Investigating the effect of antioxidant extract from orange peel on lipids oxidation

This research involved investigation of the extraction yield and antioxidant property of orange peel on lipid oxidation. Orange peel was oven dried, grinded to powder and extraction procedure carried out using methanol as solvent in a soxhlet extractor. The effects of time and temperature on the extraction process were considered and results obtained showed an optimum extraction temperature and time of 50ºC and 120 minutes respectively. X-ray fluorescence analysis of the orange peel extract showed that potassium and calcium are the major elements by percentag mposition of 55.5 and 32.65 respectively. In studying the effects of oran eel extract on the melon oil sample, peroxide, free fatty acid and pH analysis were carried out for a period of 60 day. The result obtained confirmed the of ability orange peel extract as antioxidant agent
