The manufacture of counterfeit goods is one of the world's largest underground businesses and is rapidly growing. Counterfeits can lead not only to the loss of profit for honest producers but also have a negative impact on consumers who pay excessive prices for poor quality goods that may result in health or safety problems. The perfume industry is constantly vulnerable to counterfeits, particularly in the fast developing market of "smell-alike" designer-inspired perfumes because these prompt the identification of the methods that classify their quality. In this paper, the application of proton nuclear magnetic resonance (H NMR) spectroscopy is employed for the first time to authenticate perfumery products. The molecular composition of several types of authentic brand fragrances for women was compared with cheap inspired equivalents and fakes. Our approach offers the prospect of a fast and simple method for detecting counterfeit perfumes using H NMR spectroscopy.
假冒商品的制造是世界上最大的地下产业之一，而且其规模还在迅速扩大。假冒商品不仅会使诚实的生产商损失利润，而且还会对消费者造成负面影响，因为消费者会为质量差但价格过高的商品支付过高的价格，而这些商品可能会导致健康或安全问题。香水行业一直容易受到假冒商品的影响，特别是在“仿香”设计灵感香水这个快速发展的市场中，因为这些香水促使人们确定了鉴定其质量的方法。在本文中，首次应用质子核磁共振（H NMR）光谱法对香水产品进行真伪鉴定。将几种类型的正宗女性品牌香水与廉价的灵感型仿制品和假冒品进行了分子成分比较。我们的方法为使用 H NMR 光谱法快速简单地检测假冒香水提供了前景。
