About the Cold Plasma Research Project

WHAT IS THE NEED?

Improving food safety can provide a competitive advantage for Australian horticultural industries.
Foodborne illnesses caused by microbial contamination in fresh produce and nuts can lead to product recalls, loss of consumer confidence and trade disruption – all of which cause economic losses to industry.

WHAT IS COLD PLASMA? 

Cold plasma is created by applying an electric current to normal air or a gas. This produces reactive gaseous species found to have broadspectrum antimicrobial activity. Cold plasma is effective at temperatures slightly above ambient, which means produce can be treated without being heated.

WHAT ARE THE BENEFITS?

The benefits to be achieved through Cold Plasma technology include improving food safety and reduced postharvest losses due to decay; reducing treatment time of a few seconds to minutes and providing energy efficient treatment with zero chemical residue.

PROJECT OBJECTIVES 

To develop a decontamination technology based on cold plasma that can kill or inactivate food borne pathogens and rot-causing microbes on fresh produce.  Collaboration with technology partner(s) and horticultural industries to validate, scale-up and commercialise this technology.

EXPECTED PROJECT OUTCOMES

A new tool to reduce food safety risks to consumers and industry; and more competitive Australian horticultural industries in both domestic and export markets.

TARGET BENEFICIARIES

Horticultural growers, processors and packers of commodities of such as:

Fruit: Apple, Blueberry, Citrus, Strawberry
Nuts:  Macadamia and Almonds
Vegetables:  Spinach and Lettuce
Fresh-cut fruit and vegetables

Funding: This project has been funded by Horticulture Innovation Australia Limited with co-investment from NSW Department of Primary Industries and funds from the Australian Government.

Our research aims to support the horticultural industries in supplying fresh, safe and nutritious products to consumers in domestic and export markets
