HPP = High Pressure Processing or Pasturization. It's essentially doing the same thing to the product as dehydration would, but maintaining the freshness and quality of the food. While dehydration makes a product shelf-stable for an extended period of time, HPP food still requires refrigeration but can stay fresh for up to 90 days (sometimes more)!
