high pressure processing 

high pressure processing is a cold pasteurization technique by which product already sealed in its final package are introduced into a vessel and subjected to a high level of isostatic pressure transmitted by water 


Pressures above 400 MPa / 58,000 psi at cold (+ 4ºC to 10ºC) or ambient temperature inactivate the vegetative flora (bacteria, virus, yeasts, molds and parasites) present in food, extending the products shelf life importantly and guarantee food safety.
High Pressure Processing retain the sensory and nutritional properties of food, because of the absence of heat treatment, and maintains its original freshness throughout the shelf-life 




Hpp is discussed because some abroad countries use high pressure processing for cane juice .
