摘要

Past cases have shown that the faking of 58°Kinmen Kaoliang Liquor (58° KKL), a type of sorghum liquor, is usually dominated by adulteration, in two forms concerning the use of bottle labels: 1) recycling old bottles with authentic bottle labels and 2) sticking fake bottle labels on bottles. A complete and systematic authentication procedure of 58°KKL usually requires analyses to be performed on the bottle cap, bottle label, and liquor. However, this study focuses on analytical methods for the identification of bottle label, with physical identification methods involving ultraviolet (UV) light source, digital microscope, video spectral comparator (VSC), and with chemical identification methods involving X-ray fluorescence spectrometer (XRF), scanning electron microscope/energy dispersive X-ray spectroscopy (SEM/EDS). By using these complementary and comparative analytical methods, a total of 12 features with discriminative value were obtained, based on which an analytical strategy for the authentication of 58° KKL bottle label was established to improve the credibility of evidence.
