Abstract: High pressure process technology is now a new,advanced technology in food process industry in the world.This paper introduced specifically the principle of high-pressure process technology and the characteristics of high-pressur food The goals were (1) to retain nutritive value of food;(2)to retain primary color and taste of food;(3)to conserve energy and shorten process time;and (4)to prolong the product shelf-life and simplify process technology.The application results expected of high pressure technology to food process were :high-pressure sterilizing effect, high-pressure freeze ,high-pressure thaw and refrigeration without freeze,improvement of quality and taste of food and effective processing equipment.

Key words: high-pressure food High-pressure process High-pressure killing bacteria.
