Control of Lipid Oxidation in Muscle Food                      373
  VetBooks.ir  According to Park et al. (2012), the antioxidant films improved the effi-


            cacy of vacuum packaging and stabilized raw beef patties against oxida-
            tion.  The  antioxidant  property  of  prepared  film  containing  3%  eugenol
            was similar to that of the film containing 0.3% eugenol, which suggests
            that eugenol is a strong antioxidant and 0.3% concentration was sufficient
            to completely retard lipid oxidation in beef patties. Contini et al. (2014)
            also showed that antioxidant active packaging with citrus extract is effec-
            tive in reducing the lipid oxidation of cooked turkey meat during storage
            and in maintaining its sensory characteristics, particularly tenderness and
            overall acceptability. In line with this, lowest lipid oxidation was observed
            for  samples  packed  with  chitosan-incorporated  bags,  which  might  be
            helpful to limit lipid oxidation of the drumsticks during the storage period
            (Soysal et al., 2015). Barbosa-Pereira et al. (2014) observed a reduction in
            lipid oxidation by up to 80% in beef wrapped in films coated with natural
            extracts obtained from a brewery residual waste, while Tornuk et al. (2015)
            suggested that the active nanocomposite packaging had potential to extend
            shelf life of fresh beef by reducing E. coli O157:H7 numbers and retarding
            the meat discoloration.
               Finally,  active  packaging  can  be  used  in  combination  with  other
            processing treatments to extend food shelf life. High pressure processing
            has shown to be an effective technology to improve safety of meat and meat
            products (Marcos et al., 2008; Realini et al., 2011). However, high pres-
            sure processing may accelerate meat oxidation (Ma et al., 2007; McArdle
            et al., 2011, 2013). In line with this, Bolumar et al. (2011) observed that
            the antioxidant compounds from the antioxidant active package (rosemary
            extract) suppress the oxidation in both the surface part and the inner part
            of chicken meat patties and prevent formation of secondary lipid oxidation
            products. So, the antioxidant active packaging was able to delay the oxida-
            tion induced by high pressure processing and consequently extend the shelf
            life of chicken patties.



            9.6 CONCLUSION

            The active antioxidant packaging is a promising emerging technology to
            avoid the undesirable effects of lipid oxidation during meat storage. This
            solution provides several advantages compared to direct addition of anti-
            oxidants, such as lower amounts of active substances required, localization
            of the antioxidant activity to the surface, progressive migration from film to
            the food matrix that provides long-term antioxidant effects, and elimination
