摘要
采用毛细管气相色谱法测定了不同年份赤霞珠干红葡萄酒中甲醇、乙酸乙酯、高级醇的含量。结果表明,随着贮藏时间的延长,甲醇含量逐渐降低,乙酸乙酯含量逐渐升高,高级醇含量逐渐升高,异戊醇含量最高,约占所测得高级醇总量的69%。测定的样品中甲醇含量为122.37~207.12 mg/L,乙酸乙酯含量为15.24~37.92 mg/L,高级醇总量为338.73~399.62 mg/L。对比分析贮藏时间对葡萄酒甲醇、乙酸乙酯、高级醇的影响,为提升葡萄酒品质,促进葡萄酒行业的发展奠定了基础。
The content of methanol,ethyl acetate and higher alcohols in Cabernet Sauvignon dry red wine of different age was determined by capillary gas chromatography.The results showed that,with the extension of storage time,methanol content decreased,ethyl acetate content increased gradually,and higher alcohols content increased gradually(isoamyl alcohol content was the highest,accounting for about69%of the total higher alcohols).In the measured wine samples,the content of methanol was122.37~207.12mg/L,the content of ethyl acetate was15.24~37.92mg/L,and the total amount of higher alcohols was338.73~399.62mg/L.In this paper,the effects of storage time on methanol,ethyl acetate and higher alcohols in wine were analyzed,which laid a foundation for improving the quality of wine and promoting the development of wine industry.
