HPP is an external process. The raw, final product remains untouched. Picture this: After the juice is bottled, the bottles are placed into a pressure chamber filled with cool water for approximately 60 to 120 seconds, where they are subjected to elevated pressures (the equivalent of being submerged 20 miles beneath the ocean floor) from all directions to the outside of the bottle, starving off oxygen that in turn inactivates harmful, pathogenic bacteria…. WITHOUT a loss of sensory quality or nutritional value of juices.
