Postharvest Heat Treatments of Horticultural Crops

The effect of antifungal hot-water treatments on papaya postharvest quality and activity of pectinmethylesterase and polygalacturonase

“…Heat treatments have been shown to be effective as a non-chemical mean of improving postharvest quality of a range of horticultural products. They are usually applied as hot water dips, vapor heat, or hot-air treatments (Lurie 1998). They may affect ripening and protect against physiological disorders (Klein and Lurie 1992), and have been used as an effective alternative treatment for decay control (Cantwell and Nie 1996).…”

Abiotic Stress in Harvested Fruits and Vegetables

“…Use of heat treatments has become popular for disinfestation and disinfection of fruits and vegetables (Lurie, 1998). Appropriately applied levels of heat treatment can also induce temperature tolerance to both high and low temperatures (Lurie, 1998). However, when excessively harsh heat treatments are applied, heat-induced damage can occur.…”

“…Hence, it is very difficult to design effective treatments to achieve the resistance required for any or all abiotic stresses that a fruit or vegetable may encounter during harvest, handling, storage and distribution. Hot or warm water treatments have been shown to minimize cutting induced injuries in fresh-cut products (Lurie, 1998). Such treatments may also be used to control chilling injury via induction of heat shock proteins (Collins et al, 1995;Sabehat et al, 1996).…”

“…While there are visible (surface pitting, internal browning) and textural (accelerated softening and development of mealiness) changes often associated with chilling injury (Wang, 1993;Saltveit, 2003), flavour generation capacity has been shown to be a sensitive early indicator of chilling stress effects (Maul et al, 2000). Use of heat treatments has become popular for disinfestation and disinfection of fruits and vegetables (Lurie, 1998). Appropriately applied levels of heat treatment can also induce temperature tolerance to both high and low temperatures (Lurie, 1998).…”

Combined Effects of Fungicides and Thermotherapy on Post-Harvest Quality of Horticultural Commodities

“…The first experiment cited in the literature was the postharvest use of hot water and hot sodium hydroxide solutions to control citrus moulds. Subsequently, the use of the thermotherapy was also widely applied against parasites of horticultural commodities (Barkai-Golan & Phillips, 1991;Lurie, 1998;Schirra et al, 2000a;Shellie & Robert, 2000;Fallik, 2004;Fallik & Lurie, 2007).…”
