Postharvest heat treatment as a possible means of reducing superficial scald of apples.

A pre-storage heat treatment of 38 deg C for 4 d applied to apple cv. Granny Smith fruits before standard storage in air at 0 deg inhibited the development of superficial scald. Apples stored for 3 months after heat treatment had superficial scald levels similar to those of apples dipped in diphenylamine (DPA), whereas all control apples had scald. This inhibitory effect was no longer apparent after 5 months of storage. The heat treatment inhibited the accumulation of alpha -farnesene and conjugated trienes in apple cuticles while DPA inhibited only alpha -farnesene oxidation. Heat-treated apples also had lower polyphenoloxidase activity in the peel than untreated apples. This treatment may be a substitute for chemical treatments for short-term storage of scald-susceptible apple cultivars.
