“…The TEMPO oxidation process effectively yielded BC with a high aspect ratio, which considerably reinforced the KC matrix. 36 This enhancement can be attributed to the robust electrostatic interaction between OBC and CMCS. Notably, with the inclusion of ACT NPs, the TS and EAB of the KCOA film increased to 42.25 MPa and 139.1%, respectively (Figure 4a,b).…”

Food safety concerns arising from undetected food spoilage pose a significant risk to consumer health and well-being. Concurrently, the extensive utilization of nonbiodegradable petroleum-based plastic packaging films contributes to environmental degradation. Therefore, it is important to develop biodegradable food packaging materials endowed with active and intelligent functionalities for mitigating food wastage and safeguarding food integrity. This study focused on the synthesis of anthocyanin-curcumin-tannic acid nanoparticles (ACT NPs) through metal ion coordination and multiple hydrogen bonds to enhance the stability of active substances. Additionally, oxidized bacterial cellulose (OBC) was employed to improve the mechanical properties and biocompatibility of KCOA film. Drawing inspiration from self-wrinkling biomaterials, a sustainable multifunctional wrinkle-structured food packaging film was fabricated using the solution casting method. The resulting KCOA film exhibited exceptional attributes, including mechanical strength, reduced gas permeability, water resistance, ultraviolet-blocking capability, degradability, antioxidative properties, antimicrobial activity, and pH responsiveness. In pork preservation trials, the film considerably prolonged the shelf life of products while enabling the real-time monitoring of spoilage. This study presents a novel methodology for producing sustainable multifunctional wrinkle-structured films and underscores their potential as versatile packaging materials for concurrent food preservation and freshness monitoring.

Owing to the environmental pollution caused by petroleum-based packaging materials, there is an imminent need to develop novel food packaging materials. Nanocellulose, which is a one-dimensional structure, has excellent physical and chemical properties, such as renewability, degradability, sound mechanical properties, and good biocompatibility, indicating promising applications in modern industry, particularly in food packaging. This article introduces nanocellulose, followed by its extraction methods and the preparation of relevant composite films. Meanwhile, the performances of nanocellulose composite films in improving the mechanical, barrier (oxygen, water vapor, ultraviolet) and thermal properties of food packaging materials and the development of biodegradable or edible packaging materials in the food industry are elaborated. In addition, the excellent performances of nanocellulose composites for the packaging and preservation of various food categories are outlined. This study provides a theoretical framework for the development and utilization of nanocellulose composite films in the food packaging industry.

“…Moreover, anthocyanins are pH-sensitive substances that exhibit a gradient color change for different pH values. Anthocyanins undergo a continuous structural change from flavonoid ions under acidic conditions to quinone structures under alkaline conditions, as seen in Figure 20 [326]. Additionally, anthocyanins also display potent antioxidant activity, which can be useful to prevent color change or lipid oxidation of packaged food products [327].…”

The research of starch as a matrix material for manufacturing biodegradable films has been gaining popularity in recent years, indicating its potential and possible limitations. To compete with conventional petroleum-based plastics, an enhancement of their low resistance to water and limited mechanical properties is essential. This review aims to discuss the various types of nanofillers and additives that have been used in plasticized starch films including nanoclays (montmorillonite, halloysite, kaolinite, etc.), poly-saccharide nanofillers (cellulose, starch, chitin, and chitosan nanomaterials), metal oxides (titanium dioxide, zinc oxide, zirconium oxide, etc.), and essential oils (carvacrol, eugenol, cinnamic acid). These reinforcements are frequently used to enhance several physical characteristics including mechanical properties, thermal stability, moisture resistance, oxygen barrier capabilities, and biodegradation rate, providing antimicrobial and antioxidant properties. This paper will provide an overview of the development of starch-based nanocomposite films and coatings applied in food packaging systems through the application of reinforcements and additives.
