“…This method does not only minimise issues with reproducibility it also allows for a rapid analysis. As with any screening technique, ATR also has its limitations, caused by the optical contact between the sample and the ATR crystal (Lindenberg et al, 2012). This is of particular concern when solid samples are analysed, and in order to overcome this issue the accessories have devices that clamp the sample to the crystal surface and apply pressure (Lindenberg et al, 2012).…”

The increasing demand for food and the globalisation of the supply chain, have resulted in a rise in food fraud, and recent high profile cases, such as the Chinese milk scandal in 2008 and the EU horsemeat scandal in 2013 have emphasised the vulnerability of the food supply system to adulteration and authenticity frauds. Fourier Transform Infrared (FTIR) spectroscopy is routinely used in cases of suspected food fraud as it offers a rapid, easy and reliable detection method for these investigations. In this review we first present a brief summary of the concepts of food adulteration and authenticity as well as a discussion of the current legislation regarding these crimes. Thereafter, we give an extensive overview of FTIR as an analytical technique and the different foods where FTIR analysis has been employed for food fraud investigations as well as the subsequent multivariate data analysis have been applied successfully to investigate case of adulteration or authenticity. Finally, we give a critical discussion of the applications and limitations of FTIR, either as a standalone technique or incorporated in a test battery, in the fight against food fraud.
