Abstract

In this study, sun-dried eggplant samples were rehydrated at three different rehydration water temperatures (25, 35and 45°C) and the effect of rehydration kinetics were determined. Four different models were used to model therehydration behaviors of sun-dried eggplants, and non-linear regression analysis were performed to obtain the modelthat gives the best fit to experimental data. The coefficients of models were calculated. According to regressionanalysis, Peleg model gave a better fit for all rehydration conditions applied. Additionally, the effective diffusivitieswere between 3.21×10-8 and 4.06×10-8 m2 s-1. Rehydration water temperature influenced rehydration rates, andmoisture uptake of samples was faster at high temperatures.

Özet

Çalışmada, güneşte kurutulmuş patlıcan örneklerinin rehidrasyonunda, üç farklı rehidrasyon suyu sıcaklığının (25, 35 ve 45°C) rehidrasyon kinetiğine etkisi incelenmiştir. Dört farklı modelle, rehidrasyonda elde edilen deneysel sonuçların uygunluğu doğrusal olmayan regresyon analizi uygulanarak karşılaştırılmış ve modellere ait katsayılar hesaplanmıştır. Deneysel sonuçlara en iyi uyum gösteren modelin Peleg modeli olduğu belirlenmiştir. Çalışmada ayrıca efektif difüzivite katsayıları da belirlenmiş ve 3.21×10-8 - 4.06×10-8 m2 s -1 değerleri arasında hesaplanmıştır. Yüksek sıcaklıkta yapılan rehidrasyon işleminde nem kazanımının daha hızlı olduğu belirlenmiştir.
