Led by James Blaxland, Ph.D., at Cardiff Met, the project will build on the research team's previous work developing standards for the safe application of ozone in food production environments.

Ozone, a naturally occurring gas comprising three oxygen atoms, has antimicrobial properties and can be used to control bacteria, viruses, molds, and pests. Unlike conventional chemical treatments, ozone decomposes rapidly into oxygen without leaving chemical residues. It can also penetrate hard-to-reach areas, potentially providing more comprehensive coverage than surface-only treatments.

The research will focus on developing regulatory guidelines for ozone use in food storage facilities, where maintaining food quality and safety over extended periods presents challenges. By controlling microbial contamination and slowing spoilage, ozone could help extend product shelf life and reduce food waste across the supply chain.

The project follows an earlier Knowledge Transfer Partnership through which the researchers developed principles for safe ozone application in food production facilities.

“Our earlier Knowledge Transfer Partnership laid the groundwork for safe ozone use in production facilities themselves,” Dr. Blaxland said. “With Innovate UK’s support, we can now extend those principles into storage, improving food safety standards while helping the industry tackle the critical issue of food waste.”

The researchers expect the project to produce practical guidelines, risk assessments, and industry-ready standards to support the safe implementation of ozone technology by food producers and storage operators.
