(p < 0.05) when the product was processed by the combinations
HILP + MTS, UV + MTS and UV + PEF and the reduction ranged between
19% and 24%. These treatments induced a significant decrease
(p < 0.05) in the anthocyanin content, which was similar
to the thermally treated sample. In contrast, when the effect on
anthocyanins was assessed after treatment with either UV or HILP
as a first hurdle, no significant changes were observed compared to
the untreated control. The percent of polymeric colour of all the
non-thermally treated samples was not significantly different from
the control (mean value 84%), and this is in agreement with the
NEBI results reported previously.
