3.2. Effects of HIPEF treatment conditions on antioxidant
capacities of orange juice and gazpacho
Antioxidant capacities of orange juice and gazpacho
were measured as free radical-scavenging capacity in a
DPPH model. Fresh untreated orange juice and gazpacho
exhibited 39.3% and 45.7% inhibition, respectively (Table
1). De Ancos et al. (2002) reported an inhibition of
37.5% DPPH in orange juice. Orange juice and gazpacho
showed differences in their compositions of bioactive compounds.
In this study, it has been observed that vitamin C
