摘要：The effect of skin-contact (7 h at 15 °C) on composition of free and glycosidically bound aroma compounds of Muscat of Alexandria was investigated. Aroma compounds were analysed by GC and GC-MS. 19 free (2 alcohols, 3 six-carbon alcohols, 8 terpenols, 5 acids, 1 phenol) and 37 bound (4 alcohols, 3 six-carbon alcohols, 13 terpenols, 5 acids, 4 C-13 norisoprenoids) aroma compounds were identified. With regard to free and bound compounds, the must obtained from skin contact was richer than temoin. The amount of glycosidically bound terpenol compounds was found to be higher than the free terpenol compounds. In addition, the skin-contact treatment increased the amount of potassium, total phenolic compounds (OD₂₈₀) and browning (OD₄₂₀) indices and pH value, whereas it decreased the amount of total acidity.
