Abstract:
'Shamouti' oranges (Citrus sinensis, Osbeck) are afflicted with a physiological blemish known as noxan which is the result of collapsed hypodermis cells in the flavedo. These blemishes reduce fruit quality and cause significant losses that threaten the future of this cultivar. Noxan incidence on 'Shamouti' orange was markedly reduced by several postharvest treatments such as individual seal-packaging, packaging fruit in plastic bags or plastic liners or even by temporarily holding the fruit in a saturated atmosphere. All these treatments raised the humidity of the atmosphere around the fruit to over 96% RH. Noxan incidence at 5 or 6°C was much lower than at 20°C. All treatments that reduced noxan also reduced weight loss and maintained the turgidity and firmness of the fruit. Fruit from an orchard prone to noxan had 44% noxan after 35 days at 20°C and 75-80% RH, but when stored for 7 days under 95-99% RH and 28 days under 75-85% RH and 20°C had only 20% noxan incidence. Fruit stored at 5°C and 90% RH had 14% noxan whereas individual seal-packaged fruit or fruit in polyethylene liners had 2-3% noxan. An hypothesis as to the nature of noxan blemishes is discussed. © 2001 Elsevier Science B.V.
