Abstract (2. Language): 
In this study, Izmir gevrek -highly consumed at the breakfasts- was enriched with dairy proteins by using dairy products (Izmir tulum cheese, milk powder and whey powder)at different levels and 5 mm thick disc-shaped sliced gevrek was dried at three different temperatures (140, 150 and 160°C) in a convection oven. The drying characteristics of snacks were examined with six different thin-layer drying models that are commonly used in literature. The Page model gave a better fit to experimental drying data and had the highest adjusted R-square with the lowest reduced chi-square and root mean square error values as compared to other models. The effective diffusion coefficient was calculated and the activation energy was derived from Arrhenius equation.

Abstract (Original Language): 
Bu çalışmada, kahvaltılarda sıkça tüketilen İzmir gevreği, farklı oranlarda süt ürünleri (İzmir tulumu, süt tozu ve peynir altı suyu tozu) kullanılarak proteince zenginleştirilmiş ve 5 mm kalınlığa sahip disk şeklinde dilimlenen gevreklere 140, 150 ve 160°C’de konveksiyonlu fırında kurutma işlemi uygulanmıştır. Çerezlerin kuruma davranışları literatürde sıkça kullanılan 6 farklı ince tabaka kuruma modeli ile incelenmiştir. Denenen modeller arasında Page modelinde en yüksek düzeltilmiş belirleme katsayısı ile en düşük indirgenmiş ki-kare ve en düşük kök ortalama kare hatası değerleri elde edilmiştir. Çerezlerin etkin difüzyon katsayıları hesaplanmış olup, Arrhenius eşitliği ile aktivasyon enerjileri belirlenmiştir.
