Freezing is one of the most important preservation methods for meat and meat products since compared with other methods, it leads to a minimal loss of quality during long-term storage.Therefore, freezing rate and frozen storage temperature influence the structure of frozen meat and its sensory qualities.Oxidative reactions in meat are the most important factor in quality losses, including flavour, texture, nutritive value and colour.Muscle cells contain high amounts of proteins, which can also be affected by oxidative reactions.Therefore, this study investigated the effects of different freezing temperatures and duration of frozen storage on lipid and protein oxidation in chicken breast and leg meat.
