Modified Atmosphere Packaging (MAP) is a modern and much used method to protect oxygen sensitive items, most commonly foodstuffs and sterilised medical equipment.
Current oxygen sensors tend to be unreliable, due to their reversibility with oxygen, and are also typically costly with short shelf-lives.
New research at the University of Strathclyde has discovered a novel sensor for measuring oxygen levels within MAP. Critically, the sensor changes colour on the detection of oxygen.
Untrained personnel and end users can therefore monitor the oxygen level within the package to maintain product quality. The sensor is activated using UV light and remains unaffected by natural light.
Can this new form of packaging be applied to the aquaculture industry as well? This could be used to detect tampering and communicate product quality assurance to today’s quality concerned customers.
