摘要: 采用分子蒸馏法(短程分子蒸馏器)富集甜橙精油中的特征香气成分,如癸醛、辛醛、芳樟醇及巴伦西亚桔烯等,同时采用气相色谱-质谱联用法进行检测。通过各参数优化比较,最终确定分子蒸馏条件为温度30℃、压力150Pa、转速200r/min、流速8mL/min。在此条件下,各成分富集结果为辛醛(由0.46%提高到1.55%)、癸醛(由0.59%提高到9.11%)、芳樟醇(由0.71%提高到5.84%)、巴伦西亚桔烯(由0.24%提到高7.96%)。分子蒸馏技术可用于甜橙油特征香气成分的高效富集。

Abstract: A molecular distillation method was developed to enrich characteristic aroma compounds including octanal, linalool, decanal and valencene in sweet orange oil, while gas chromatography-mass spectrometry (GC-MS) was used for detection. The optimum parameters of molecular distillation were: temperature of 30 ℃; pressure of 150 Pa; rotation speed of 200 r/min and flow rate of 8 mL/min. Under such an optimum condition, the enrichment results were: octanal (0.46%→ 1.55%), linalool (0.71%→5.84%), decanal (0.59%→9.11%) and valencene (0.24%→7.96%). Finding here reveals that molecular distillation technique is promising in the fast and effective enrichment of the characteristic aroma compounds in citrus oil.
