Nutritional labels often under report trans-fat content. Due to the health problems associated with consumption of trans-fats, efforts must be made to ensure careful monitoring and enforcement of current guidelines. Recent FDA press releases indicate that trans-fat will be removed from the GRAS substances list in the near future. If such regulation were to be enacted, it would effectively act as a ban on all ¬trans-fats in food. The objective of this study was to isolate and quantify trans-fat content in a variety of local food products reporting some level of trans-fat in the product and approximate the prevalence of misrepresentation of trans-fat levels across several types of foods. Isolation of trans-fatty acids from locally obtained food products was achieved using AOAC Official Method 2000.10 and analysis was performed using the Cary 630 portable FTIR. A standard curve was constructed using trielaidin at varying concentrations. Isolated trans-fats from 40 food products were analyzed; three replicates were run for each product. Spectral data examined using partial least squares regression (PLSR) showed very good correlations (R²; > 0.998) for models produced using both spectrometers. Portable ATR-MIR spectrometers allow for increased flexibility in set up and use while retaining the traditional benefits of FTIR spectroscopy such as rapid throughput, high sensitivity, and large amounts of data per second, making it ideal for regulatory applications and well suited to quality control applications
