Clean Juice's Shift to High-Pressure Processing (HPP)
For years, Clean Juice prided itself on providing fresh, organic, cold-pressed juices made on-site at each location. This method appealed to customers seeking a raw, nutrient-dense product. However, as the company expanded and faced supply chain and consistency challenges, it announced a pivot in its production process in late 2022. To improve operational efficiency, ensure product consistency, and lengthen the shelf life of its bottled offerings, Clean Juice transitioned to a centralized production model using High-Pressure Processing (HPP).
This move addressed several key business needs, including managing production across a growing number of franchise locations and minimizing ingredient waste. For consumers, this meant a more consistent product available for longer, though it changed the core nature of the bottled juices from raw to pasteurized. The key distinction, however, is the type of pasteurization used—HPP is a 'cold' method that avoids the destructive heat of traditional pasteurization.
What is High-Pressure Processing (HPP)?
HPP is an advanced food preservation technique that uses immense water pressure, not heat, to neutralize foodborne pathogens and spoilage microorganisms. During this process, sealed bottles of juice are placed in a chamber filled with water. The chamber is then pressurized to extremely high levels (up to 87,000 pounds per square inch), which effectively destroys bacteria like E. coli, Salmonella, and Listeria.
The advantage of HPP is that the high pressure is applied uniformly throughout the bottle and does not affect the delicate nutrients, enzymes, color, or flavor of the juice in the same way that heat does. This allows the product to maintain a fresher taste and higher nutritional integrity while still achieving a significant extension of its shelf life and enhanced food safety.
Benefits of Clean Juice's HPP Process
Using HPP offers several notable benefits for both the company and the consumer.
- Enhanced Food Safety: HPP provides a scientifically validated method for eliminating harmful pathogens, significantly reducing the risk of foodborne illness associated with raw or untreated juice.
- Extended Shelf Life: By destroying microorganisms, HPP dramatically extends the shelf life of the juices, allowing them to be distributed more widely and reducing the frequency of in-store juicing, which was previously a logistical challenge.
- Maximized Nutrient Retention: Unlike traditional heat pasteurization, HPP does not use heat, which preserves the valuable heat-sensitive vitamins (like Vitamin C), minerals, and enzymes that are often degraded by high temperatures.
- Preserved Flavor and Color: The non-thermal nature of HPP means the juice retains its vibrant, fresh flavor and color, offering a premium drinking experience closer to that of truly fresh-pressed juice.
- Increased Accessibility: Centralized HPP production allows Clean Juice to ensure consistent quality and availability across all its locations, making their signature cold-pressed juices more accessible to a wider audience.
HPP vs. Traditional Pasteurization: A Comparison
To fully understand why HPP is a preferred method for many premium juice brands, it helps to compare it directly with traditional heat pasteurization.
| Feature | High-Pressure Processing (HPP) | Traditional Heat Pasteurization |
|---|---|---|
| Preservation Method | High hydrostatic pressure transmitted by cold water | Heating juice to high temperatures (e.g., 160–185°F) |
| Effect on Nutrients | Minimal impact on heat-sensitive vitamins, enzymes | Can degrade or destroy some heat-sensitive nutrients |
| Effect on Flavor | Preserves fresh, natural flavor and color | Often results in a slightly 'cooked' or less fresh taste |
| Effectiveness | Effectively kills pathogens, extending shelf life | Effectively kills pathogens, extending shelf life |
| Shelf Life | Provides an extended refrigerated shelf life | Can provide very long shelf life, sometimes unrefrigerated |
| Consumer Perception | Viewed as a premium, minimally processed method | Often associated with lower-quality, mass-produced juices |
The Verdict for Clean Juice Consumers
For those who were long-time fans of Clean Juice's raw, in-store pressed products, the shift to HPP for bottled juices represents a change. However, it is a change that prioritizes food safety and accessibility without compromising the core principles of delivering a fresh-tasting, nutrient-dense product. The use of HPP allows Clean Juice to provide a safer product with a longer shelf life while minimizing the loss of nutritional value associated with older pasteurization techniques.
It is worth noting that while the bottled juices are now centrally produced using HPP, Clean Juice still maintains a focus on using organic ingredients. For customers, this means they can enjoy the benefits of a longer-lasting product that is still organic and packed with nutrients, all with a greater peace of mind regarding food safety.

Conclusion
In summary, the answer to the question, "Is Clean Juice pasteurized?" is a nuanced yes. While the company no longer sells truly raw, unpasteurized bottled juice, it utilizes the advanced, non-thermal High-Pressure Processing (HPP) method for its packaged products. This process effectively kills harmful bacteria, dramatically extends shelf life, and, importantly, preserves the vibrant flavor and high nutritional content that a heat-based method would destroy. For the modern consumer, this provides a safe, accessible, and high-quality organic juice option that balances freshness with food safety innovation.
