Swan-feathers inspired smart-responsive sustainable carboxymethyl cellulose/polyvinyl alcohol based food packaging film for robustly integrated Intelligent and Active Packaging

The integration of advanced packaging technology with innovative multifunctional bio-based materials emerges as a promising next-generation strategy to tackle two enduring challenges in food storage technology: food spoilage and counterfeiting. Inspired by the superhydrophobic properties of swan feathers, this study developed a smart-responsive, sustainable food packaging film called C-CPQ using carboxymethyl cellulose (CMC) and polyvinyl alcohol (PVA). The as-prepared C-CPQ film exhibited remarkable hydrophobicity and water-vapor barrier properties owing to its novel design featuring an asymmetric bionic feather-like barbed texture, representing significant advancements in CMC/PVA-based packaging materials. Additionally, C-CPQ exhibited satisfactory mechanical strength, biodegradability, and film-forming capabilities. Notably, incorporating quercetin（QR） endowed C-CPQ with exceptional pH-sensing, fluorescence, antioxidant, UV-shielding, and antibacterial properties, enabling intelligent and active food packaging. Consequently, C-CPQ exhibited UV-stimulated photochromic characteristics and fatigue-resistant food anti-counterfeiting capabilities while extending food shelf life to 5 days, surpassing conventional PE packaging by 2 days. Moreover, the integration of smartphones enabled highly sensitive, rapid, and real-time visual monitoring of food degradation under natural light. The findings of this study present promising outcomes under real-world conditions, serving as a framework for the development of sustainable, high-performance modern food packaging with comprehensive real-time visual freshness monitoring, anti-counterfeiting, and preservation functionalities.

Preparation and characterization of dialdehyde starch-soybean protein isolate stabilized carvacrol emulsion composite films

In order to reduce the harm of “petroleum-based plastics” with the problem of health and environment, the emulsion composite films with carvacrol nano-emulsions as antibacterial agent and polyvinyl alcohol (PVA) as matrices were prepared via the solvent-casting method. The average particle size of nano-emulsions was 175 nm with PDI value being 0.240. The transmittance of the emulsion composite films was close to zero in the UV-B region, with obvious UV barrier performance. The DPPH free radical scavenging rate was 60.96%, and the inhibition zone of the film forming emulsions was (21.5 ± 0.87) mm for S.aureus and (26.8 ± 1.01) mm for E.coli. Compared with the pure PVA film, the tensile strength and the water contact angle of the emulsion composite films were improved, the water vapor permeability was decreased by 28.7%. X-ray Diffraction and Fourier Transform Infrared Spectroscopy results showed the successful introduction of carvacrol nano-emulsions without a changeable structure. Therefore, the emulsion composite films have shown obvious application potential as packaging materials in modern food packaging.

Biocompatibility and Antimicrobial Profile of Acid Usnic-Loaded Electrospun Recycled Polyethylene Terephthalate (PET)-Magnetite Nanofibers.

The highest amount of the world's polyethylene terephthalate (PET) is designated for fiber production (more than 60%) and food packaging (30%) and it is one of the major polluting polymers. Although there is a great interest in recycling PET-based materials, a large amount of unrecycled material is derived mostly from the food and textile industries. The aim of this study was to obtain and characterize nanostructured membranes with fibrillar consistency based on recycled PET and nanoparticles (Fe3O4@UA) using the electrospinning technique. The obtained fibers limit microbial colonization and the development of biofilms. Such fibers could significantly impact modern food packaging and the design of improved textile fibers with antimicrobial effects and good biocompatibility. In conclusion, this study suggests an alternative for PET recycling and further applies it in the development of antimicrobial biomaterials.

Dual natural antioxidant‐loaded chitosan‐graft‐oleic acid micelles by ultrasound‐assisted self‐assembly: Potential additives for antioxidant active packaging

AbstractNatural antioxidants are beneficial additives for active packaging due to their ability to resist oxidative damage. Polymeric micelles are effective in delivering natural antioxidants in aqueous environments. However, individual encapsulation of a single antioxidant may not be sufficient to meet the needs of modern food packaging. A dual natural antioxidant‐loaded micellar system (i.e., vitamin E [VE] and curcumin [Cur]) was developed to achieve combined functionality and high loading concentration. Chitosan‐graft‐oleic acid (CSOA) micelles were employed as carriers to co‐encapsulate VE and Cur through a facile ultrasound‐assisted self‐assembly method. The prepared VE and Cur co‐loaded micelles (CSOA/VE/Cur) exhibited a uniform spherical structure with an average particle size of 210.6 nm and a zeta potential of +29.5 mV. Moreover, the co‐encapsulation of VE and Cur showed a significant enhancement in both entrapment efficiency, loading capacity and stability as compared to the individual encapsulation of either VE or Cur. In addition, the CSOA/VE/Cur micelles showed improved antioxidant activity than free VE/Cur at the same concentrations, as evidenced by 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays. Moreover, the micellar materials were utilized to fabricate regenerated cellulose (RC) films with antioxidant properties, highlighting their potential as additives for antioxidant active packaging.

Biocompatible green technology principles for the fabrication of food packaging material with noteworthy mechanical and antimicrobial properties-- A sustainable developmental goal towards the effective, safe food preservation strategy

Biocompatible, eco-friendly, highly economical packaging methods should be needed as conventional packaging is known to cause undesirable effects. As food packaging is the major determining factor of food safety, the selection or methods of packaging materials plays a pioneering role. With this scope, modern food technology seeks unique sustainable approaches for the fabrication of package materials with notable desired properties. The principles, features, and fabrication methodology of modern food packaging are briefly covered in this review. We extensively revealed improved packaging (nanocoating, nanolaminates, and nano clay), active packaging (antimicrobial, oxygen scavenging, and UV barrier packaging), and intelligent/smart packaging (O2 indicator, CO2 indicator, Time Temperature Indicator, freshness indicator, and pH indicator). In particular, we described the role of nanomaterials in the fabrication of packaging material. Methods for the evaluation of mechanical, barrier properties, and anti-microbial assays have been featured. The present studies suggest the possible utilization of materials in the fabrication of food packaging for the production, utilization, and distribution of safe foods without affecting nutritional values.

Using Africa’s past to promote change toward safer alternatives for food packaging in Accra

This study aimed at promoting attitude change among street vendors and their customers by exposing them to a communication intervention. The respondents were exposed to digitized images of ancient pottery and materials used to meet daily needs of food storage in Africa’s past, followed by a narration of how these materials were used in the past that could be used in the present day to package food. Respondents reflected on their experiences in the communication intervention and were engaged in a focus group discussion and in-depth interviews to tap their perceptions and intentions about safer alternative practices of food storage in the present times. To discourage the use of harmful food packaging products, respondents called for attitudinal changes among all actors and suggested that government interventions, prudent economic practices, and education about food packing practices should lead to the adoption of cultural packaging practices that are safe and enhances food quality, taste, and its palatability. Respondents further indicated that, innovative strategies aimed at transforming traditional packaging practices will add the modern touch and make traditional and cultural food packaging safer and acceptable. Thus, the use of earthenware, calabash, leaves, and pottery should be innovatively designed to be more portable and convenient for packaging food. Modern food packaging businesses should therefore explore the combination of knowledge and ideas from the past and the present to make food packaging safe and more environmentally friendly.

Eastern Poland Consumer Awareness of Innovative Active and Intelligent Packaging in the Food Industry: Exploratory Studies

For some time, traditional food packaging has not been able to meet the current market demand in some segments. This is mainly due to the advancing market globalization, increasing product complexity, the changing and increasingly high expectations and needs of customers, increasing requirements for monitoring packaging materials and, consequently, food safety, as well as the revival of national and international initiatives to support the circular economy and minimize the carbon footprint of manufactured products. Therefore, smart packaging with increased functionality has become indispensable. On the one hand, this solution allows for the offering or adaptation of products that meet the stricter national and international regulatory requirements (in particular for food safety) and allows a tracking from the cradle to the grave; on the other hand, it can serve as a way to expand markets in the context of globalization. Moreover attention should be paid to the development of knowledge on environmental protection and the increasing environmental awareness of consumers. In connection with the above, in recent years there has been an increase in interest in the design and production of new packaging for food products based on the latest technical and technological solutions. It is primarily intelligent and active packaging that should be mentioned here. Hence, the aim of the article, as well as that of our own conducted research, was to analyze consumer attitudes and behaviors in the field of modern food packaging, as well as to check the level of awareness of consumers from Eastern Poland in relation to innovative active and intelligent packaging in the food industry. In addition, the intermediate aim was also to identify other factors influencing the attractiveness of food packaging and, consequently, increasing the willingness to buy them. To achieve these aims, a literature study was carried out, as well as empirical research using the diagnostic survey method, conducted among the inhabitants of South-Eastern Poland. Based on our own research, it can be concluded that the level of knowledge of the essence of intelligent and active packaging in Eastern Poland is still at a low level. Among the other factors increasing the attractiveness of packaging for food products, contemporary consumers from the analyzed region of Poland indicated primarily their environmental friendliness, the possibility of recycling, as well as the readability and transparency of the information contained on the packaging.

Analytical Approaches for Analysis of Safety of Modern Food Packaging: A Review.

Nowadays, food packaging is a crucial tool for preserving food quality and has become an inseparable part of our daily life. Strong consumer demand and market trends enforce more advanced and creative forms of food packaging. New packaging development requires safety evaluations that always implicate the application of complex analytical methods. The present work reviews the development and application of new analytical methods for detection of possible food contaminants from the packaging origin on the quality and safety of fresh food. Among food contaminants migrants, set-off migrants from printing inks, polymer degradation products, and aromatic volatile compounds can be found that may compromise the safety and organoleptic properties of food. The list of possible chemical migrants is very wide and includes antioxidants, antimicrobials, intentionally added substances (IAS), non-intentionally added substances (NIAS), monomers, oligomers, and nanoparticles. All this information collected prior to the analysis will influence the type of analyzing samples and molecules (analytes) and therefore the selection of a convenient analytical method. Different analytical strategies will be discussed, including techniques for direct polymer analysis.

Histamine Formation in a Dry Salted Twaite Shad (Alosa fallax lacustris) Product

Landlocked shad is a freshwater clupeid fish ( Alosa fallax lacustris ) whose consumption is associated with the risk of scombrotoxin poisoning. Traditionally, fresh shad are subjected to an artisanal processing procedure, consisting of dry salting and maturation under pressure, to give a fish product named missoltino , which is stored in large metallic barrels and is sold to local consumers and restaurants. In recent years, the introduction of modern food packaging technologies has enabled this product to also be distributed in shops and supermarkets. Consequently, the determination of the safety of this product is an urgent issue. The aims of the present research were to measure histamine levels and histamine-forming bacteria in shad products collected at different phases of preparation and ripening, in order to minimize poison hazards, to provide technical information about risk, and to standardize the production process. One hundred twenty-six samples of shad (21 fresh fish and 105 dried) at different phases of preparation and ripening were collected from seven producers and were analyzed for chemical composition, histamine content, and microbiological properties. After 130 days of ripening, samples from three producers presented unacceptable amounts of histamine (>200 mg/kg), according to European Union legislation. A moderate negative correlation was found between histamine levels and salt content (r =-0.504, P < 0.01) and between histamine levels and water phase salt content (r =-0.415, P < 0.01). Several bacterial strains that were positive on Niven's medium were isolated during the early phases of production, whereas the extreme environment of salted shad at the end of ripening led to a drastic decrease of bacteria, but not of histamine. The most effective preventive measures for histamine formation and accumulation in salted shad were strictly related to fish handling and storage conditions during processing.

Machine-coated starch-based dispersion coatings prevent mineral oil migration from paperboard

Abstract Mineral oil migration through paperboard presents a safety risk in modern food packaging. This study aimed to enhance the safety of fiber-based packaging by utilizing a bio-based composite barrier layer to protect against mineral oil. Starch-clay composite coatings on paperboard were created via dispersion coating. Thermal analysis of the coating components and field emission scanning electron microscopy imaging were performed to ascertain the physicochemical properties and morphology of the coatings. Coating functionality was evaluated using contact angles and transmission rate (water and oxygen) measurements. The packaging safety focus was implemented by measuring the gas phase migration of heptane and analyzing the migration of liquid mineral oil through the coated paperboards with FTIR. The functional properties of the coated paperboards were maintained or improved. The studied coatings were effective barriers against the migration of mineral oil and could hence improve the barrier properties and safety of fiber-based primary food packaging.

Photonics and nanophotonics and information and communication technologies in modern food packaging.

The analysis of the problem of conjunction of information and communication technologies (ICT) with packaging industry and food production was made. The perspective of combining the latest advances of nanotechnology, including nanophotonics, and ICT for creating modern smart packaging was shown. There were investigated luminescent films with zinc oxide nanoparticles, which change luminescence intensity as nano-ZnO interacts with decay compounds of food products, for active and intelligent packaging. High luminescent transparent films were obtained from colloidal suspension of ZnO and polyvinylpyrrolidone (PVP). The influence of molecular mass, concentration of nano-ZnO, and film thickness on luminescent properties of films was studied in order to optimize the content of the compositions. The possibility of covering the obtained films with polyvinyl alcohol was considered for eliminating water soluble properties of PVP. The luminescent properties of films with different covers were studied. The insoluble in water composition based on ZnO stabilized with colloidal silicon dioxide and PVP in polymethylmethacrylate was developed, and the luminescent properties of films were investigated. The compositions are non-toxic, safe, and suitable for applying to the inner surface of active and intelligent packaging by printing techniques, such as screen printing, flexography, inkjet, and pad printing.

Cytotoxicity and mutagenicity assessment of organomodified clays potentially used in food packaging

Modern food packaging has made great advances as result of global trends and consumer preferences, which are oriented to obtain improved food quality and safety. In this regard, clay minerals, and mainly Montmorillonite (Mt) are attracting considerable interest in food packaging because of the improvements developed in mechanical and barrier properties. Hence, the present work aim to assess the toxicity of four Montmorillonite-based clay minerals, an unmodified clay, Cloisite®Na+ (CNa+), and three modified Mt clays: Cloisite®30B (C30B), a commercial clay, and Clay1 and Clay2, two novel modified organoclays developed by the Packaging, Transport, & Logistics Research Institute (ITENE). First, the cytotoxic effects were studied in the Human Umbilical Vein Endothelial Cells (HUVEC). In addition, the potential mutagenicity of the clays was evaluated by the Ames test. Clay1 did not induce any cytotoxic effects in HUVEC, although it exhibited potential mutagenicity in TA98 Salmonella typhimurium strain. In contrast, Clay2 produced cytotoxicity in endothelial cells but no mutagenicity was recorded. However, CNa+ was not cytotoxic neither mutagenic. And finally, C30B showed positive results in both assays. Therefore, results showed that clay minerals have a different toxicity profile and a case by case toxicity evaluation is required.

Newly Developed Starch-Based Hydroxyethyl Cellulose Film with Wide Spectrum of pH-Colour Indicator

Active packaging is a promising form of modern food packaging with great potential; economically, environmentally and generally, as it gives a lot of health benefits. Active and smart packaging is made by incorporating suitable colour indicators into food package matrices and applying a bio switch concept to inhibit the spoilage and the pathogenic microorganisms. The main objective of this study are to evaluate starch-based hydroxyethyl cellulose (HEC) the best formulation of methyl red and bromothymol blue that can react with wide pH ranges and the effect of the smart film indicator incorporated with methyl red and bromothymol blue. A solution casting method was used in the film preparation and colour indicators were incorporated before casting. The ratio of 50:50 methyl red and bromothymol blue showed the best formulation which can react with a wide range of pH buffer 1 to 13 compared to ratio 20:80 and 80:20 of methyl red and bromothymol blue. The ratio of 50:50 methyl red and bromothymol blue were then selected to be incorporated into the film to see the effectiveness of the indicator film in order to detect the changes of pH.
