<p>Coffee adulteration frequently entails the use of non-coffee materials or substandard coffee. Diverse analytical methods are typically established to enable analysts to select the most appropriate methodology for coffee authentication. This study surveys diverse approaches for detecting coffee counterfeiting, emphasizing those frequently employed, and evaluates issues related to standardization techniques by regulatory bodies through the analysis of existing review papers. Infrared (IR) spectroscopy emerges as the most referenced tool in academic research, yet chromatographic-based techniques receive greater regulatory attention. Despite substantial research on IR spectroscopy, its standardization is impeded by the complexity and variety of Fourier transform infrared (FTIR) spectra data. Furthermore, the restricted availability of standardized coffee samples hinders its adoption, while chromatographic procedures are supported by established chemical standards. Further research should concentrate on standardizing IR spectroscopy procedures for worldwide coffee authenticity rather than concentrating on feasibility studies, which most scholars already agree are achievable.</p> Graphical Abstract <p></p>
