“…PET films may also delay the color change to blue with a low oxygen permeability. In addition, the film can elongate the storage time for three weeks in a refrigerator [ 106 ]. When MMT–copper oxide nanocomposites (MMT-CuO) were incorporated into the chitosan matrix, it improved the optical, mechanical, and antibacterial properties.…”

A recent focus on the development of biobased polymer packaging films has come about in response to the environmental hazards caused by petroleum-based, nonbiodegradable packaging materials. Among biopolymers, chitosan is one of the most popular due to its biocompatibility, biodegradability, antibacterial properties, and ease of use. Due to its ability to inhibit gram-negative and gram-positive bacteria, yeast, and foodborne filamentous fungi, chitosan is a suitable biopolymer for developing food packaging. However, more than the chitosan is required for active packaging. In this review, we summarize chitosan composites which show active packaging and improves food storage condition and extends its shelf life. Active compounds such as essential oils and phenolic compounds with chitosan are reviewed. Moreover, composites with polysaccharides and various nanoparticles are also summarized. This review provides valuable information for selecting a composite that enhances shelf life and other functional qualities when embedding chitosan. Furthermore, this report will provide directions for the development of novel biodegradable food packaging materials.

“…Recent studies have started looking into developing safer products such as edible pH sensor 52 and natural product-based oxygen indicators. 53 However, studies conducted by Aday and Yener, 54 and O'Callaghan and Kerry 55 found that from a consumer point of view, the perceived risk of being misled with innovative packaging claims was still a barrier to adoption. Consumers may be more willing to accept a technology after viewing educational commercials.…”

In this paper, we attempt to better understand concerns, needs and expectations of European consumers towards the use of intelligent packaging technologies as this topic appears to need further investigation from a marketing point of view. Thus, this study contributes to the currently limited body of research on the application of smart tag technologies on food packaging by exploring information benefits to consumers and by providing insights for marketers on how these technologies could be further employed to create value for consumers, manufacturers and regulatory bodies.A qualitative user-centred approach was employed to get insights about consumers' shared views on future packaging solutions that could be introduced by European stakeholders of the food industry using different smart labels. Focus group discussions (FGDs) were conducted online in five European countries: United Kingdom,

“…Methylene blue was reduced to its colorless form by glucose and turned blue on exposure to oxygen. Films based on these polymers demonstrated storage stability at low temperatures, which makes them an excellent option for cold-stored food products due to their effectiveness as colorimetric oxygen indicators [137].…”

Natural cyclodextrins (CDs) can be formed by 6, 7, or 8 glucose molecules (α-, β-, and γ-, respectively) linked in a ring, creating a cone shape. Its interior has an affinity for hydrophobic molecules, while the exterior is hydrophilic and can interact with water molecules. This feature has been used to develop active packaging applied to food, interacting with the product or its environment to improve one or more aspects of its quality or safety. It also provides monitoring information when food is optimal for consumption, as intelligent packaging is essential for the consumer and the merchant. Therefore, this review will focus on discerning which packaging is most appropriate for each situation, solubility and toxicological considerations, characterization techniques, effect on the guest properties, and other aspects related to forming the inclusion complex with bioactive molecules applied to packaging.
