摘要: 采用固相微萃取装置提取千山产软枣猕猴桃采后20℃条件下外释香气成分,用气质联用法从中分离并确认化学成分,并测定采后20℃条件下硬度、可溶性固形物的变化。结果表明,硬度从采时的6.60kg/cm2降到第10天的0.95kg/cm2,可溶性固形物则从8.50%升到11.45%;软枣猕猴桃采后20℃贮藏2、4、6、8、10d,鉴定出香气成分分别为6、12、15、15、15种,香气成分种类呈增加趋势;从软枣猕猴桃中共检测鉴定出22种化学成分,其主要成分为:萜品油烯、β-蒎烯、4-异丙基甲苯、D-柠檬烯、α-蒎烯。

Abstract: The released aroma components of Actinidia arguta (Sieb. et Zucc) fruits grown in Qianshan Mountain were extracted by solid-phase microextraction (SPME), separated and identified by gas chromatography-mass spectrometry (GC-MS). The changes in hardness and soluble solid content of Actinidia arguta were also analyzed during storage at 20 ℃. The results showed that the hardness of freshly picked fruits was 6.6 kg/cm2 and dropped to 0.95 kg/cm2 on the 10th day, soluble solid content rose from 8.50% to 11.45%. After 2, 4, 6, 8 days and 10 days of storage, 6, 12, 15, 15 kinds and 15 kinds of aroma components were identified. A total of 22 compounds were identified from Actinidia arguta, and the major aroma components are terpinolene, β-pinene, p-cymene, D-limonene and α-pinene.
