Abstract

Papaya (Carica papaya L. cv Eksotika) is one of the most commonly consumed tropical fruits by humans, especially Malaysians. The objective of this study was to determine the phenolic compounds and antioxidants activity in different ripening stages of papaya fruit. The fruits were harvested at five different, stages RS1, RS2, RS3, RS4, and RS5 corresponding to 12, 14, 16, 18, and 20 weeks after anthesis, respectively. Papayas fruit at five different stage of ripening were obtained from farms at Pusat Flora Cheras, JabatanPertanian and Hulu Langat Semenyih, Selangor, Malaysia. The antioxidants activity were analyzed using the total phenolic content (TPC), total flavonoid content (TFC), ferric reducing antioxidant Power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH). The analyses were conducted in triplicate and the data were subjected to statistical analysis using SPSS. The results showed significant differences (P< 0.05) were found at different stages of ripening. The total phenol content TPC, TFC, FRAP and DPPH values increased significantly (P<0.05) with the ripening process. The results showed the important role of the ripening stage in increasing the antioxidant content of papaya fruits.
