High pressure processing (HPP) technology attracted attention in the 1980s as a non-thermal sterilization method, and its research, development and practical application were promoted in Japan. High pressure food processing equipment, which did not spread widely at that time, is now seeing increased demand due to recent situational changes in food companies in Japan. Conventional, vertical, cold-isostatic-pressing (CIP) apparatuses are difficult to install in the facilities of food companies; hence, a horizontal CIP apparatus, "FOOD FRESHER," has been developed. This paper describes the situation in high-pressure food processing technology and outlines the newly-developed FOOD FRESHER and its future development.
