Postharvest UV-B treatment of Peach Fruits

Claudia Scattino visited Prof. Monika Schreiner in Germany (20 days in April 2013)

The aim of this work was to characterize peach and nectarine cultivars by their different polyphenolic profile and investigate the effects of post-harvest UV-B treatments on the polyphenol content of peach fruit skin.

Several analyses have been carried out on fruits from 3 different cultivars.

Different phenolic profiles were found for the 3 cultivars analysed, in particular Hydroxycinnamates, Flavan 3-ols, Flavonols, Anthocyanins contents were determined. The UV-B post-harvest treatment induced different effects depending on the phenolic substance considered and the length of the irradiation treatment.
