The trans fatty acids (TFA) quantification is required due to its harm of human health, regular consumption can increase the risk of diseases. To reduce the intake, consumers must be informed about the negative impact on their health and the TFA content labelled. Countries as the US, Canada, and Denmark impose a maximum usage of TFA in products for a consumer higher safety. The GC and IR methods are commonly used for TFA quantification, and through this review, it was highlighted the importance and the advantages of IR procedure. FT-IR is a non-invasive, rapid and powerful technique superior to other techniques in noise-signal ratio, spectral resolution, samples treatment, and detection sensitivity. The present work addresses a comprehensive review of different IR techniques, a comparison, and the election of the most efficient one. ATR-FT-IR methods turned out to be easier and faster for the trans fatty acids quantification at its specific region (991-945 cm-1). One of the main approaches of this review is the rapidity of IR methods, the analysis can be executed directly on the fat without the need for specific preparation of samples.
