Effects of 'Semperfresh' coating on postharvest life, internal atmosphere modification and quality maintenance of Granny Smith apples.

The effects of coating DPA (diphenylamine)- and non-DPA-treated Granny Smith fruits of 2 different maturities (early and late season) with 0.75 or 1.5% Semperfresh (a sucrose ester preparation) on their postharvest life, quality attributes, internal atmospheres and on the incidence of some physiological disorders were investigated after storage at 0 deg C for 4 or 5 months, and during subsequent ripening at 20 deg . Coating early or late harvested fruits with Semperfresh delayed ripening somewhat, as indicated by the slightly better retention of green skin colour and flesh firmness, and the reduced respiration and ethylene production rates that were observed upon transferring the fruits to 20 deg . Internal CO2 and ethylene levels increased and internal O2 levels decreased in Semperfresh-coated fruits during storage at 0 deg . No significant differences among treatments were noted in bitter pit incidence. DPA was necessary for controlling superficial scald. Coating with Semperfresh did not reduce the development of superficial scald, and in early harvested fruits it aggravated the incidence of the disorders in both DPA- and non-DPA-treated fruits.
