APPLICATION OF PHYTOCHEMICAL COATINGS TO ENHANCE SHELF LIFE AND FREE RADICAL SCAVENGING ACTIVITY OF HARVESTED TOMATO FRUIT

F.M. Salas, R.A. Salas, V.N. Pole, M.A. Quevedo
This research evaluated the shelf life and free radical scavenging activity (FRSA) of tomato ‘Diamante Max’ harvested at different stages of maturity, coated with aqueous, ethanol and acetic acid extracts of cat’s whisker (Orthosiphon aristatus (Blume) Miq.), turmeric (Curcuma longa L.), hagimit (Ficus minahasse Miq.), and starfruit (Averrhoa carambola L.), and stored at ambient (24-32°C, 65-88% RH). The aqueous hagimit extract (AQHE) best enhanced the shelf-life of mature-green fruit (97 days), ethanolic hagimit extract (ETHE) for breaker fruit (83 days), and acetic acid starfruit extract (AASE) for red fruit (31 days). FRSA, measure by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method, was highest in red fruit. The phytochemical extracts increased FRSA in mature green and breaker fruit during storage.
