High Pressure Processing

High Pressure Processing (HPP) – The Natural way to Preserve Foods and Beverages.

High Pressure Processing

Water: Pure and Powerful!

Quintus Technologies uses clean, fresh, cold water to create ultra-high pressures for inactivating foodborne pathogens and extending the refrigerated shelf life of foods and beverages. That is instead of using high temperatures and preservatives, including high levels of sodium containing additives.

This scientifically validated technology termed HPP (also known as high-pressure preservation, processing, pascalization or, cold pasteurization) is a post packaging, post lethality, non-thermal process that delivers food safety benefits and shelf-life extensions, without affecting the flavours, freshness and nutrients of premium foods and beverages.

Thus, HPP contributes to the prevention of foodborne illnesses, minimizing food safety recalls, reducing food waste, and delivering higher nutritious, better tasting, natural foods that we all deserve.

To place this in perspective, consider that, according to the United Nations Food and Agriculture Organization (FAO) and the World Health Organization (WHO), 600 million people fall ill each year from a foodborne illness and, 33% of all food produced for human consumption goes to waste, meaning that 25% of the world’s fresh water supply is used to grow food that never reaches our tables.

As a science based technology, HPP is not only fully recognized by global regulatory bodies as an antimicrobial process with superior capabilities for inactivating many food pathogens of concern, but also for slowing down the growth of spoilage bacteria, thereby extending refrigerated shelf life between 2-10 times longer than unprocessed foods.  Both these benefits alone can have a significant impact on the global challenges of food safety and food waste.

Most conventional food processing methods such as heat and/or chemicals have negative effects on health and nutrition. Consumers are demanding high nutritional values in foods, particularly those present in fresh, raw, or minimally processed varieties. HPP does not affect nutritional components in foods largely because it has no effects on covalent bonds so HPP products maintain their vitamins and bioactive compounds.

Manufacturers using HPP eliminate chemical preservatives used to control microbial growth and reduce the frequency of food safety testing, thus satisfying the demand from customers for preservative-free foods, while reducing operational costs, hence delivering higher company values.

HPP has thus become the process of choice among non-thermal food processing technologies. The assurance of inactivating foodborne pathogens, post packaging, provides food and beverage manufacturers the business-critical food safety confidence for protecting their consumers, as well as ensuring that their brands and company reputations remain untarnished.

How does HPP work

HPP works by placing packaged foods and beverages in a wire wound vessel, filling that vessel with pure water, then pressurizing the water and contents using specially designed intensifier pumps to reach as high as 87,000 psi (6,000 bars).

This pressure is distributed omnidirectionally allowing for uniform and instant affect throughout the product, regardless of product size, volume, or packaging material. Thus, a 10-gram package will be subject to the same pressure benefits as a 50-kilogram package – which is unlike thermal treatment or other intervention methods.

Water and foods will compress about 15% of their volume at 87,000 psi. Therefore, containers must be flexible enough to be compressed by at least that amount. All flexible plastic materials that are hermetically sealed are compatible with HPP. However, certain specifications of the materials such as oxygen and moisture barrier properties are critical for shelf-life extension.

HPP is commercially used in wide range of foods and beverages such as ready-to-eat deli meats, fruit and dairy based drinks, baby foods, dairy products, pet food, ready meals, ready-to-cook marinated meats and meals, seafood, and wide variety of plant-based products including guacamole, hummus, salsa, ready-to-eat salads, tofu and plant-based protein meat analogues.

Most food and beverages are applicable for HPP technology. However, certain intrinsic and extrinsic factors are important in determining HPP conditions and satisfying regulatory rules and guidelines.  Our newest Quintus HPP Application Centers are fully equipped to assist companies in the optimization of product formulas for HPP, providing guidance on packaging materials, conducting pathogen validation and shelf-life studies, and assisting in HACCP development and regulatory compliance.

Increase profitability with HPP

HPP is revolutionizing the way foods and beverages are preserved, allowing manufacturers and marketers to create innovative products that customers desire, such as preservative free, with all the natural nutrients present.  HPP also minimizes the use of energy and chemicals, which is positive from a sustainability perspective.

  • Premium products with a fresh taste – better mouthfeel for certain products.
  • Greater options for clean label products – the need for chemical preservatives is eliminated.
  • Higher nutritional value – bioactive components and covalent bonds are not affected.
  • Prolongs refrigerated shelf life 2 to 10 times longer – increased market reach.
  • Greater flexibility in production planning, raw material procurement and logistics.
  • Opportunities for new products – unique behaviour of hydrocolloid materials.
  • Reduced frequency of food safety testing – post packaging, post lethality process.
  • Fully compliant with global food safety regulations.
