Abstract:
Lamb meat hygiene and oxidation were considered in two groups of animals fed a diet with and without a mix of dill (Aneto graveolens L.), cinnamon bark (Cinnamomum Zeylanicum Blume) and eucalyptus (Eucalyptus globulus Labill.) essential oils. After 7 days of storage, a significant difference was observed on the Total Viable Count (TVC) of the meat surface (6.58 and 7.03 Log CFU/g for the meat from treated and untreated group, respectively), but not on the Enterobacteriaceae count (2.54 and 2.84 Log CFU/g). The effect on red meat color was evident after 7 days (redness values, 11.51 and 12.96 in untreated and treated group, respectively). The antioxidant effect of the essential oil mix was shown by the DPPH and ABTS assays, which revealed a higher antioxidant activity of the meat, and by the TBARs values, with lower levels observed in the meat of the supplemented group.
