Interpretive Summary:

Technical Abstract: Superficial scald risk assessment assay for apples. Amounts of several components in natural apple wax can indicate risk of a peel browning disorder called superficial scald (scald). A protocol was developed that could be employed by apple producers to monitor scald risk and mitigate losses by assuring proper storage and handling practices are used. The test identifies fruit at risk months before browning occurs, therefore at-risk fruit that remains edible and of high quality can be marketed early so that the disorder is not expressed in the supply chain. The method has utility for apples produced using conventional or organic techniques.
