title: Functional properties and stability of spray-dried pigments from Bordo grape (Vitis labrusca) winemaking pomace.
abstract: The stability of anthocyanin and phenolic compounds, the antioxidant capacity, the antimicrobial activity and the capacity to inhibit arginase from Leishmania were evaluated in spray-dried powders from Bordo grape winemaking pomace extract. The pigments were produced using maltodextrin as the carrier agent at concentrations varying from 10% to 30% and air entrance temperatures varying from 130 to 170°C. A sample of freeze-dried extract without the carrier was also evaluated. The anthocyanins in the spray-dried samples showed good stability during storage, better than the freeze-dried and liquid extracts. The samples were capable of inhibiting the growth of Staphylococcus aureus and Listeria monocytogenes and showed high inhibitory capacity against the enzyme arginase from Leishmania. These results provide evidence that Bordo grapes from the winemaking process have the potential to be used as natural pigments with functional properties.
