This narrative review examines the complex relationship that exists between the presence of specific configurations of volatile organic compounds (VOCs) in food and drink products and multisensory flavour perception. Advances in gas chromatography technology and mass spectrometry data analysis mean that it is easier than ever before to identify the unique chemical profile of a particular food or beverage item. Importantly, however, there is simply no one-to-one mapping between the presence of specific VOCs and the flavours that are perceived by the consumer. While the profile of VOCs in a particular product undoubtedly does tightly constrain the space of possible flavour experiences that a taster is likely to have, the gustatory and trigeminal components (i.e., sapid elements) in foods and beverages can also play a significant role in determining the actual flavour experience. Genetic differences add further variation to the range of multisensory flavour experiences that may be elicited by a given configuration of VOCs, while an individual's prior tasting history has been shown to determine congruency relations (between olfaction and gustation) that, in turn, modulate the degree of oral referral, and ultimately flavour pleasantness, in the case of familiar foods and beverages.
这篇叙述性综述探讨了食品和饮料产品中挥发性有机化合物(VOCs)的特定组成与多感官风味感知之间存在的复杂关系。气相色谱技术和质谱数据分析的进展意味着,识别特定食品或饮料的独特化学特征比以往任何时候都更容易。然而,重要的是,特定VOCs的存在与消费者所感知的风味之间并没有简单的一一对应关系。虽然特定产品中VOCs的组成无疑会严格限制品尝者可能拥有的风味体验空间,但食品和饮料中的味觉和三叉神经成分(即风味元素)在决定实际风味体验方面也可能发挥重要作用。基因差异进一步增加了由给定的VOCs组成所引发的多感官风味体验范围的变化,而个人过去的品尝经历已被证明可以决定(嗅觉和味觉之间的)一致性关系,进而在熟悉的食品和饮料中调节口腔转移程度,并最终影响风味的愉悦度。
