“…Indeed, this finding is consistent with a number of previous studies [ 9 , 32 ]. For example, the incorporation of bee pollen extract [ 33 ] and hazelnut extract [ 34 ] into κ-carrageenan-based films also resulted in the increase in film thickness.…”

In the present study, an anti-bacterial film (Carr/POM film) was prepared through the incorporation of Wells-Dawson polyoxometalate K6[Mo18O62P2] into κ-carrageenan-based polymers using the tape-casting method. The mechanical properties, thermal stability, and morphology of the prepared film were characterized. The obtained results showed that incorporation of K6[Mo18O62P2] significantly affected the morphology and structure of the films. Moreover, the polyoxometalate-based film demonstrated desirable bactericidal activity against Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive). Carr/POM (@8 mg/mL) film resulted in an obvious inhibition zone around the film in Kirby-Bauer disk diffusion test, which could also remove 99% of S. aureus and E. coli on plastic, glass, and stainless steel. In addition, this anti-bacterial film also demonstrated good biodegradability, which could be decomposed in soil in around 1 week. In conclusion, the polyoxometalate-based film showed good anti-bacterial property against food-borne pathogenic microbes, suggesting the prepared film has great potential to be developed as promising food packaging.

“…In fact, recent studies suggest pH‐responsive polymeric films as smart packaging materials for real‐time food freshness monitoring 279‐281 . In addition, the designed pH‐responsive films exhibit antioxidant activity, 282,283 antimicrobial activity, 284,285 or both, 46,286 making them suitable for food preservation. Apart from their functionalities, the attractivity of these systems resides in their nontoxicity for consumers.…”

Stimuli‐responsive materials in general and pH‐responsive polymers in particular have gained increasing interest during the last two decades. Their unique properties, which arise from their ability to exhibit sharp and reversible changes in response to environmental pH conditions, have made them suitable for various applications such as drug delivery and specific body‐site targeting, sensing and actuation, membrane functionalization, separation techniques, as well as in agriculture and food industry and even chemical industries. In the present review, the focus is on the general characteristics of pH‐responsive polymers in terms of their origin, chemical composition, and preparation. Moreover, some of the important and recent applications are reported and discussed.

“…These anthocyanins can therefore be incorporated into biopolymerbased smart packaging materials as pH sensors to monitor changes in the quality or spoilage of foods. This kind of smart packaging material has been shown to be useful for detecting quality changes in a number of food applications including, pork [162,164,199], shrimp [184], chicken [166,169], milk [200,201], pork, shrimp, fish [202][203][204], and Atlantic mackerel [205]. Other natural pigments are also available that undergo characteristic color changes when the pH is altered and so can also be used as sensors of food quality [16].…”

Interest in the development of smart and active biodegradable packaging materials is increasing as food manufacturers try to improve the sustainability and environmental impact of their products, while still maintaining their quality and safety. Active packaging materials contain components that enhance their functionality, such as antimicrobials, antioxidants, light blockers, or oxygen barriers. Smart packaging materials contain sensing components that provide an indication of changes in food attributes, such as alterations in their quality, maturity, or safety. For instance, a smart sensor may give a measurable color change in response to a deterioration in food quality. This article reviews recent advances in the development of active and smart biodegradable packaging materials in the food industry. Moreover, studies on the application of these packaging materials to monitor the freshness and safety of food products are reviewed, including dairy, meat, fish, fruit and vegetable products. Finally, the potential challenges associated with the application of these eco-friendly packaging materials in the food industry are discussed, as well as potential future directions.
