The food products may attract unscrupulous vendors to dilute it with inexpensive alternative food sources to achieve more profit. The risk of high value food adulteration with cheaper substitutes has reached an alarming stage in recent years. Commonly available detection methods for food adulteration are costly, time consuming and requires high degree of technical expertise. However, a rapid and suitable detection method for possible adulterant is being evolved to tackle the aforesaid issues. In recent years, electronic nose (e-nose) system is being evolved for falsification detection of food products with reliable and rapid way. E-nose has the ability to artificially perceive aroma and distinguish them. The use of chemometric analysis together with gas sensor arrays have shown to be a significant procedure for quality monitoring in food. E-nose techniques with numerous provisions are reliable and favourable for food industry in food fraud detection. In the present review, the contributions of gas sensor based e-nose system are discussed extensively with a view to ascertain the adulteration of food products.
食品可能会吸引无良商贩用廉价的替代食物来源对其进行稀释，以获取更多利润。近年来，用更便宜的替代品掺假高价值食品的风险已达到令人担忧的程度。常用的食品掺假检测方法成本高、耗时且需要高度的技术专长。然而，一种针对可能的掺假物的快速且合适的检测方法正在不断发展，以解决上述问题。近年来，电子鼻（e-nose）系统正在不断发展，以可靠且快速的方式对食品进行掺假检测。电子鼻有能力人工感知香气并区分它们。化学计量分析与气体传感器阵列的结合已被证明是食品质量监测的一个重要过程。具有众多功能的电子鼻技术在食品欺诈检测方面对食品行业来说是可靠且有利的。在本综述中，基于气体传感器的电子鼻系统的贡献被广泛讨论，以确定食品的掺假情况。
