摘要:

利用固相微萃取和气相色谱技术对赤霞珠干红葡萄酒中的主要香气成分进行分析,采用单因素和响应曲面法进行试验设计,以香气值为研究指标,研究SPME 的萃取时间、萃取温度和电解质(NaCl)的添加量等因素对红葡萄酒中主要芳香物质的影响。结果表明:最佳分析参数是时间30.50min、温度45℃、加盐量0.29g/mL,并对结果进行验证,在此条件下,香气值之和提高了6.1。

Abstract:

Major aromatic components in red wine were analyzed by solid-phase micro-extraction and gas chromatography (SPME-GC). Effects of extraction time, extraction temperature and NaCl concentration on major aromatic components in red wine were explored by single-factor and response surface experiments. Results indicated that the optimal parameters of SPMEGC analysis were extraction time of 30.50 min, extraction temperature of 45 ℃ and NaCl concentration of 0.29 g/mL. Under the optimal conditions, total aroma value was increased by 6.1 folds.
