Environmental Conditions Affecting during Solar Drying of Grapes: The Case of Tunnel and Open Air-Drying.

Drying optimization, to mitigate fungal growth and (OTA) contamination is a key topic for raisin and currant production. Specific indicators of environmental conditions and drying properties were analyzed using two seedless grape varieties (-red and -white), artificially inoculated with under open air and tunnel drying. The air temperature (T), relative humidity, grape surface temperature (T) and water activity throughout the drying experiment, the grapes' moisture content and the fungal colonization and OTA contamination during the drying process and their interactions were recorded and critically analyzed.
