The industry is actively seeking environmentally friendly and straightforward techniques for creating the necessary polymeric films with advanced functionality. In line with this, the current study is centered on the fabrication of antibacterial PEG-like coatings that are enriched with nitrogen-containing groups. This is achieved through an aerosol-assisted atmospheric pressure plasma polymerization technique using tri(ethylene glycol) divinyl ether as precursor. To attain this, nozzles with various geometries were employed at the periphery of the plasma head. This nozzle arrangement was instrumental in altering the deposition process and controlling the duration for which the monomer remains within the plasma. As a result, the incorporation of nitrogen-containing functional groups could be achieved directly during PEG plasma polymerization. The findings clearly demonstrate that the use of nozzles exerts a critical influence in shaping the physicochemical properties of the deposited PEG-like coatings. This influence arises from alterations in gas dynamics and residence time of monomer in plasma. By optimizing the monomer residence time, it becomes possible to produce smooth and conformal coatings that exhibit high hydrophilicity, retain PEG functionality, and contain nitrogen-containing functional groups. These latter coatings have demonstrated remarkable antimicrobial activity against <em>E. coli</em> (resulting in a 4.8 log reduction) and <em>S. aureus</em> (with a 2.1 log reduction), primarily due to the existence of nitrogen-rich functionalities on the coating surface.

This review provides a thorough analysis of the mechanisms underlying the monitoring of food freshness biomarkers, the production of smart chitosan film, the integration of sense-active compounds, the biodegradation patterns, cytotoxicity and safety concerns, and the significant challenges to sustainable implementation. Several sense-active compounds from plant extracts, including anthocyanins, alizarin, betalains, and curcumin, have been employed to fabricate smart chitosan films. The most common freshness biomarkers: ammonia, pH, total volatile basic nitrogen (TVBN), and thiobarbituric acid reactive substances (TBARS), are considered for assessing fish, meat, and milk quality using smart chitosan films. However, the responsive nature of the film to different freshness biomarkers depends on the sources and type of sense-active compounds incorporated in the film.

Here, we attempt to overcome this issue by blending PLA with a suitable sorbitan-based non-ionic surfactant, which increases its surface-free energy and wettability. Among various sorbitan-based surfactants, sorbitan monopalmitate (Span 40) was found to be more efficient in promoting good wetting and, thereby, preventing the formation of foggy droplets.

Our findings reveal that incorporating shellac and LDH-NS significantly improves the coating's wettability on the mandarin fruit surface, thus bolstering its adherence and uniformity, alongside enhancing its water vapor barrier efficacy and influencing the oxygen permeability. The application of this novel edible nanocomposite coating on Satsuma mandarin (<em>Citrus unshiu</em> Marc.) fruits has yielded promising outcomes in prolonging postharvest shelf life while preserving essential quality attributes, including peel surface morphology, weight loss, hardness, color retention, and nutritional values. Our work signifies a significant leap forward for the edible coating technology and bolsters the postharvest preservation of perishable fruits.</div></div>","PeriodicalId":12377,"journal":{"name":"Food Packaging and Shelf Life","volume":"46 ","pages":"Article 101364"},"PeriodicalIF":8.5,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142426056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
