“…For the production of oxygen-indicating tag, one gram of carrageenan was dissolved in 90% ethanol ( w / v ) and glycerol (7.2%, w / v ), and titanium dioxide (7.2%, w / v ) was added along with PEO (20%, w / v ). The quantity of carrageenan was chosen from Deshwal and others [ 7 ]. The selected dye (resazurin sodium salt) was dissolved in a small amount of solvent that was later mixed with the biopolymer solution.…”

Pack integrity is essential for the success of modified atmosphere packaging of food products. Colorimetric oxygen leak indicators or tags are simple and smart tools that can depict the presence or absence of oxygen within a package. However, not many bio-based electrospun materials were explored for this purpose. Ultraviolet light-activated kappa-carrageenan-based smart oxygen indicating tag was developed using the electrospinning technique in this study and its stability during storage was determined. Kappa-carrageenan was used with redox dye, sacrificial electron donor, photocatalyst, and solvent for preparing oxygen indicating electrospun tag. Parameters of electrospinning namely flow rate of the polymer solution, the distance between spinneret and collector, and voltage applied were optimized using Taguchi L9 orthogonal design. Rheological and microstructural studies revealed that the electrospinning solution was pseudoplastic and the mat fibers were compact and non-woven with an average fiber size of 1–2 microns. Oxygen sensitivity at different oxygen concentrations revealed that the tag was sensitive enough to detect as low as 0.4% oxygen. The developed tag was stable for at least 60 days when stored in dark at 25 °C and 65% RH. The developed mat could be highly useful in modified atmosphere packaging applications to check seal integrity in oxygen devoid packages.

“…As and when headspace oxygen increases due to atmospheric air ingress, food’s deteriorative reaction rate increases. Hence, to check the efficacy of MAP, gas leak indicators or sensors can be used [ 7 ]. Most animal-origin foods including meat, fish, and dairy products are MAP packaged in oxygen-deprived atmospheres.…”

“…Correlation between oxygen concentration and microbial growth presented an opportunity for assessment of cheese quality using colorimetric oxygen sensor [74]. Similarly, dye based ultraviolet light activated oxygen sensor was successfully developed and characterized for its oxygen sensitivity, oxygen dependent color change and mechanical properties by Deshwal et al (2018) [75]. The developed indicator was integrated with MAP Mozzarella cheese as an integrity/oxygen indicator, which could be helpful for stakeholders in the entire supply chain [15].…”

Technological advances and changes in consumer preferences for safer food with better shelf life have led to packaging innovations like smart packaging. Smart packaging systems involve the blend of active and intelligent packaging properties. Most of the smart packaging systems in food sector are mainly focused on fish, sea, food, meat, poultry, fruits and vegetables. With cheese being the major dairy product and its market expanding exponentially, smart packaging systems for cheese are exhaustively addressed in this book chapter. Some of the smart packaging systems pertaining to cheese like antioxidant releasers, antimicrobial packaging, ripening indicator and self-cleaning rinds can hasten commercial acceptance and reliability of cheese products. This book chapter also tabulates the recent data related to production, and consumption of cheese, permitted additives, types of active and intelligent packaging systems explored for cheese and commercial suppliers of smart packaging systems. Along with, future research directions for smart packaging of cheese are also presented.

Titanium Dioxide Nanotube-Based Oxygen Indicator for Modified Atmosphere Packaging: Efficiency and Accuracy

Colorimetric oxygen indicators can be applied for non-destructive testing in packaging; especially in modified atmosphere packaging (MAP). In this paper; titanium dioxide (TiO2) nanotube; which is used as a semiconductor photocatalyst in oxygen indicators; was synthesized via a microwave-assisted hydrothermal method. X-Ray Diffraction (XRD) was used to analyze its crystal form and Scanning Electron Microscope (SEM).to characterize its morphology. Its properties were studied using Brunauer-Emmett-Teller (BET), Diffuse Reflection Spectrum (DRS), and Bluebottle experiments. The results showed that the synthesized TiO2 nanotube was a mixture of rutile and anatase; with a specific surface area of 190.35 m2/g; and a wide band gap of 3.34 eV. Given the satisfactory performance; the TiO2-based oxygen indicator was prepared and combined with glycerol; methylene blue; and hydroxyethyl cellulose (HEC). The oxygen indicator demonstrated excellent photocatalytic performance and effectively avoided excitation by visible light. We studied the rheological properties; thixotropic properties; and wettability of the indicator. The results demonstrated the printability of the indicator solution; which was then printed in the polyethylene terephthalate (PET) film by screen printing and applied to MAP. The application results showed that the prepared oxygen indicator was able to provide visual support to judge whether the packaging was intact and the food was safe.
