HOW DOES HPP WORK? By applying pressure in all directions uniformly for about one to three minutes, HPP foods retain their shape. The lack of heat (thermal processing) means HPP products taste better and retain their nutrients, which ensures producers deliver the absolute tastiest food on the planet.
What is the process of high pressure processing?
High pressure processing allows gentle preservation of food by high pressure without additives or heat. The food is conveyed in special baskets into a high-pressure vessel. It then moves into the machine and is filled with water.
What foods use HPP?
All kinds of foods undergo HPP:
- Ready-to-eat and ready-to-cook meats.
- Ready-meals.
- Fruits and vegetables.
- Juices and smoothies.
- Soups and sauces.
- Wet salads and dips.
- Dairy products.
- Seafood and shellfish.
What is high pressure technology?
High-pressure Technology (HPT), also described as high hydrostatic pressure (HHP) or ultra high pressure (UHP) processing, subjects liquid and solid foods, with or without packaging, to pressures between 100 and 800 MPa process temperature during pressure treatment can be specified from below 00C to above 1000C.
Is HPP pasteurized?
High Pressure Processing (HPP) is a cold pasteurization technique by which products, already sealed in its final package, are introduced into a vessel and subjected to a high level of isostatic pressure (300–600MPa/43,500-87,000psi) transmitted by water.
How much does a HPP machine cost?
To purchase and set up one HPP machine, it costs nearly $3 million. Plus, once you have the machine, you need a 24-hour support team for maintenance. Every night there is a two-hour breakdown for maintenance—oiling valves and such.
What is the disadvantage of HPP?
Disadvantages of HPP Spore-forming organisms are highly resistant to HPP when they are in their spore form. The spores of Clostridium botulinum, for example, can thrive in low-acid foods and produce a deadly toxin. HPP can cause undesirable sensory changes in certain foodstuffs.
Is high pressure pasteurization safe?
HPP promises the same level of food safety that heat pasteurization does, but without damaging the nutrients in fruits and vegetables. According to Dr. Barrett, several studies have found that vitamin C is relatively unaffected by the process for instance.

What is high pressure processing HPP?
Pascalization, bridgmanization, high pressure processing (HPP) or high hydrostatic pressure (HHP) processing is a method of preserving and sterilizing food, in which a product is processed under very high pressure, leading to the inactivation of certain microorganisms and enzymes in the food.
What is high pressure processing equipment?
High Pressure Processing Equipment Information. Show all High Pressure Processing Equipment Manufacturers. High pressure processing equipment is used to treat foods, beverages, proteins, enzymes, and other bioactive materials. Products are subjected to high pressures with or without the addition of heat to inactivate microbes and bacteria.
