composition of noodle samples was significantly affected by the flaxseed addition (P < 0.05). The major mineral compounds present in the samples were sodium, potassium, magnesium and phosphorus. It could be concluded that the noodle enriched with 10% of flaxseed would be a healthier alternative product for consumption.

Yuksel, F.; Campanella, O.H.
The aim of this study was to analyse the effects of the addition of einkorn, cranberry bean and potato flours on the pasting characteristics of the mixture as well as the rheological properties of the dough formed. An experimental design using a simplex lattice mixture design was employed. The pasting parameters of the samples increased with the addition of cranberry bean and einkorn flours due to their high protein content. The water absorption capacities of the doughs were significantly affected by the polar nature (e.g. potato flour) and protein content (e.g. cranberry bean) of the flours. The creep-recovery properties of the doughs were analysed using the Burger model. Results showed that doughs enriched with potato flour exhibited weak elastic properties and behaved as a highly viscous material. Textural profile analysis of the doughs showed that their structure became firmer with addition of einkorn, cranberry bean and potato flours. The determination coefficient for the samples was higher than 0.70 in the simplex lattice mixture design.

Karaman, S.; Yilmaz, M.T.; Toker, O.S.; Yuksel, F.; Kayacier, A.; Dogan, M.
In this study, the effect of apple fibre with different levels of fibres (5, 10, 15 and 20%) was investigated on viscoelastic nature and the textural properties of wheat chips dough using stress relaxation test and texture profile analysis. Apple fibre addition changed the stress relaxation properties of wheat dough, depending on fibre concentration. Increase in the fibre concentration increased resistance of the dough samples to the deformation by increasing their elasticity. Hardness and gumminess values increased while springiness, cohesiveness and resilience values decreased as apple fibre level increased. Significant correlations were found between stress relaxation and texture profile analysis parameters. In order to describe the effect of apple fibre on the viscoelastic properties of wheat dough, generalised Maxwell, Nussinovitch and Peleg models were fitted to experimental stress relaxation data. All three models were found to be efficient in describing the stress-relaxation behaviour of wheat dough; but, the Maxwell model was the most effective. In addition, power-law and exponential functions were successfully used to describe the effect of apple fibre concentration on the constants related with stress relaxation data and textural parameters.

Yuksel, F.; Karaman, S.; Kayacier, A.
In the present study, wheat chips enriched with barley flour at different concentrations (5, 10, 15, 20, 25 and 30%) were produced and some physicochemical and textural properties, fatty acid composition and sensory quality of enriched chips were investigated. An increase in the values of some physicochemical parameters of wheat chips, namely hardness, dry matter, ash and some fatty acids levels, was observed with the increasing barley flour concentration in the formulation. Barley flour addition provided a significant oil uptake reduction as the oil content of the control sample was 27.23% while that of the enriched samples with 30% barley flour was 18.21%. Overall acceptability of wheat chips added with no barley flour samples was determined to be similar to compared to enriched ones. But addition of barley flour higher than 10% caused a decrease in sensory scores of the final products.
