Submission + - Scientists inject ozone into packaging to make food last longer (

An anonymous reader writes: Improving the shelf life of fresh, packaged food would cut down on waste considerably, and a group of scientists working out of the University of Glasgow think they have a solution — inject packaged food with ozone.

A retractable device is placed against the plastic (or glass) packaging, which turns some of the oxygen inside into ozone. It then remains in this form for a couple of hours and kills any bacteria/mold/fungi it encounters before reverting back to oxygen.

The end result is packaged food with a lot less bacteria contained within it and a treatment that has no impact on its taste. In real terms, it means the food gains at least an extra 24 hours of shelf life
