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.

Key words: wine, aromatic components, SPME, OAV, response curve surface design
