Abstract

The objective of this study was to examine the migration of cheese components into its polymer package by depth profiling experiment using step-scan FTIR-PAS and G2D correlation analysis. Comparison of a pure polymer film not in contact with cheese against the polymer film used to wrap cheese revealed that molecular groups related to protein in cheese adhered to the package film. The detection of fat components from cheese into the package was ambiguous because of the C-H stretch overtone at 2922 cm -1 due to functional groups related to fat and polymer. The potential of G2D analysis of infrared spectrum to enhance the resolution and interpretation and differentiate the overlapping spectral peaks was demonstrated by analysis of the depth profile spectra.
