摘要: A modified headspace solid phase microextraction (HS-SPME) method was compared with Amberlite® XAD-2 resin for the extraction of volatile compounds. In HS-SPME method, volatiles were extracted using an 85 [mu]m polyacrylate fiber from wines that contained a standardized amount ethanol (10% v[solidus]v), NaCl (0.325 g[solidus]mL) and internal standards (dodecanol nonanoic acid). Both procedures yielded high relative recoveries (>92%) reproducibilities (coefficient variations = 11%) different higher alcohols, esters medium-chain fatty acids. Overall, limits detection methods below sensory threshold concentrations. performed similarly in analysis Riesling wine; however, did not require organic solvents generally quicker to perform. applying differences concentrations compounds produced Chenin blanc by 11 yeast strains noted.
