In this study, partially puriWed lysozyme was incorporated into zein Wlms in combination with chickpea albumin extract (CPAE), bovine serum albumin (BSA) and disodium EDTA. The zein Wlms showed an inherent free radical scavenging activity. Incorporation of lysozyme did not contribute to soluble free radical scavenging activity of zein Wlms. However, the incorporation of lysozyme in combination with CPAE increased the soluble and immobilized free radical scavenging activity of zein Wlms 17% to 25% and almost 84%, respectively. The incorporation of CPAE also improved the distribution of partially puriWed lysozyme preparation in zein Wlms and enabled the controlled release of lysozyme by reducing its release rate from zein Wlms between 1.5-and 3.5-fold, depending on the concentration of incorporated CPAE. In contrast, the BSA incorporation made distribution of lysozyme more heterogeneous and it did not contribute to the free radical scavenging activity of Wlms signiWcantly. The combinational incorporation of partially puriWed lysozyme with disodium EDTA · 2H 2 O or CPAE and disodium EDTA · 2H 2 O gave zein Wlms eVective on Escherichia coli and Bacillus subtilis. This study clearly showed the beneWts of using functional protein extracts to control lysozyme distribution and release rate and to improve antioxidant activity in zein Wlms.

In this study some quality characteristics and mixograph parameters of some durum wheat (Triticum durum L.) varieties and advanced lines were investigated and the relationship between them was determined. The material used in the study was grown in rainfed and irrigated conditions in 2016-2017 growing period at Bahri Dağdaş International Agricultural Research Institute. Some physical, chemical and rheological properties of durum wheat samples as well as some mixograph parameters (peak time (PT), peak height (PV), right peak slope (RPS), final peak width (CT), peak area (TINT) area (TTINT) and mixograph scale (MS) were examined. When durum wheat samples were evaluated in terms of MS which is an important indicator of gluten strength, Eminbey (7.5), Meram (6.0) and Selçuklu (5.25) varieties were found above the average (4.38). Positive correlation was obtained between PT and SDS (0.862), DDT (r=+0.791), STB (r=+0.862); and negative correlation was obtained between DS12 (r=-0,848). Positive correlation was obtained between PV and SDS (r=+0.654), DDT (r=+0.425) and STB (r=+0.483). Positive correlation was obtained between CT and SDS (r=+0.820), DDT (r=+0.681) and STB (r=+0.824) TINT and SDS (r=+0.855), DDT (r=+ 0.726) and STB (r=+0.853) and significant at p<0.01, statistically. In this study, with the use of a mixer, a small amount of sample was obtained in a short time about the quality of durum wheat. However, this subject will contribute to the use of mixograph device in durum wheat with further studies.

Yıldırım, T. (2020). Ekmeklik buğday (Triticum aestivum) genotiplerinin gluten kalitesinin glutopik cihazı ile değerlendirilmesi.

Dünyada ve ülkemizde bitkisel proteinin ana kaynağını oluşturan yemeklik dane baklagiller, beslenmede oldukça önemli yer tutmaktadır. Bu araştırma 2018 ve 2019 yıllarında 12 farklı kuru fasulye genotipi ile Konya lokasyonunda, tesadüf blokları deneme desenine göre 2 tekerrürlü olarak yıllar ve genotiplerin kalite üzerine etkilerinin araştırılması amacıyla yürütülmüştür. Çalışma sonucunda, su alma indeksi hariç incelenen diğer özellikler bakımından yıllar ve genotipler arasında (P<0.01) ve (P<0.05) seviyesinde istatistiksel anlamda farklılıklar belirlenmiştir. Araştırmada kullanılan fasulye genotiplerinin kalite özelliklerinin ortalama değerleri; nem oranı % 10.44-11.01, protein oranı %19.99-22.50, kuru ağırlık (%14 nem) 29.92-51.54 g, yaş ağırlık 67.32-111.93 g, kuru hacim 76.50-98.50 ml, ıslak hacim 162.75-188.75 ml, su alma kapasitesi 0.36-0.59 g/tane, şişme kapasitesi 0.36-0.47 ml/tane, şişme indeksi % 1.85-2.43 ve su alma indeksi % 1.09-1.18 arasında değişmiştir. İncelenen kalite değerlerine genotip özellikleri ile yıl faktörlerinin etkisinin önemli olduğu tespit edilmiştir.
