Precision for Food Innovation
Built for R&D labs and pilot plants, our HPP systems deliver the level of control required for food innovation. Operating up to 10,000 bar and within a temperature range of -20°C to +100°C, they allow precise adjustment of pressure and thermal conditions. Researchers can evaluate both cold pasteurization for fresh products and pressure-assisted thermal sterilization (PATS) for shelf-stable applications. During each cycle, temperature and pressure are continuously recorded to support analysis and certification.
Meat
High Pressure Processing is a proven method to enhance the safety and extend the shelf life of ready-to-eat (RTE) meat products. By applying pressure post-packaging, HPP effectively eliminates pathogens like Listeria without the need for chemical preservatives or high heat, preserving the natural flavor, texture, and nutritional value of the product.
Key benefits
- Pathogen inactivation
Proven to eliminate Listeria, Salmonella, and E. coli. - Clean label
Extends shelf life without chemical additives. - Enhanced saltiness
Allows for sodium reduction without compromising taste. - Preserved quality
Maintains the sensory and nutritional profile of the meat.
Seafood
HPP revolutionizes seafood processing by dramatically improving both safety and yield. For shellfish like oysters and lobsters, the pressure instantly detaches the meat from the shell, allowing for 100% meat recovery with minimal labor. The process also eliminates harmful bacteria such as Vibrio, ensuring a safer product with a longer shelf life.
Key benefits
- Increased yield
Achieves 100% meat recovery from shellfish. - Reduced labor
Automates the shucking process, saving time and cost. - Enhanced safety
Eliminates pathogens like Vibrio. - Extended shelf life
Keeps seafood fresh for longer, reducing waste.
Juice & Beverages
HPP is the technology behind the success of the premium cold-pressed juice market. It allows for the preservation of juices and beverages for weeks or even months, without the degradation of flavor, color, and vitamins that occurs with heat pasteurization. This enables brands to offer clean-label, high-quality products with a national distribution reach.
Key benefits
- Superior quality
Preserves the fresh taste, color, and nutritional value. - Massive shelf life extension
Extends shelf life from days to months. - Clean label
No need for chemical preservatives. - Market expansion
Enables local brands to achieve broader distribution.
Ready-to-eat Meals
For the convenience food market, HPP offers a way to deliver fresh, safe, and preservative-free ready-to-eat meals. From soups and sauces to complete meal kits, HPP extends shelf life for several weeks while maintaining the high quality and fresh taste that consumers demand, bridging the gap between convenience and clean-label eating.
Key benefits
- Extended shelf life
Keeps ready meals fresh for weeks. - Enhanced food safety
Inactivates spoilage microorganisms and pathogens. - Clean label
Creates convenient meals without artificial preservatives. - Maintained freshness
Preserves the taste and texture of freshly prepared food.
Petfood
The raw pet food trend is growing rapidly, but it comes with significant safety challenges. HPP provides a solution by eliminating pathogens like Salmonella and Listeria in raw pet food formulations without cooking the product. This ensures the food remains raw and retains its full nutritional value, offering pet owners a safe and healthy option.
Key benefits
- Guaranteed safety
Eliminates pathogens in raw pet food. - Nutritionally intact
Preserves the nutritional benefits of a raw diet. - Clean label
No need for chemical preservatives. - Market growth
Meets the consumer demand for safe, raw pet food.
Dairy
HPP opens up new possibilities for innovation in the dairy sector. It can be used to extend the shelf life of fresh cheeses, yogurts, and milk-based spreads, while also offering unique opportunities to modify textures and create novel dairy products. Research is also exploring HPP as a viable alternative to thermal pasteurization for milk itself.
Key benefits
- Extended shelf life
Increases the shelf life of fresh dairy products. - Texture modification
Enables the creation of novel textures in yogurts and cheeses. - Product innovation
Supports the development of new, clean-label dairy products. - Enhanced safety
Reduces the microbial load in dairy formulations.
Baby Food
Parents are increasingly seeking fresh, nutritious, and preservative-free options for their children. HPP meets this demand perfectly by ensuring the safety of baby food while preserving its vital nutrients, fresh taste, and natural color. It allows for the creation of clean-label baby foods that are as close to homemade as possible.
Key benefits
- Maximum nutrition
Preserves vitamins and nutrients sensitive to heat. - Enhanced safety
Eliminates harmful pathogens critical for infant health. - Clean label
No need for artificial preservatives, colors, or flavors. - Fresh taste & appearance
Creates baby food that looks and tastes fresh.
Guacamole
Guacamole was one of the first and most successful applications of HPP. The technology extends the shelf life of fresh guacamole from just a few days to over a month, preventing browning and preserving the fresh taste and vibrant color of the avocado. This breakthrough turned a regional product into a global supermarket staple.
Key benefits
- Prevents browning
Maintains the bright green color of fresh avocado. - Extended shelf life
Extends shelf life from days to weeks. - Clean label
No need for preservatives or additives. - Preserved freshness
Retains the authentic taste and texture of fresh guacamole.
