中文摘要: 通过喷雾干燥技术制备百香果果粉,采用顶空固相微萃取-气相色谱质谱联用技术(Head Space-Solid Phase Micro Extraction-Gas Chromatography-Mass Spectrometry,HS-SPME-GC-MS),并结合保留指数法(Retention Index,RI) 验证辅助定性,以及峰面积归一化法确定比较各组分的相对含量,分析瞬间热干燥技术对百香果风味成分的影响。结 果表明,喷雾干燥所制得果粉复溶果汁与原果汁对比分析后,两者风味成分基本类似,比例有较大变化。经热处理后 的果粉仍具有主要风味成分,与原果汁风味相似。同时由于产生了新物质,带来了更多的风味变化。喷雾干燥所得百 香果果粉基本可以保证持有原有风味,并为后续深入研究贮藏过程中风味动态变化研究奠定基础。

Abstract:The research aimed to obtain the comparison and analysis of the original juice and the redissolution juice prepared by spray drying powder from Passiflora edulia Sims. The flavor compositions were identified by head space-solid phase micro extraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS), com- bined with retention index (RI) aided qualitative analysis, and determined by area normalization method. The results showed that the constituents of two kinds of juice from Passiflora edulia Sims had proved broadly similar. The powder prepared by spray drying also had retained the main flavor components, which was similar to the o- riginal one. Moreover, there were more flavor components with the new substances created. The powder pre- pared by spray drying can be assured to retain the original flavor. It is established foundation for further studies on the dynamic changes of flavor during storage.
