Abstract

In this study, drying characteristics of the capia pepper slices were investigated using a food drying oven. Prior to drying process of the peppers, the peppers were pretreated with a mixture of hot NaOH solution and olive oil / K2CO3 mixture. The pre-treated and non-pretreated pepper samples were dried in the food drying oven at temperatures of 50 and 60 ° C. It was observed that the applied pre-treatment and the increasement in the drying temperature decreased the drying time and changed the rehydration capacity. At 50 ˚C, the effective diffusion coefficients of the chickens dried by pre-treatment with NaOH and olive oil/K2CO3 pretreatments were 1.62 × 10-10, 3.24 × 10-10 and 8.11 × 10-10 m2s-1, respectively. At 60 ˚C, they were calculated as 3.24 × 10-10, 4.87 × 10-10 and 9.74 × 10-10 m2s-1 respectively. Activation energy values ​​were calculated as 57.62, 33.88 and 15.23 kj, respectively. In addition, thermodynamic analyzes of drying processes were carried out and cumulative consumed energy amounts were determined for each drying temperature and the pretreatment applied.

Özet

Bu çalışmada, kapya biber dilimlerinin kurutma karakteristikleri bir konvektif sıcak havalı kurutucu kullanılarak incelenmiştir. Biberlerin kuruma işleminden önce, sıcak NaOH çözeltisi ve zeytinyağı/K2CO3 karışımı ile ön işleme tabi tutulmuştur. Ön işleme tabi tutulan ve herhangi bir ön işleme tabi tutulmayan biber numuneleri, gıda kurutma fırınında 50 ve 60°C sıcaklıklarda kurutulmuştur. Uygulanan ön işlemin ve kurutma sıcaklığındaki artışın, kuruma süresini azalttığı ve rehidrasyon kapasitesini değiştirdiği görülmüştür. 50 ˚C sıcaklıkta ön işlemsiz, NaOH ve zeytinyağı/K2CO3 ön işlemleri uygulanmasıyla ile kurutulan kapya biberlerin efektif difüzyon katsayıları sırasıyla 1,62×10-10, 3,24×10-10 ve 8,11×10-10 m2s-1, 60 ˚C sıcaklıkta ise sırasıyla 3,24×10-10, 4,87×10-10 ve 9,74×10-10 m2s-1 olarak hesaplanmıştır. Aktivasyon enerjisinin değerleri ise sırasıyla 57,62, 33,88 ve 15,23 kj olarak hesaplanmıştır. Ayrıca kurutma işlemlerinin termodinamik analizleri de yapılarak her bir kurutma sıcaklığı ve uygulanan ön işlemler için kümülatif tüketilen enerji miktarları belirlenmiştir.
