The three methylamines identified in the spectra, [trimethylamine N-oxide (TMAO), trimethylamine (TMA) and monomethylamine (MMA)], showed significant differences between non-irradiated and irradiated samples. MMA was present in all irradiated samples, and absent from non-irradiated ones. Furthermore, MMA signal intensity was well correlated with the irradiation dose applied and was stable during storage time. Therefore, MMA could be an effective indicator of irradiation in samples of salmon. eng restricted access NMR-detection of methylamine compounds in Atlantic salmon (Salmo salar) subjected to E-beam irradiation journal article
