Abstract

In this investigation, chemical, microbiological and organoleptical characteristics of Stizostedion lucioperca dried in the sunand in the hot air dryers and then stored at 4°C for 60 days. It was determined that pH values of the samples dried in the sun were lowerthan pH values of the samples dried in the hot air dryers (p<0,05). In the samples dried at 65°C and high air current, total psychrophilicaerob microorganisms and yeast-mould number were found the lowest statistically (p<0,05). And also coliform bacteria was notdetermined. There was no important effect of drying process statistically (p>0,05) on total mesophilic aerob microorganisms, MicrococcusStaphylococcus, lactic acid bacteria, pH, TVB-N, aw and salt content. In the view of the general acceptance, texture, colour andappearance, the samples dried at 55°C and high air current was given highest points (p<0,05). It may be said that drying in the hot airdryers at high temperature and air current could be used as an alternative drying process, especially organoleptical properties and dryingtime, in drying of Stizostedion lucioperca
