Phosphorescent Sensor Approach for Non-Destructive Measurement of Oxygen in Packaged Foods: Optimisation of Disposable Oxygen Sensors and their Characterization Over a Wide Temperature Range

Physical assessment of composite biodegradable films manufactured using whey protein isolate, gelatin and sodium alginate

“…Oxygen permeability was measured under controlled condition (50 ± 3% relative humidity, 23 ± 2°C) according to the method developed by Papkovsky et al (2000). The films were mounted between the upper lid and rubber ring with silicon lubricant and fixed to the lower cup by screws, with an oxygen sensor housed inside.…”

Non-destructive assessment of oxygen levels in industrial modified atmosphere packaged cheddar cheese

“…There is also a possibility to incorporate them into packaging materials. Their good sensitivity (0.02% of oxygen), dynamic range (0-100%) and the absence of cross sensitivity to other species (Papkovsky et al, 1995;Papkovsky et al, 2000), makes them suitable for a wide range of products.…”

“…Since the concept was first introduced (Fitzgerald, Papkovsky, OÕSul-livan, & Guilbault, 1998;Reininger, Kolle, Trettnak, & Gruber, 1996), considerable advancements have been made in the development of fluorescence-based oxygen sensors for packaging applications (Demas, DeGraff, & Coleman, 1999;Fitzgerald et al, 2001;Papkovsky, Papkovskaia, Smyth, Kerry, & Ogurtosov, 2000;Saini & Desault, 2002). In particular, our research team have developed a non-invasive, non-chemical and completely reversible system, which operates via a small plastic sensor elements incorporated in each pack and an external device-fluorescence phase detector.…”

Manufacture and characterization of gelatin films derived from beef, pork and fish sources using twin screw extrusion

“…Oxygen permeability was measured according to the method developed by Papkovsky et al (2000) and Wang et al (2007) under controlled condition (50 ± 5% RH and 23 ± 2°C). Prior to analysis, an oxygen sensor was placed inside the test chamber.…”
