AbstractThe effect of the addition of natural antioxidants (tea, chestnut and grape seed extracts) on physico-chemical and oxidative stability of refrigerated stored pig pâtés was studied. This effect was compared with that showed by the synthetic antioxidant BHT. Pâté samples were analysed at 0, 4, 8 and 24 weeks of refrigerated storage (4 °C). Colour parameters were affected by storage period and antioxidant extract. Samples with CHE and GRA extracts showed lower total colour difference between 0 and 24 weeks. The amount of TBARS gradually increased during refrigerated storage with the exception of pâtés that have CHE extract in composition. At the sampling end point, the lower TBARS values were obtained in samples with TEA and GRA extracts. Finally, the evolution of volatile compounds during storage showed an increase in the lipid-derived volatile values after refrigerated storage, since samples with TEA and GRA extract showed the lowest values.
