Oxidation of fats is a leading reason for meat spoilage second only to microbial growth and it leads to a reduction of shelf life due to changes in taste, odor deterioration of texture and nutritional quality of muscle tissue. (Pereira et al, 2010). Usage of synthetic antioxidants to prevent degradation of lipids have been used for many years in the food industry but recent trends, driven by consumer concerns about synthetic additives, has shifted focus towards the usage of naturally occurring antioxidants. These naturally occurring substitutes includes extracts from herbs and spices and have shown to be extremely effective at preserving meat quality by preventing lipid oxidation.

In the present study, a citrus extract containing a mixture of bioflavinoids, was examined as a potential antioxidant to be used in food packaging and was compared against L-Tocopherol which is a known naturally occuring antioxidant.
