Influence of postharvest curing on marsh grapefruit quality during long-term storage. Citrus fruit can incur rind damage due to chilling injury (CI) if stored for extended periods below recommended temperatures.High-temperature pre-storage conditioning or curing treatments have been successful in preventing or reducing CI in many horticultural crops.Marsh grapefruit fruit (Citrus paradisi Macf.) was cured (24 or 48 h at 37 °C, 90% R.H.) previous storing to determine its effect o­n chilling injury symptoms o­n the peel, weight loss and internal quality.Cured and not cured grapefruit harvested in Concordia (Argentina) were stored during two months at 2 °C or 9 °C.

Fruit quality was evaluated every 15 days and after shelf life (7 days, 20 °C).CI was influenced by treatments, temperature and storage duration.Pitting was observed in grapefruit kept at 2 °C after 30-45 days.The severity of this damage increased according to the storage period.Fruits stored at 9 °C did not show CI.Slight CI was observed in fruits cured after 60 days at 2 °C.Curing increased weight loss and ripening index.Ethanol and acetaldehyde content in juice increased with storage.Volatile levels were higher in fruits no cured and stored at 2 °C.
