AB Coconut is widely used as a food source in producing countries, and during consumption, the waste that is generated needs to be reduced through by-products processing to ensure environmental sustainability. This study aimed to assess the functionality of by-products (endoand mesocarp) of coconuts at early and mature stages. The aqueous and ethanolic (50 and 100% ethanol in water) extracts of coconut by-products were evaluated for the DPPH radical scavenging activity and subjected to linoleic acid-beta-carotene system assay in contrast with synthetic antioxidants. Ultrasound-producing extract of young coconut mesocarp provided the highest antioxidant activity with a lower IC50 value (117 mu g mL(-1)) than butylhydroxytoluene (BHT, 170 mu g mL(-1)). Based on the linoleic acid-beta-carotene system assay, the extract exhibited a higher antioxidant activity (1.25 x) than tertiary butylhydroquinone (TBHQ, 200 mu g mL(-1)); and comparable with butylhydroxyanisole (BHA, 250 mu g mL(-1)). Therefore, extracts of coconut by-products, particularly the young mesocarp, can be an alternative natural antioxidant.
