The smoothie was pressurised with a semi-industrial Hiperbaric
55 (Hiperbaric, Burgos, Spain). The containers were weighed before
and after the treatments to ensure the goodness of the process. The
smoothies underwent two high-pressure treatments: 450 and
600 MPa. In both cases the time and temperature were maintained
constant (3 min, 20 C). HP processing was compared to thermal
treatment, as this is the most common option used in fruit juice
production.
The thermal processing (TP) was performed at 80 C for 3 min.
After heating, the samples were immediately cooled in an ice water
