Yuksel, Ferhat; Kayacier, Ahmed
Wheat chips enriched with stale bread were produced and response surface methodology was used for the studying the simultaneous effects of stale bread level (0-50 g/100g), frying temperature (170-190 °C) and frying time (40-60 s) on some physicochemical, chemical, textural, morphological and sensorial properties of chips. Additionally, product optimization was performed by using ridge analysis to detect the optimum levels of process variables. The dry matter, ash, Hunter Lab a and b values of samples increased with the increasing stale bread level. Higher frying temperature caused a decrease in the hardness and water activity values. Also, addition of stale bread in the formulation of chips decreased the oil uptake of samples significantly (p < 0.01). Sensory values of wheat chips increased with the increasing stale bread level. In general, panelists preferred wheat chips enriched with stale bread compared to control sample. The addition of stale bread made the structure of chips firm and electron microscopy analysis revealed that pores and fractures of chips decreased for the samples containing stale bread, which resulted in lower oil uptake during frying.

Yuksel, Ferhat; Karaman, Kevser
In the present study, production and using possibilities of powder of macaroni boiling water (PMBW) were investigated. After cooking process of macaroni, firstly pre-drying was carried out at 50°C in a drying oven and then lyophilization process was conducted to obtain final powder product. Physicochemical characterizations like total dry matter, ash, fat, protein, pH, aw and color properties were carried out and also technological properties of sample were determined. Both macaroni boiling water and the final powder product were examined in terms of microbiological analyses. It was found that macaroni boiling water had to be processed in 6h after cooking if the cooking water was stored at room temperature. Also, the duration of 12h after cooking was found to be limit level for microbiological safety of cooking water if it was stored at+4°C. Besides, scanning electron micrographs of particles and fatty acid and mineral profile of the final powder product were determined. Macaroni boiling water is a by-product having a lot of nutrients and in this study it was proved that utilization of this by-product may be feasible. The macaroni boiling water can be used as a food ingredient and also as an enrichment agent.

Türkiye kaliteli makarnalık buğday üretimi yapılabilecek uygun ekolojik bölgelere sahip bir ülkedir. Ancak, ülkede makarnalık buğdayda verim ve kaliteyi artırmanın gerekliliği söz konusudur. Bu çalışmada, 3 farklı lokasyonda (Tokat-Kazova, Diyarbakır, Sivas-Ulaş) 2 yıl (2005-2006, 2006-2007) süreyle yetiştirilen 25 makarnalık buğday (Triticum durum Desf.) genotipinin temel kalite kriterleriyle ilgili stabilite özellikleri incelenmiştir. Makarnalık buğday genotipleri 12 tane tescilli ve 13 tane ileri hattan oluşmuştur. Tarla denemeleri tesadüf blokları deneme deseninde 3 tekerrürlü yürütülmüştür. Temel kalite özellikleri olarak makarnalık buğdayların protein içeriği, gluten indeksi, sedimentasyon ve spesifi k sedimentasyon hacimleri, sarı renkli pigment içeriği ve lipoksijenaz aktivitesi belirlenmiştir. Stabilite parametreleri olarak regresyon katsayısı (bi) ile regresyondan sapma kareler ortalaması (S2 d) kullanılmıştır. İncelenen tüm özellikler bakımından genotip, çevre ve genotipxçevre interaksiyonları önemli (P < 0.01) bulunmuştur. Tüm kalite özellikleri bakımından stabil bir genotip bulunamamış, bazı kalite özellikleri bakımından birkaç genotip ön plana çıkmıştır. Benzer kökenli bazı genotipler kluster analizine göre belirlenen aynı kümeler içerisinde yer almışlardır. Islah hatları arasında, Hat - 1, Hat - 7, Hat - 20 ve Gdem - 12 hatları genel ortalamanın üstünde iyi kalite özellikleri göstermeleri nedeniyle ıslah materyalleri olarak kullanılabilirler. Tescilli çeşitler arasında Aydın - 93, Çeşit - 1252 ve Gidara’nın her iki parametreye göre belli kalite özelliklerinde stabil oldukları belirlenmiştir.

Sakin, Mehmet A.; Sayaslan, Abdulvahit; Duzdemir, Oral; Yuksel, Ferhat
In this study, pastaquality- associated characteristics of 25 durum wheat genotypes were investigated. Durum wheat genotypes consisted of 13 advanced experimental lines and 12 registered cultivars that were grown in three different locations of Turkey for 2 yr. Genotype, location, year and their interactions were found to be statistically significant in terms of all investigated quality characteristics. Mean quality parameters for the genotypes varied as follows: yellowberry kernel 1.7-6.1%, pigment content 3.67-8.31 mg kg-1, lipoxygenase (LOX) activity 12.9-27.9 EU g-1, protein content 10.8-11.8% (14% mb), gluten index (GI) 12-61, sodium dodecyl sulphate-sedimentation volume 17.3-28.7 mL, specific sedimentation volume 1.60-2.52 mL. Of the genotypes, 10 contained γ-gliadin 45 and six γ-gliadin 42 proteins. Except for Zenit, none of the registered cultivars and advanced experimental lines investigated in this study were able to meet simultaneously the requirements for high-quality pasta products; yet certain experimental lines prevailing in specific quality characteristics, such as Line-Gdem- 2, Line-Gdem-12 and Line-20, may be used for further breeding purposes. The results of this study also imply that grain yield and quality should be taken collectively into consideration in wheat breeding programs.
