Abstract

The aim of this study was to analyze the contents of ascorbic acid, phenolics, flavonoids, carotenoids, lycopene, β-carotene and their antioxidant activities in the different maturity stages of tomatoes. The results showed that tomatoes in pink and red stages exhibited higher contents of ascorbic acid concomitant with the correspondent higher hydrophilic antioxidant activities. The contents of phenolics, carotenoids and lycopene were increasing till the red maturity stage. Significant correlation between the DPPH radical scavenging activity and carotenoids, however lycopene was effective in its lowest concentration. The β-carotene was intensively synthesized between the green and breaker maturity stages, and higher correlated with the FRAP capacity. These findings indicated that tomatoes can be considered as natural sources of bioactive compounds regardless of the maturity stages, while tomatoes in pink and red maturity stages has higher nutritional value and antioxidant activity.
