variation, instant high pressure and pressure change
produced by ultrasonic cavitation effect in liquid are used
to kill some bacteria, inactivate virus or even damage cell
wall of some smaller microbial so as to extend the
storage time of fruit and vegetable.
Super ice-temperature technology and ice film
storage technology
Current research on ice-temperature technology is
entering a new stage which is super ice-temperature
technology. By adjusting the cooling speed and using
other special techniques, temperature even below
freezing point also can successfully keep super-cooled
state, so in super ice-temperature field, though the
temperature is below the normal freezing point,
organisms also won't freeze. Super ice-temperature
technology further widens the ice-temperature application
field. If the research on this technology can be further

developed, super fresh-keeping era will come. Presently,
it has confirmed that comparing with positive temperature
field in which oxidation and aging reaction happens,
reduction reaction of some seeds in ice-temperature and
super ice-temperature field can happen basically without
oxygen.
Ice-temperature storage must preserve food in negative
temperature area that is below 0°. Because when storing
some low sugar food especially for that of layered
structure such as cabbage vegetables at ice temperature,
they can easily appear the phenomenon of dry
consumption, low temperature cold injury or partly frozen.
A lot of experiments and research successfully advance
ice film storage technology, which means that by
covering a layer of artificial ice or snow or other protective
film on the food surface, dry consumption and low
temperature cold injury phenomenon could be avoided
because of cold air directly through the surface of food.
CONCLUSION
Compared with the traditional storage technology,
physical preservation technique can fully retain food
nutrients and the original flavor, and even generate some
favorable special flavor, so the application of physical
technology in fruit and vegetable fresh-keeping has huge
production potential and a promising prospect.
