This paper proposes postharvest ozone fumigation (as a method) to control microorganisms and evaluate
the effect on polyphenols, anthocyanins, carotenoids and cell wall enzymes during the grape dehydration
for wine production. Pignola grapes were ozone-treated (1.5 g/h) for 18 h (A = shock treatment), then
dehydrated or ozone-treated (1.5 g/h) for 18 h and at 0.5 g/h for 4 h each day (B = long-term treatment)
during dehydration
