| Free and glycosidically bound aroma compounds of the Narince wines and the effect of skin contact treatment (15 degrees C, 12h) on aroma composition have been investigated during two vintages. Free and bound aroma compounds were extracted with dichloromethane and Amberlite XAD-2 resin, respectively, and then analysed by gas chromatography (GC) and gas chromatography mass spectrometry (GC-MS). According to the results obtained in both vintages, Narince wines were characterized by the presence of high level of fermentative aroma compounds (higher alcohols, fatty acids, and esters, respectively), and skin contact treatment increased the total concentration of free and bound volatiles. |

| Esters are important contributors to cheese flavor, but their mechanisms of synthesis in cheese are largely unknown. This study aimed to determine whether ethanol concentration limits the formation of ethyl esters in cheese. Mini Swiss cheeses were manufactured with (E) or without (C) the addition of ethanol to cheese milk. Ethanol concentrations (enzymatic analysis) were 64 ± 17 and 330 ± 82 g g-1, respectively, in C and E cheeses. E cheeses also contained 5.4 ± 2.3 times more of the five ethyl esters quantified than C cheeses, regardless of the concentrations of esters in C cheeses (range 1-128 ng g-1). Furthermore, the presence of propionibacteria added as acid-producing secondary starters was associated with greater concentrations of esters, due to the... |
