Paper Abstract

Using Fourier Transform Infrared (FTIR) spectroscopy, we successfully examined low levels of organic contamination on aluminum coil stock surfaces. These organics were thought to have a significant impact on the flavor of beverages packaged in aluminum cans manufactured from these coils. By combining the data from the FTIR spectra and the results from professional panels trained in Profile Attribute Analysis, we were able to derive some strong analytical chemistry/sensory correlations. These types of correlations are useful in examining chemistry that impacts flavor and, in this instance, could lead to an on-line monitoring application.
