High humidity (HH) packaging extended the life of different types of easily peeled citrus fruit. Thiabendazole (TBZ) and imazalil (IMZ) succeeded in maintaining low levels of decay in the HH packaged fruits. Sealed Nova and Ora mandarins after 4 weeks storage at 5 deg C followed by 1 week at 20 deg C, remained firm and lost very little weight (0.6-1% in comparison with 6.7% in the control). Sealing with the perforated film Cryovac SM60M did not reduce decay development during storage and could not substitute for fungicide treatment in mandarins. Different types of package were tested for Nova mandarins: polyethylene laminated carton boxes, groups of 10 fruits sealed in polyethylene bags and individually sealed fruits. These packaging treatments were compared to fruits stored in the standard carton container for mandarins. The fruits which received the standard packing house treatment and were stored in the standard carton had the highest decay incidence(14.4%). Decay incidence in fruits packed i
n all other treatments was 5.5% or less. Firmness was best maintained in the sealed unperforated package. Perforated packages also had an advantage in reducing weight loss and maintaining firmness in comparison with the control treatment. During prolonged storage (12 weeks) of Hadas mandarins the sealing treatment reduced acidity levels whereas in the wax treatment acidity levels increased. Reduction in acidity levels was also found in sealed Nova fruits after 5 weeks in storage.
