Differences between treatments (heat and HIPEF) could be also attributed
to the oxidative reactions that take place during thermal processing
and to the susceptibility of most of the bioactive compounds
contained in broccoli juice (vitamin C, TP, carotenoids, among others)
to heat (Shoji, 2007). Additionally, it is important to highlight that
throughout HIPEF treatments, the temperature of broccoli juice, at
the inlet and outlet of each HIPEF chamber, never exceeded 35 °C.
Therefore, bioactive compounds were better preserved by HIPEF than
by heat.
