Quick Answer: HPP (High Pressure Processing) is a non-thermal preservation method that uses cold water pressure instead of heat to preserve juice. Unlike conventional pasteurization, HPP avoids heat treatment, maintaining the fresh taste and natural character of the fruit. AroJuice aronia berry juice is cold-pressed and HPP processed in Ontario.
What Is HPP Processing?
High Pressure Processing (HPP) is a cold preservation technology used in premium juice production. Instead of heating juice to destroy harmful microorganisms, HPP applies intense water pressure — typically 600 MPa or more — to sealed bottles of juice. This pressure neutralizes pathogens and extends shelf life without exposing the juice to heat.
HPP vs Conventional Pasteurization
| Factor | HPP (AroJuice) | Heat Pasteurization |
|---|---|---|
| Heat Used | ✅ No heat | ❌ High heat required |
| Preservative Required | ✅ None | ⚠️ Sometimes added |
| Flavour Profile | ✅ Fresh, natural | ⚠️ Can alter taste |
| Shelf Life | ✅ Extended (refrigerated) | ✅ Long (shelf stable) |
| Natural Polyphenols | ✅ Preserved naturally | ⚠️ Heat can alter |
Why AroJuice Uses HPP
Welsdom chose HPP processing for AroJuice specifically because it avoids the compromises of heat pasteurization. Aronia berries are naturally rich in polyphenols and anthocyanins — and HPP allows the juice to be preserved without the heat that conventional pasteurization requires.
AroJuice is cold-pressed from whole aronia berries, then HPP processed in Ontario before being shipped across Canada. The result is a juice that tastes as close to fresh-pressed as possible, with no added preservatives.
