Rose oil is much too expensive but very popular. It's well known that the flower oil's aroma profile hasn't been intensively investigated. In order to verify the aroma profile of rose oil, the synthetic blend of odorants was prepared and then compared with the original rose oil using electronic nose analysis (ENA) combined with quantitative descriptive analysis (QDA). The odorants from rose oils were screened out by Gas Chromatography-Olfactometry/aroma extract dilution analysis (GC-O/AEDA) combined with odour activity value (OAV). Both ENA and QDA indicated the recombination model derived from OAV and GC-O/AEDA closely resembled the original rose oil. The experiment results show that rose oxide, linalool, α-pinene, β-pinene, nonanal, heptanal citronellal, phenyl ethyl alcohol, benzyl alcohol, eugenol, methyl eugenol, β-citronellol, hexyl acetate, β-ionone, nerol, etc. are very important constituent to rose oil aroma profile.
玫瑰油价格过于昂贵，但却非常受欢迎。众所周知，花油的香气特征尚未得到深入研究。为了验证玫瑰油的香气特征，制备了合成香料混合物，然后使用电子鼻分析（ENA）结合定量描述分析（QDA）与原始玫瑰油进行比较。通过气相色谱 - 嗅觉测定法/香气提取物稀释分析（GC - O/AEDA）结合气味活性值（OAV）筛选出玫瑰油中的气味物质。ENA和QDA均表明，源自OAV和GC - O/AEDA的重组模型与原始玫瑰油非常相似。实验结果表明，氧化玫瑰、芳樟醇、α-蒎烯、β-蒎烯、壬醛、庚醛、香茅醛、苯乙醇、苯甲醇、丁香酚、甲基丁香酚、β-香茅醇、乙酸己酯、β-紫罗兰酮、橙花醇等是玫瑰油香气特征的非常重要的成分。
