In the last two decades, scientific methodologies for the prediction of the design, performance and classification of fragrance mixtures have been developed at the Laboratory of Separation and Reaction Engineering. This review intends to give an overview of such developments. It all started with the question: what do we smell? The Perfumery Ternary Diagram enables us to determine the dominant odor for each perfume composition. Evaporation and 1D diffusion model is analyzed based on vapor-liquid equilibrium and Fick's law for diffusion giving access to perfume performance parameters. The effect of matrix and skin is addressed and the trail of perfumes analyzed. Classification of perfumes with the perfumery radar is discussed. The methodology is extended to flavor and taste engineering. Finally, future research directions are suggested.
在过去的二十年中，分离与反应工程实验室已经开发出了用于预测香精混合物的设计、性能和分类的科学方法。本文旨在对此类进展进行综述。这一切都始于一个问题：我们闻到了什么？调香三元图使我们能够确定每种香水成分的主要气味。基于汽液平衡和扩散的菲克定律对蒸发和一维扩散模型进行分析，从而获得香水性能参数。讨论了基质和皮肤的影响以及香水的踪迹。用调香雷达对香水进行分类。该方法扩展到了风味和口感工程。最后，提出了未来的研究方向。
