Abstract
The optimal conditions and duration of storage of fresh produce has been the subject of ongoing effort for many decades.
In practice, variable fruit quality at harvest and deviation from the optimal temperature can cause substantial losses.
It is therefore of interest to use computational tools to account for the reduction of quality considering both the initial quality and the time-temperature variables.
Supervised machine learning models require large data sets.
To that end, 2204 clusters of grapes were scored for quality features at harvest, packed in standard commercial format, and examined every 3 weeks during 3 months of cold storage.
Grapes could be effectively stored free of decay for 3 weeks at 6°C, 6 weeks at 3°C, and 9 weeks at 0°C. The level of decay at harvest in 9 vineyards was associated with the level of decay after 9 weeks of storage suggesting that this is an important predictor of storage quality.
The data presented in this research will assist in taking into account the effects of deviations from optimal storage temperature and the potential outcomes of storage of grapes from vineyards suffering from high sour rot incidence.
