High Pressure Processing The Future of Raw Food?

It is a process by which a food is subjected to high pressure, typically between 100 MPa up to 1,000 MPa for a certain period of time in order to kill bacteria and hopefully not damage nutrients much, if at all. ² It has been known that high pressure can kill bacteria since 1895.
