Abstract:

The present work aimed to evaluate some chemical and antioxidant properties of lemon and orange peels (primary byproducts discarded as waste) to identify their potential use as value-added functional ingredients. Ethanolic or methanolic extracts of the dried peels (microwave or air oven drying methods) were conducted. Proximate chemical composition, vitamin C, phenolic, flavonoids contents, also radical scavenging activities (DPPH), Trolox equivalent antiradical capacity (ABTS) and β-carotene assays for antioxidant activity were determined. All analyzed samples showed that citrus peels are cheap and good source for natural bioactive compounds with high contents and have good antioxidant activities.


Keywords: Citrus byproducts, Lemon peels,Orange peels,   Antioxidant properties, Phenolic compounds.
