If you've been researching aronia berry juice or other premium fruit juices, you've probably seen the term "HPP" on the label. This article explains what HPP (High Pressure Processing) is, how it differs from heat pasteurisation, and why it matters when choosing aronia berry juice in Canada.
What Is HPP Processing?
HPP stands for High Pressure Processing — a cold preservation method that uses extremely high water pressure (typically 400–600 MPa) instead of heat to extend the shelf life of food and beverages. The product is sealed in its final packaging, submerged in cold water, and subjected to intense pressure for a short period of time.
This process inactivates bacteria and pathogens that could cause spoilage, achieving food safety standards without the need to apply heat, chemical preservatives, or UV treatment.
How Is HPP Different from Heat Pasteurisation?
Traditional juice pasteurisation heats juice to temperatures between 72°C and 90°C for a set period. This effectively kills bacteria, but it also degrades heat-sensitive compounds including certain vitamins, enzymes, and the volatile compounds responsible for fresh flavour.
HPP uses cold water pressure rather than heat, so the juice maintains a flavour profile much closer to fresh-pressed. The naturally occurring polyphenols and anthocyanins in aronia berries — the compounds responsible for the deep purple colour and antioxidant properties — are preserved more effectively compared to conventional heat treatment.
Why Does HPP Matter for Aronia Berry Juice?
Aronia berries have an unusually high concentration of anthocyanins and polyphenols compared to most other fruits. These compounds are naturally unstable — heat, oxygen, and light can all degrade them over time. HPP processing minimises the heat-related degradation that would otherwise reduce the concentration of these naturally occurring compounds during production.
The result is an aronia berry juice that tastes fresher and retains more of the berry's natural characteristics from the moment it's bottled to the day you open it.
Does HPP Aronia Juice Need to Be Refrigerated?
Yes. HPP juice has an extended refrigerated shelf life compared to fresh-squeezed juice, but it is not shelf-stable at room temperature. HPP aronia juice like AroJuice should be stored refrigerated and consumed by the best-before date on the bottle. Once opened, consume within a few days.
Is HPP Juice Safe?
HPP is approved for use in food and beverage production in Canada, the United States, and Europe. It is widely used for premium juices, deli meats, guacamole, and other food products where maintaining fresh flavour and avoiding heat treatment is a priority. HPP products must still meet all applicable food safety standards.
