  • What is High Pressure Processing (HPP)? - Hiperbaric

    The pasteurizing effect of high pressure was recognized in the 19th century, when in 1899 Hite discovered the shelf life extension in milk using this process. However, it was not until the 1990s, that the first HPP products began to be marketed in Japan and Europe.

    High blood pressure (hypertension) is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease. Blood pressure is determined both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries.
