Abstract
This work examined the utilization of potato and tomato peels, as antioxidants natural source for retarding lipid oxidation in slices of lamb meat (Awassi). Meat slices treated with potato peel extract (PPE) and tomato peel extract (TPE) in two different concentrations (0.1%, 0.5%). Then, lipid peroxidation and pH was determined in samples at three different periods with 5 days. We found low levels of peroxide value in samples due to treatment with natural antioxidants. Potato peel extracts were less effective than tomato peel extracts due to lower phenolic content 96.66 mg of Gallic acid /100 g in potato peel extract vs 130.53 mg of Gallic acid /100 g. We suggest using tomato peel extract for retarding lipid peroxidation in chilled storage of lamb meat.
