摘要: 应用固相微萃取技术与气相色谱-质谱相结合的方法对南果梨果皮与果肉、完整果外释与破碎后果汁的香气成分进行比较和研究。结果表明,完整果实的外释香气成分种类比破碎后果汁中的香气成分种类丰富,从完整果实外释香气共鉴定出18种香气成分,主要为乙酸乙酯(1.49%)、丁酸乙酯(7.48%)、2-甲基丁酸乙酯(1.43%)、己酸甲酯(1.46%)、己酸乙酯(41.76%)、乙酸己酯(11.78%)、2-辛烯酸乙酯(1.07%)、辛酸乙酯(6.73%)、和α-法呢烯(21.6%)。南果梨果皮和果肉中有5种共同香气成分,但相对含量上有一定的差异。果皮和果肉中的香气成分相对含量最高的是己酸乙酯,分别为46.89%、35.2%。

Abstract: The aroma components of Nanguo pear peel, pulp, intact fruit and cracked fruit were determined by solid phase micro- extraction (SPME) and gas chromatography-mass spectrometry (GC-MS). The intact fruit contained more kinds of aroma components than the cracked fruit. Eighteen aroma components were identified in the intact fruit, mainly including ethyl acetate (1.49%), butanoic acid, ethyl ester (7.48%), acetic acid, 2-methylpropyl ester (1.43%), hexanoic acid, methyl ester (1.46%), hexanoic acid, ethyl ester (41.76%), acetic acid, hexyl ester (11.78%), 2-octenoic acid, ethyl ester (1.07%), octanoic acid, ethyl ester (6.73%) and alpha-farnesene (21.6%). There were 5 aroma components common to both the peel and pulp of Nanguo pear with a difference in the relative contents. The most abundant compound in the peel and pulp was ethyl caproate, accounted for 46.89% and 35.2%, respectively.
