Abstract

The impact of ozone concentration and ozonisation time on the selected chemical, physical and microbiological properties of Rapanui tomatoes was investigated. Tomatoes were exposed to gaseous ozone at concentrations of 0.9 and 2.5 mg L −1 (c 1 , c 2 ) for 30 and 120 min (t 1 , t 2 ), and stored for up to 15 days at a temperature of 12 ± 1 °C. The following parameters were evaluated: titratable acidity, total soluble solids, total phenolic and flavonoid contents, lycopene, total carotenoids, vitamin C, total antioxidant activity, colour L* a* b* and firmness. Ozonated fruit had higher levels of total soluble solids and higher levels of titratable acidity during and after storage. Exposure of tomatoes to a cooling atmosphere, applying recommended ozonisation process parameters, efficiently inactivated microorganisms that are present on the surface and reduced fruit weight loss, while retaining their firmness and stable colour.
