Abstract:
In the current study, influence of storage temperature (11 and 2 C) and low temperature conditioning (7 days at 16 C before cold storage at 2 C) on the bioactive compounds in 'Star Ruby' grapefruit (Citrus paradisi Macf.) were examined. Fruits stored at 11 C showed no CI; while fruits stored at 2 C showed highest CI. Conditioning treatment (CD) reduced the incidence of CI. Carotenoids and flavonoids were significantly higher after 16 weeks in fruits stored at 11 C. Low temperature storage (2 C and CD) helped to retain ascorbic acid for a longer period (12 weeks). Higher furocoumarins and taste scores along with less decay development were observed in CD fruits. Conditioning treatment can be utilized to reduce CI and to maintain taste and certain bioactive compounds of grapefruits during prolonged storage at low temperature. However, for a short storage period, 11 C temperature is more effective. © 2013 Elsevier Ltd. All rights reserved.
