LOPEZ-VELASCO, Daniel Salvador et al. Antioxidant effect of bee honey on rabbit meat stored under refrigeration. CienciaUAT [online]. 2021, vol.15, n.2, pp.135-143.  Epub 14-Abr-2021. ISSN 2007-7858.  https://doi.org/10.29059/cienciauat.v15i2.1395.

Lipid oxidation deteriorates foods; therefore, synthetic antioxidants are used to decrease it. However, excess synthetic antioxidants have carcinogenic effects. Some plants such as oregano, as well as bee honey, contain natural antioxidants which are not harmful to health. No reports were found on the use of bee honey to decrease lipid oxidation in rabbit meat. The objective of this study was to assess the effect of bee honey as antioxidant on raw rabbit loin, refrigerated at 4 °C. The antioxidant activity (AA)of three types of honey was evaluated: dark, amber and clear, to be mixed with rabbit meat. Dark honey was selected for its higher antioxidant effect. 64 samples of 100 g of raw meat were prepared, 32 samples were mixed with 2 g dark honey and the other 32 were left without honey (control). The samples were stored at 4 °C and AA as well as malondialdehyde (MDA) concentrations were evaluated at 0 d, 3 d, 6 d and 9 d of storage. The AA decreased, and the MDA concentration increased (P < 0.05) with refrigeration time (changes that indicate meat spoilage). After 3 d and 6 d, the raw meat samples with honey showed higher AA (P < 0.05) and after 6 d, they showed lower MDA values (P < 0.05) compared to the control samples (these changes indicate no spoilage of meat). Dark bee honey contains high concentrations of natural antioxidants that protect ground raw rabbit loin against oxidative damage that can occur during refrigeration, therefore, its use is recommended for this purpose.
