Abstract:
... Hot-water rinsing (3 or 4min) and dipping (15, 20 or 25s) at a range of incubation temperatures was applied to apples (cv. ‘Ingrid Marie’ and ‘Pinova’) naturally infected with a range of North West European storage-rot fungi. Significant reductions in the incidence of fruit rot were achieved by incubation periods of 3min at 50–54°C (dipping) and 20 or 25s at 55°C (rinsing), followed by up to 100d ...

Abstract:
... Sweet pepper (Capsicum annuum L.) is one of the most important fruit crops in Israel and other Mediterranean countries. Various pepper-importing countries, such as the USA, demand quarantine security protocols to diminish the risk of accidental introduction of the Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) on imported fruit. Effective quarantine treatment protocols must combin ...

Abstract:
... Film-forming dispersions (FFD) were prepared with 1% high molecular weight chitosan and 3% lemon essential oil and were submitted to two different homogenization treatments. The particle size and viscosity of the FFD were evaluated and stand-alone coatings were characterized in terms of water vapour permeability (WVP) and antimicrobial activity. The FFD were applied to cold-stored strawberries, cv ...

Abstract:
... The effect of 1-methylcyclopropene (1-MCP) on senescence and quality maintenance of green bell pepper fruit was investigated. To explore the optimum concentration of 1-MCP to delay senescence, pepper fruit were treated with 0.5, 1.0 or 1.5μLL⁻¹ 1-MCP and then stored for 10d at 20°C. The results showed that the application of 1-MCP at 1.0μLL⁻¹ was most effective in delaying senescence, man ...

Abstract:
... The mechanisms of action of Cu²⁺ in improving the longevity of cut flowers and foliage have not been elucidated. Possible antimicrobial action of Cu²⁺ against stem end and vase solution colonising bacteria was investigated using Cu²⁺ treatments optimised for cut Acacia holosericea A. Cunn. ex G. Don foliage stems. These treatments were a 5h pulse with 2.2mM Cu²⁺ or a 0.5mM Cu²⁺ vase solution versu ...

Rosa; models; prediction; reaction kinetics; storage temperature; storage time; vase life
Abstract:
... The objective of the present paper was to examine the hypothesis that the time–temperature sum built up during storage and transport at constant as well as stepwise changing temperatures is a good predictor of the remaining vase life of cut roses. Theoretical calculations and graphing of functions showed that the time–temperature sum closely approximated the more common approach to quality loss, i ...

Abstract:
... Bananas (Musa spp.) are highly perishable fruit of notable economic and nutritional relevance. Because the identification of proteins involved in metabolic pathways could help to extend green-life and improve the quality of the fruit, this study aimed to compare the proteins of banana pulp at the pre-climacteric and climacteric stages. The use of two-dimensional fluorescence difference gel electro ...

Abstract:
... The volatile compounds of three commercial Japanese plum cultivars (‘Pioneer’, ‘Laetitia’ and ‘Angeleno’) were determined for a seven week period including samples from three different maturity stages (immature, harvest and tree-ripe) over two fruiting seasons. At commercial harvest, samples were also cold-stored and ripened, mimicking the South African export protocols. HS-SPME was used for extra ...
