In the present work we investigated the chemical changes undergone by enzyme-oxidized lauryl gallate (LG, dodecyl 3,4,5,-trihydroxybenzoate) by using Fourier transform infrared (FTIR) spectroscopy, and an oxidation mechanism is proposed from the results. The FTIR analysis revealed that enzyme-modified gallates consist mainly on open-ring acid products, while the hydrocarbon chains remained unaltered after oxidation |
