Özet
Raisin production and export is an important business in Turkey. In this research V. vinifera L. cv. “Sultanina” was dried in polythene tunnel type rack systems solar drier and in direct sunlight (traditional drying method). The inside temperature of the tunnel has been increased by adding solar panels to the drying tunnel. The cluster of grapes was dipped in four different alkali solution (dipping solution); such as 1%, 2%, 3%, and 5% of sodium hydroxide + 1% olive oil. Each application was two replicates and at each repetition to be 2 kg/m2 grapes. After dipping grapes were placed on the rack. Drying process were continued until 14% humidity. In the study drying period of the grapes, drying ratio, % moisture, % total soluble solids content, 100 berry weight, berry surface color (CIE, L, a, b), alcohol-soluble color values were measured.
