Title: In vitro Antioxidant Capacities of Star Fruit ( Averrhoa carambola ), an Underutilised Tropical Fruit
Abstract: Star fruit is an underutilised tropical fruit that could serves as an alternative food sources to the world. The current study was, therefore, undertaken to investigate the funct ional potentials of green and ripe star fruits by d etermining its antioxidant contents and capacities. The antioxidant capacities of star fruit were increased significantly with ri pening, except for the total ascorbic acid content. The ripe star fruit pe el contained higher total polyphenol (98.19 g TAE/1 00 g FW), total flavanol (33.31 g CAE/100 g FW) and ascorbic acid contents (1.56 g AAE/100 g FW) than green star fruit peel. Ripe star fruit peel also demonstrated stronger FRAP (1.41 M FEA/100 g FW) and DPPH (75 % inhibition) values than green star fruit peel. The antioxidant capacities of peel were greater than pulp. On the basis of results obtaine d, the ripe star fruit is a potential source of natural antioxidants owing to i ts significant antioxidant activities.
