An HIPEF treatment of 35 kV/cm, 1000 ls,
200 Hz and bipolar pulses of 4 ls led to 5.1 log reductions
in L. brevis inoculated in gazpacho (Martı´n-Belloso et al.,
2004). Even under these severe conditions, HIPEF-processed
foods retained more vitamin C and the antioxidant
capacity was higher than did the heat-treated products.
Therefore, stable orange juice and gazpacho, with minimal
changes in their health-promoting properties, could be
obtained by processing orange juice and gazpacho by
HIPEF.
