What is High Pressure Processing?
High pressure processing (HPP) is a method of preserving and sterilizing food using pressure. It works by placing sealed containers of hummus in a chamber that is filled with cold water. Up to 87,000 psi is applied (more than the bottom of the ocean), neutralizing any dangerous microbes. As opposed to other methods which use heat and/or chemicals, HPP has no effect on taste or texture. It even doubles the shelf life, reducing waste due to spoiling. A win, win, win!
