by three different acyl donors at various rates. The resulting modified products were characterized by qualitative and quantitative analyses by gas chromatography, and their olfactory properties were evaluated by professional perfumers. We showed that our protocol resulted in two types of modifications of the olfactory properties. The first and most obvious effect observed was the decrease of the alcohol
我们开发了一种酶促方案,通过三种不同的酰基供体以不同的速率酰化其醇成分来改变棕榈精油的成分。所得改性产物通过气相色谱定性和定量分析表征,并由专业调香师评估其嗅觉特性。我们表明我们的协议导致嗅觉特性的两种类型的修改。观察到的第一个也是最明显的影响是酒精含量的降低,伴随着相应酯类的增加,以及它们的果味(梨,最显着)。第二个不太明显的效果是表达来自次要成分((E)-β-罗勒烯、芳樟醇、β-石竹烯和法呢烯)的音符,最初被香叶醇的甜花玫瑰气味所掩盖,70% 存在于所用的棕榈精油中,并在改性产品中出现了柑橘、绿色、辛辣和丁香的特征。这种方法可能在未来被视为调香师获得新天然成分的可持续途径。
