摘要：The effect of skin contact time (0, 6, 12 hours at 15 °C) on the volatile compounds of Muscat of Bornova musts was investigated. Aroma compounds were isolated by liquid-liquid extraction method with dichloromethane and quantified by gas chromatography and identified by gas chromatography-mass spectrometry. A total of 31 aroma compounds including 13 terpenes, 4 six-carbon compounds, 4 higher alcohol, 2 esters and 8 acids were identified. The amount of aroma compounds, total phenolic compound, browning indices, total nitrogen and pH increased considerably with skin contact time, whereas it decreased the amount of total acidity.
