High Pressure Processing Solutions: 100% Natural Flavor Retention
As consumers increasingly demand clean labels and authentic flavors, traditional thermal processing compromises between safety and quality have become a major barrier to brand innovation. HiLock HPP technology provides the ultimate solution — using pure physical pressure to achieve the perfect balance between safety and freshness.
More AboutA breakthrough technology that overcomes the limitations of traditional thermal sterilization, delivering safer, fresher, and cleaner-label food products.
Nutrient Loss
Heat treatment may reduce nutrients
and affect natural flavor.
Preservative Concerns
Chemical preservatives raise
consumer health concerns.
Short Shelf Life
Fresh products often have
limited storage time.
HiLock Solutions
Cold Sterilization
600MPa high-pressure processing inactivates harmful microorganisms while preserving vitamins and nutrients, achieving up to 99.9% microbial reduction.
Clean Label
No preservatives required. Achieve “zero additive” freshness and meet consumers’ demand for clean and natural products.
Extended Shelf Life
Cold storage shelf life can be extended from 30 to 120 days, reducing logistics costs and minimizing food waste.
HiLock HPP Application Cases
HPP Solutions for Raw Milk
Fresh milk naturally carries microorganisms, while traditional heat sterilization can damage heat-sensitive nutrients such as whey proteins and immunoglobulins, while affecting flavor and shelf-life stability. HiLock HPP cold pasteurization preserves over 95% of active proteins and immune nutrients, maintaining fresh milk flavor without cooked taste. As a clean-label solution with no extra additives, HPP-treated milk achieves 30–90 days of refrigerated shelf life, significantly reducing spoilage losses and providing high-quality, stable raw milk ingredients for further processing.
HPP Solutions for High-Quality Seafood Processing
HiLock provides state-of-the-art high pressure processing equipment and rapid service support to ensure uninterrupted production. Its HPP systems effectively inactivate common foodborne pathogens—such as Salmonella, Listeria, and norovirus—in fresh foods, enabling products to be stored stably under vacuum packaging for more than 18 days and significantly improving distribution flexibility. This technology preserves more than 90% of the fish’s natural proteins and fresh taste, keeping the fish firm, tender, and intact.

Frequently Asked Questions
-
What is HPP technology?
HPP exposes food to high pressure via a water medium for several minutes at low or room temperature, effectively killing bacteria, viruses, yeast, and mold.
-
What are the benefits of HPP technology?
HPP is globally recognized as an antimicrobial process that inactivates pathogens and slows spoilage bacteria, extending refrigerated shelf life 2–10 times. It preserves nutrients and bioactive compounds, maintaining vitamins and natural quality. This technology allows manufacturers to reduce chemical preservatives and lower food safety testing frequency.
-
In which fields can HPP technology be applied?
Applicable across multiple food processing scenarios, including juices and beverages, meat products, pet food, seafood, infant formula, dairy, as well as cosmetics and pharmaceuticals.
-
What is the difference between HPP technology and traditional sterilization methods?
Traditional sterilization methods (e.g., thermal processing) may damage nutrients and flavor, while high-pressure sterilization is performed at low temperatures, better preserving product quality, enhancing taste, and retaining natural nutrition that heat treatment cannot achieve.
