Putrescine (PUT), spermidine (SPD) and spermine (SPM) concentrations using a UPLC method, in chilled mutton, lamb and livers 24h after slaughter were determined. PUT concentrations were quantifiable only in some samples. Mean SPD concentrations were 4–6, 13.5 and 16.8mgkg⁻¹ in the meats, sheep and lamb livers, respectively. The respective SPM concentrations were 17–25, 128 and 79mgkg⁻¹. SPD and SPM losses of about one fifth and half of the initial level, respectively, were apparent in mutton loins stored at −18°C for 6months. Significant losses of SPD and SPM were found in mutton loins stored aerobically, vacuum-packaged or in a modified atmosphere at +2°C. Boiling and stewing of mutton legs caused SPD and SPM losses of about 40% and roasting of about 60% of the initial content.
