How much pressure can the HPP machine withstand?

The correct choice indicates that high-pressure processing (HPP) machines can withstand pressures of around 90,000 psi. This high level of pressure is essential for the HPP technology, which utilizes extreme pressure to inactivate pathogens and extend the shelf life of food products without the need for preservatives or heat.

In the process, food items are placed in a sealed chamber and subjected to this pressure, which is evenly distributed throughout the product. Such high pressures can cause cellular changes in bacteria, yeasts, molds, and even some enzymes, effectively ensuring food safety and maintaining nutritional quality. The effectiveness of HPP as a food preservation method hinges significantly on this capability to achieve and maintain such elevated pressure levels.
