Popis: Budic-Leto I., Humar I., Zdunic G., Hribar J., Zlatic E. (2015): Volatile compounds in Prosek dessert wines produced from white and red grapes. Czech J. Food Sci., 33: 354–360. Prosek dessert wines produced from dried grapes of two native Croatian varieties, one white and one red, had complex volatile compositions. Various categories of volatile compounds were identified using headspace solid-phase micro extraction (HS-SPME) coupled to gas chromatography-mass spectrometry (GC-MS). Sixty-one individual volatile compounds of Prosek were identified. Of these, nine compounds comprised over 95% of the total peak area of volatile aromas detected in Prosek: five esters and four alcohols. The remaining volatile compounds consisted of 11 alcohols, 11 esters, 10 terpenes, 8 aldehydes, 10 ketones, 4 acids, 1 lactone, and 1 norisoprenoide. Only 13 of the 61 aroma compounds showed significant differences between the varieties investigated. These results suggest that the charac teristic aroma of Prosek is very complex and determined predominantly by the unique process of the grape drying.
