The effects of prestorage heat treatment on poststorage quality of apples (Malus domestica B.) were investigated in 'Fuji' fruits, a long-storable late season cultivar. The major benefit was a decrease in the rate of flesh softening at a storage temp. of 38 deg C for 4 d. High temp. treatment (48 deg C for 4 h) maintained fruit quality but increased apple disorders during storage. The high temp. treatment did not cause internal breakdown or core browning during 6 months' storage. The CO2 concn in PE film bags was decreased by treatment at 38 deg C for 4 d or 48 deg C for 4 h, while ethylene production was not affected by either treatment. Soluble solids content was not affected by heat treatment, and titratable acidity was reduced by both heat treatments compared to the control. The optimum conditions for prestorage heat treatment for apple storage were 4 d at 38 deg C.
