ResumoABSTRACT Fourier transform‐infrared spectroscopy (FT‐IR) methods enable chemical discrimination of intact bacterial cells and produce complex whole‐organism biochemical fingerprints (spectra), which are reproducible and distinct for different bacteria. Numerous researchers indicate that there is great potential for using FT‐IR methods in combination with multivariate statistics (chemometrics) to detect and identify bacteria in water, culture media and foods. This article presents a review of the FT‐IR techniques, sample preparation procedures and experimental conditions used in these studies, as well as advantages, disadvantages and challenges that remain for the development of FT‐IR detection methods.
