摘要(Abstract)：
金华火腿和巴马火腿分别经同时蒸馏(SDE)和固相微萃取(SPME)法提取,用气-质联用仪对其进行分析,结果表明:醇、醛、酮、酯、烷烃、含硫及杂环化合物是两种干腌火腿的共有成分,且其风味组成相似,但各成分的含量存在明显差异。重要的火腿香味物质3-甲基丁醛、戊醛、己醛、庚醛、苯乙醛、2-辛烯醛、壬醛、辛醛、2,3-辛二酮、乙酸乙酯、1-辛烯-3-醇和癸酸等均由两种方法检出。两种方法均检出金华火腿中醛类和酸类含量较巴马火腿多,而巴马火腿中醛类和烷烃类或醇类的含量较金华火腿多。两种火腿采用两种方法检出的风味物质不同之处在于SPME法检出金华火腿的酸类物质种类和含量均较巴马火腿高,而SDE法检出巴马火腿的醇类物质的种类和含量均较金华火腿高。
