title: Influence of type of amphora on physico-chemical properties and antioxidant capacity of 'Falanghina' white wines.
abstract: The present research was aimed to evaluate the effects of ageing and type of container on physico-chemical indices and on antioxidant compounds of 'Falanghina' wines. Wines were stored for 12months in raw, glazed, and engobe amphorae, and in stainless steel tanks. Lactic, acetic, citric, succinic, and hydroxycinnamoyl tartaric acids, and the antioxidant capacity (DPPH assay) were not affected by the type of container for the duration of the ageing. Flavonoids decreased by about 85% in all the containers. The concentrations of flavans reactive with vanilline were reduced by 100% in raw and glazed amphorae, 23% in engobe amphorae, and 59% in stainless steel tanks. The hydroxycinnamoyl tartaric acids decreased by about 11% in raw and engobe amphorae and by ∼22% in glazed amphorae and in stainless steel tanks. During the whole ageing time, the decrease of the antioxidant capacity ranged from 28% (raw amphorae) to 43% (stainless steel tanks).
