Abstract
The study was conducted to determine the effect of storage time on the free radical scavenging activity (FRSA) of mature red tomatoes with hagimit extracts, to investigate the effect of timing of application of hagimit extract on the FRSA of the mature red tomatoes, and to evaluate the maximum/optimum FRSA of the mature red tomatoes coated with hagimit extracts. Coating was done on the 4th, 6th and 8th day after harvest of the tomato fruits and analyzed for FRSA. Results show that free radical scavenging activity of untreated tomato fruit drastically reduced after 6 days of storage. However, when the tomato fruits were coated with polar hagimit extracts, the free radical scavenging activity was sustained until 12 days of storage with only gradual decrease until the end of its shelf-life. Application of hagimit extracts 4, 6, and 8 days after harvest of the tomato fruits showed similar preservation of the fruits’ free radical scavenging activity although fruits coated 4 days after harvest were of shorter shelf-life. Moreover, the optimum free radical scavenging activities of tomato fruits coated with aqueous, ethanolic, acetic acid extracts were 340.54, 349.01, 348.88 μmolTE/100g, respectively.
