HPP has potential as a phyto sanitary treatment to control
quarantine insect pests in fresh or minimal processed fruits
and vegetables to extend their shelf-life (7, 38). Pressure
inactivation of yeast and moulds has been reported in citrus
juices. Juices pressurized at 400 MPa for 10 min at 40oC did
not spoil during 2-3 months of storage (39, 40). The high
pressure treatment effectively reduced the bacterial flora
of fresh goat milk cheese and significantly extended the
refrigeration storage life No surviving E. coli was detected in
cheese after 60 days of storage (2-4oC) in inoculation studies
after treatments at 400-500 MPa for 5-10 min (9).
