Hiperbaric and CSIRO Develop Canister for High-Pressure Thermal Processing

To be unveiled during PACK EXPO Las Vegas at the Hiperbaric booth, No. N-10857

(Hiperbaric: Miami) -- Hiperbaric, a global leader in high-pressure technologies, will give an exclusive first look at an innovation that will improve food processing and preservation: high-pressure thermal processing (HPTP).

Invented by CSIRO, Australia’s national science agency, and further developed by Hiperbaric, HPTP combines the microbial lethality of heat with the rapid speed of high pressure into one revolutionary system.

At the core of HPTP is a canister patented by CSIRO that adds mild heat to existing Hiperbaric high-pressure processing (HPP) machines. The canister is capable of withstanding extreme pressure (87,000 psi/6,000 bar) and temperature conditions (>90°C), while keeping food products isolated from the surrounding water medium used.

The process is simple and compatible with all existing Hiperbaric HPP machines. Preheat the canister and food, hermetically seal, then use ultrahigh pressure to rapidly achieve sterilization temperatures.

This innovation is suitable for making some products microbiologically safe using far less heat compared to conventional food preservation technologies. Unlike conventional thermal pasteurization methods, HPTP enables sterilization at lower temperatures, maintaining the natural flavor, nutrients, and visual appeal of products.

This proprietary canister will enable a wide variety of products to benefit from the advantages of HPTP in a shelf-stable format.

By precisely controlling pressure and temperature, HPTP delivers major advantages: rapidly inactivating pathogens and spores to enable shelf-stable, low-acid products; preserving nutrition and flavor better than standard heat methods; reducing processing contaminants that can occur at high heat; and achieving commercial sterilization up to 10 times faster than conventional canning, based on research.

“We are thrilled to collaborate with CSIRO on this cutting-edge canister technology,” says Carole Tonello, VP of business development at Hiperbaric. “It represents a major breakthrough that will expand the applications for HPTP and help our food manufacturing partners deliver incredibly fresh-tasting, shelf-stable foods to consumers.”

Kai Knoerzer, principal research scientist at CSIRO, says, “At CSIRO, we’re committed to scientific excellence and innovation that can benefit industries globally. This project leverages our deep expertise in food processing, safety, and packaging to help bring a truly game-changing advancement to the market. We look forward to seeing the exceptional products this technology will enable.”

The proprietary canister will be unveiled during PACK EXPO Las Vegas at the Hiperbaric booth No. N-10857. With this new technology, Hiperbaric aims to revolutionize shelf-stable foods and beverages, providing exceptional quality that was previously only possible for refrigerated items.
