Abstract

We have developed an infrared spectroscopic technique (Fourier transform infrared spectroscopy with attenuated total reflectance system) for the non‐invasive measurement of saturated and unsaturated fatty acid compositions in human oral mucosa, and applied it to tissue from three nationalities: Iranian, Vietnamese, and Indonesian. The second derivative infrared spectra of the mucosal tissues were additionally analyzed with the partial least squares multivariate regression analysis method. Almost all fatty acid compositions of oral mucosa could be well predicted with differences between predicted (FTIR‐ATR) and measured values (GC‐MS). Consequently this technique may provide a great advancement to fatty acid analysis in the fields of food science, preventive medicine and epidemiology.
