The Recovery of Waste Cooking Oil using Natural Antioxidants from Mangosteen Peel

Abstrak

Waste cooking oil can cause several health risks, such as carcinoma, because it contains peroxide compounds and fatty acids that are degraded due to auto-oxidation caused by reheating the oil over and over again. Peroxide Number: The higher the peroxide number, the greater the damage to the waste cooking oil. The number shows the level of oxidation, with the safe limit as of <10 meq/kg. Acid Number: Shows the amount of fatty acid; the higher the amount means the lower the quality of oil.
