The study evaluated the effects of different levels of olive leaf extract on mutton meatballs, finding that 0.3% extract is suitable as a natural antioxidant source. Storage period negatively impacted color, flavor, and acceptability of the meatballs.
This study was aimed to evaluate the effects of using different levels of olive (Olea europaea) leaf extract on fresh and preserved mutton meatballs. Meatballs were divided into four different groups and treated as T0 (0), T1 (0.1), T2 (0.2) and T3 (0.3%), respectively based on olive leaf extract supplementation. Days of intervals of experiment were 0, 5, 10 days. Samples were preserved at 4C for up to 10 days. Different types of analysis such as, sensory (color, flavor, juiciness and overall acceptability), proximate composition (CP %), physicochemical (pH), biochemical (POV, FFA and TBARS) and microbiological (TVC, TCC and TYMC) were determined. Color, flavor and acceptability reduced significantly (p < 0.05) with the increase of the storage periods. Values of the studied quality parameters in all the treatment groups differed significantly (p < 0.05). Based on our findings 0.3% olive leaf extract is found suitable to add in mutton meatballs as a source of natural antioxidant.
