The electronic nose (e-nose) is designed to crudely mimic the mammalian nose in that most contain sensors that non-selectively interact with odor molecules to produce some sort of signal that is then sent to a computer that uses multivariate statistics to determine patterns in the data. This pattern recognition is used to determine that one sample is similar or different from another based on headspace volatiles. There are different types of e-nose sensors including organic polymers, metal oxides, quartz crystal microbalance and even gas-chromatography (GC) or combined with mass spectroscopy (MS) can be used in a non-selective manner using chemical mass or patterns from a short GC column as an e-nose or "Z" nose. The electronic tongue reacts similarly to non-volatile compounds in a liquid. This review will concentrate on applications of e-nose and e-tongue technology for edible products and pharmaceutical uses.
电子鼻（e-nose）旨在粗略模拟哺乳动物的鼻子，因为大多数电子鼻中都包含传感器，这些传感器可以非选择性地与气味分子相互作用，产生某种信号，然后将信号发送到计算机，计算机再使用多元统计数据来确定数据中的模式。这种模式识别用于根据顶空挥发物来确定一个样本与另一个样本相似或不同。电子鼻传感器有不同的类型，包括有机聚合物、金属氧化物、石英晶体微天平，甚至气相色谱（GC）或与质谱（MS）结合使用，也可以以非选择性的方式使用化学质量或短 GC 柱的模式作为电子鼻或“Z”鼻。电子舌对液体中的非挥发性化合物的反应类似。本综述将集中讨论电子鼻和电子舌技术在食用产品和药物应用中的应用。
