- Ginger powder effects were evaluated in cooked pork burgers after a refrigerated storage as raw meat products at 4 °C up to 7 days. Physical–chemical characteristics, fatty acids profile, lipid oxidation and antioxidant capacity of burgers were tested in control samples (only meat, C) and in two formulations containing 1% and 2% of ginger powder (G1 and G2). Ginger naturally brought yellow pigments that increased b* index of G2 burgers. Colour variations between C and G2 were also visible by human eyes as showed by ΔE indices. Ginger improved PUFAω3 and PUFAω6 percentages to the detriment of SFA with following decreases of atherogenicity and thrombogenicity indices. Antioxidants present in ginger powder reduced lipid oxidation (TBARS) and increased antioxidant capacity (FRAP, ABTS and DPPH) of burgers. Results highlighted that ginger powder could express increasing the antioxidant capacity and reducing lipid oxidation of burgers with the final income of healthier products than the control ones.
