Synthetic antioxidants have been successfully used to prevent lipid oxidation in chicken meat. However, increasing concerns over the safety of synthetic food additives have resulted in a trend towards ‘‘natural products’’. As a result, the industry faces a challenge to find effective antioxidants from natural sources to prevent deterioration in meat and meat products during processing and storage (Brannan, 2009). Among natural antioxidant sources, rosemary(Rosmarinus officinalis L.), a woody aromatic herb that is native to the Mediterranean countries, has recently been authorized by the European Union under Directive 95/2/EC and assigned E-392 as its E number (European Union Directives 2010/67/EU and 2010/69/EU) for use in meat product preservation. The addition of rosemary extract to poultry products has been shown to be effective in retarding lipid oxidation, and previous studies in chicken sausages (Liu, Tsau, Lin, Jan, & Tan, 2009) and patties (Naveena et al., 2013) have pointed to the protective effect of rosemary extract (500–1500 ppm) and leaves (22.5–130 ppm) in inhibiting lipid oxidation.
