Quick Answer: HPP stands for High Pressure Processing — a cold pasteurization method that uses water pressure instead of heat. AroJuice uses HPP to preserve the fresh flavour and quality of aronia berry juice without preservatives, allowing it to ship safely across Canada.
What Is High Pressure Processing (HPP)?
High Pressure Processing (HPP) is a food safety technology that uses extremely high water pressure — typically 600 MPa (about 87,000 PSI) — to inactivate harmful bacteria and extend the shelf life of fresh juices. Unlike traditional heat pasteurization, HPP does not use heat, so it does not cook or alter the flavour, colour, or nutritional profile of the juice.
HPP is widely used by premium cold-pressed juice brands to produce safe, shelf-stable juice without preservatives or additives. You will see HPP labelling on premium juices sold across Canada, the United States, and Europe.
Why Does HPP Matter for Aronia Juice?
Aronia juice is a sensitive, highly pigmented juice with a fragile polyphenol profile. Heat pasteurization can degrade some of the delicate flavour and pigment compounds in aronia berries. HPP processing allows AroJuice to maintain the fresh, bold, tart character of cold-pressed aronia while still meeting food safety standards for commercial distribution across Canada.
HPP vs Heat Pasteurization
Heat pasteurization uses temperatures above 72°C to kill pathogens. This is effective but can degrade heat-sensitive nutrients and alter the fresh flavour of juice. HPP achieves the same food safety outcome using pressure rather than heat, resulting in a juice that tastes closer to fresh-pressed. For aronia juice, which has a bold, distinctive flavour profile, HPP preservation is a significant quality advantage.
Is HPP Juice Safe?
Yes. HPP juice is safe and approved by Health Canada and food safety authorities worldwide. HPP is widely used by commercial juice producers, including many premium brands available in Canadian natural health stores and online.
