Aims: The aim of this study is to determine the effect of scalding, which is applied as a thermal pre-dryingprocess, on the solar drying process of banana rings.
Methods and Results: In this study, scalding method was applied as a thermal pretreatment. The blanched banana rings were then dried in a natural convective solar tray dryer. Water and citric acid in concentrations between 2.5-10% were used as scalding solution. The banana rings were scalded at a 80°C temperature and then dried in a solar dryer. The effects of drying conditions such as scalding solution concentration, scalding time and drying time in solar dryer on moisture loss, diametrical shrinkage rate and change in b color parameter were determined. Thermal pretreatment was found to be effective in dryingthe banana rings with the solar tray dryer. With the pre-treatment applied before solar drying, moisture loss and diametrical shrinkage rate of the banana rings increased during the drying period, and b yellow color change was observed to decrease.
Conclusions: Drying food products by exposing them to direct sunlight is a widely used traditional economic drying method. Since the solar drying process takes place at low temperature, the sensory properties and nutrient content of the product to be dried are partially preserved. The scalding pre-drying process applied before drying in the solar dryer can be applied as it provides more moisture loss in a shorter time and prevents color change.
Significance and Impact of the Study: Mersin province is one of the provinces that has a significant contribution to the country's economy, especially in fruit production. As well as Mersin has a high radiation potential, it ranks first in banana production. Economical and ecological drying process can be done by taking advantage of the heating effect of the sun and the positive effect of scalding.
