Abstract:

An alternative to traditional methods of drying can be used in most of developing countries. Use of solar dryers reduce the drying time up to 50 % and to a significant improvement of the product quality and the storage losses can be reduced to a minimum.This thesis was performed with three fish species common in Cambodia, namely Climbing Perch (Anabas testudineus), Spiny eel (Mastacembelus armatus) and Swamp eel (Monopterus albus). These fish samples were investigated in two variants: salted and unsalted samples as a control and were dried in three different types of dryers: electric oven, solar plastic dryer and solar hybrid dryer.Research showed statistical differences between drying behaviour of fish samples dried in electric oven and solar dryers. Saline solution had as significant impact on drying process, samples with saline pretreatment were dried faster. Contrary between selected fish species were not statistical differences. Saline solution had a statistical significant impact on the rehydration of dried samples. Samples loaded in saline solution had a smaller rehydration ratio than samples without pretreatment.
