文摘With over 141 million tons of packaging waste generated globally each year and limited recycling efficiency,packaging pollution has become a pressing environmental issue,driving increased scholarly interest in green packaging.However,existing studies have primarily focused on individual domains,lacking a systematic and comprehensive review,which restricts interdisciplinary integration and obscures overarching trends and gaps.To address this,we conducted a bibliometric analysis of green packaging research using CiteSpace and VOSviewer,drawing on peer-reviewed English-language articles published between 2000 and 2023 in the Web of Science Core Collection.The analysis examined collaboration networks,co-citation patterns,and keyword co-occurrence trends.Results reveal significant growth in publications since 2018,with research spanning environmental science,food technology,and business,alongside increasing interdisciplinary integration.Collaboration networks are particularly strong within China and Malaysia,though international collaboration remains limited,while co-citation analysis highlights high-impact work on material performance,consumer behavior,and supply chain strategies,with life cycle assessment emerging as the most widely applied analytical tool.This study synthesizes the current knowledge framework,identifies key trends and challenges,and outlines future research directions-including consumer payment behavior,corporate sustainability strategies,and the development of innovative packaging materials-providing strategic guidance for advancing green packaging research.

文摘Petrochemical plastics are widely used for food protection and preservation;however,they exhibit poor biodegradability,resisting natural degradation through physical,chemical,or enzymatic processes.As a sustainable alternative to conventional plastic packaging,edible films offer effective barriers against moisture,gases,and microbial contamination while being biodegradable,biocompatible,and environmentally friendly.In this study,novel active food packaging materials(in film form)were developed by incorporating starch,carrageenan,nanocellulose(NC),Aloe vera,and hibiscus flower extract.The effects of varying the matrix composition(26.5–73.5 wt.%starch/carrageenan),NC concentration(2.77-17.07 wt.%),and particle type(fibers or crystals)on the film structure and characteristics were analyzed using various methods.Scanning electron microscopy demonstrated good homogeneity and effective dispersion of NC within the blendmatrix.An increased carrageenan content in the filmimproved wettability,moisture absorption,solubility,and water vapor permeability.The mechanical properties of the films were enhanced by NC incorporation and higher carrageenan content.The developed films also exhibited effective UV radiation barriers and biodegradability.Films with low carrageenan content(less than 33.3%)and high NC content(7%,10% crystals or 10%,15% fibers)exhibited optimal properties,including enhanced water resistance,hydrophobicity,and mechanical strength,along with reduced water vapor permeability.However,the high water solubility and moisture absorption(above 55% and 14%,respectively)indicated their unsuitability as packaging materials for food products with wet surfaces and high humidity.The results suggest that these films are well suited for use as edible food packaging for fruits and vegetables.

文摘The global demand for renewable and sustainable non-petroleum-based resources is rapidly increasing.Lignocellulosic biomass is a valuable resource with broad potential for nanocellulose(NC)production.However,limited studies are available regarding the potential toxicological impact of NC.We provide an overview of the nanosafety implications associated mainly with nanofibrillated cellulose(CNF)and identify knowledge gaps.For this purpose,we present an analysis of the studies published from 2014 to 2025 in which the authors mention aspects related to toxicity in the context of packaging.We also analyze the main methods used for toxicity evaluations and the main studies about toxicity evaluation using different biomarkers for a broad interpretation.This comprehensive biblio-graphic review highlights the critical need for further research to elucidate the mechanisms fully underlining NC toxicity,mainly due to its nanofibrillar structure.We focus on the cellular responses across different evaluated cell types through in vitro evaluation,always within the context of the dose used,the type of material or its source,and the type of biomarkers used in the assessments.The importance of addressing safety considerations and key knowledge gaps for the responsible use of CNF derived fromlignocellulosic biomass and its bionanocomposites in food packaging is highlighted.

文摘Walnuts are rich in a variety of nutritional components.However,due to their high content of unsaturated fatty acids(UFAs),the quality of walnuts tends to decline during storage,which adversely affects the development of the walnut industry.This study was aimed to investigate the impacts of temperature and packaging methods on the storage quality and oxidative stability of walnuts.The Wen 185 walnut variety was selected,and the physical-chemical and nutritional indexes of walnuts stored for 42 weeks under different temperatures(18℃,4℃,and room temperature)and packaging methods(vacuum light-exposed,vacuum light-proof,vacuum-ra-diation light-exposed,vacuum-radiation light-proof,nitrogen-filled light-exposed,nitrogen-filled light-proof)were measured.The results showed that low temperatures,especially18℃,in combination with vacuum lightproof packaging,could effectively suppress the increase in oxidative stability indicators such as acid value(AV)and peroxide value(PV),and maintain high retention rates of nutritional indicators like tocopherol and phytosterol.This study has elucidated that low temperatures and appropriate packaging methods play the crucial roles in maintaining the quality and oxidative stability of walnuts during storage.It has provided comprehensive and valuable data support and theoretical basis for the scientific storage of walnuts,contributing to the devel-opment of the walnut industry and the guarantee of product quality.

文摘The continuous increase in petroleum-based plastic food packaging has led to numerous environmental concerns.One effort to reduce the use of plastic packaging in food is through preservation using biopolymer-based packaging.Among the many types of biopolymers,chitosan is widely used and researched due to its non-toxic,antimicrobial,and antifungal properties.Chitosan is widely available since it is a compound extracted from seafood waste,especially shrimps and crabs.The biodegradability and biocompatibility of chitosan also showed good potential for various applications.These characteristics and propertiesmake chitosan an attractive biopolymer to be implemented as food packaging in films and coatings.Chitosan has been tested in maintaining and increasing the shelf life of food,especially seafood such as fish and shrimp,and post-harvest products such as fruits and vegetables.In addition to its various advantages,the properties and characteristics of chitosan need to be improved to produce optimal preservation.The properties and characteristics of chitosan are improved by adding various types of additive materials such as biopolymers,plant extracts,essential oils,and metal nanoparticles.Research shows that material additives and nanotechnology can improve the quality of chitosan-based food packaging for various types of food by enhancing mechanical properties,thermal stability,antimicrobial activity,and antioxidant activity.This review provides a perspective on the recent development and properties enhancement of chitosan composite with additives and nanotechnology,as well as this material’s challenges and prospects as food packaging.

文摘Growing environmental concerns and the need for sustainable alternatives to synthetic materials have led to increased interest in bio-based composites.This study investigates the development and characterization of sustainable egg packaging waste(EPW)biocomposites derived from recycled wood fibers and fungal mycelium filaments as a natural binder.Three formulations were prepared using EPW as the primary substrate,with and without the addition of hemp shives and sawdust as co-substrates.The composites were evaluated for granulometry,density,mechanical strength,hygroscopic behavior,thermal conductivity,and fire performance using cone calorimetry.Biocomposites,composed exclusively of egg packaging waste,exhibited favorable fire resistance,lower total heat release(THR)and total smoke release(TSR),extended time to ignition(TTI),reduced hygroscopicity,and higher flexural strength.Biocomposites,containing hemp shives,demonstrated improved compressive strength and thermal insulation but showed weaker fire resistance.Biocomposites,incorporating sawdust,showed intermediate properties with the longest flameout time(TTF)and highest heat release values.Overall,the results demonstrate that EPW-based biocomposites can be tailored through substrate composition to achieve desirable combinations of mechanical,thermal,and fire-retardant properties,highlighting their potential as sustainable alternatives to conventional syntheticmaterials in building and packaging applications.
