Anamur muz halkalarının osmo-solar kuruma davranışının belirlenmesi için yanıt yüzey yönteminin kullanılması

Abstract

Aims: In this study, banana rings were dried by a solar tray dryer together with osmotic dehydration called osmosolar dehydration. It was aimed to predict osmosolar dehydration drying conditions by Response Surface Method (RSM).Methods and Results: Banana rings were firstly immersed in sucrose solution and then dried in a solar dryer. Inputs as drying conditions were chosen as solution concentrations, slice thickness, immerse time and solar drying time. Also, outputs are chosen as water loss, shrinkage ratio and yellow color change. The results clearly showed that both water loss and shrinkage ratio have increased due to increased solar drying time and immerse time.Conclusions: The correlation coefficient (R2) values of the water loss, shrinkage ratio and yellow color change for the RSM model were respectively found as 0.979, 0.930 and 0.920.Significance and Impact of the Study: Anamur Banana, which has high moisture content and drying temperature, was dried using a combination of osmotic dehydration and solar drying. Pretreatment of osmotic dehydration was found to be effective in dried banana rings with solar tray dryer.
