compare the hyperbaric storage of
food at room temperature, as a new preservation technique, to refrigeration, a well-established method. To do that, storage experiments
were carried out at different pressures (0.1, 25, 100 and 220 MPa)
and 20 °C in raw strawberry juice, a simple liquid matrix appropriate
for these initial experiments and widely employed as a food
ingredient. After 15 days of storage, some safety and quality attributes (microbial population, viscosity and color) were measured
and compared to those of raw and pasteurized juice samples stored
at atmospheric pressure and 5 °C for the same period. The stability
of the samples after decompression was also studied to know if the
juice should be immediately processed or consumed after the hyperbaric storage or if it remains stable, in refrigeration, for some time. All
the results obtained in this paper can provide important information
to evaluate the viability of hyperbaric storage at room temperature
for food preservation.
