Special Issue Information

Dear Colleagues,

Packaging contributes to the preservation of food quality during transportation and storage while simultaneously eliminating the possible risks of the chemical contamination of food products and food-borne illnesses associated with the safety of food. Food coatings limit the contact of food with the environment, alter the functional properties of foods, and promote the control of the surface moisture of food. At present, the food industry mainly relies upon non-biodegradable and fossil-derived synthetic plastic materials for food packaging, which significantly contribute to environmental pollution. In recent years, a significant amount of research has been conducted and/or is in progress to reduce these environmental impacts, such as the development of innovative, sustainable materials and technologies towards improved food packaging and coatings.

This Special Issue addresses the recent progress and new developments in sustainable food packaging and coatings research. Please submit original research articles and reviews related to the following topics:

  • Recent progress in novel packaging, including active, intelligent, smart, biodegradable, compostable, recyclable, and/or reusable packaging research;
  • Advances in edible coatings for fresh produce;
  • Novel technologies for the surface modification of biodegradable polymers applied to food packaging (such as plasma technology);
  • Life cycle assessment (LCA) and techno-economic analysis (TEA) of novel packaging technologies;
  • Miscellaneous topics relevant to sustainable packaging and coatings.

We look forward to receiving your contributions!

Most cans intended to come into contact with food require the application of an internal coating made from synthetic polymers. The most widely used type of coating are epoxy resins based on bisphenol A diglycidyl ether (BADGE). It has been found that some components like cyclo-di-BADGE (CdB) and other BADGE derivatives can migrate into food. In this study, the polymeric coating of forty-eight cans was assessed using an infrared spectrometer with attenuated total reflectance. The food samples were extracted, and a targeted analysis was carried out to quantify CdB using liquid chromatography with fluorescence detection (HPLC-FLD). The first estimation of the exposure of the adult population was estimated by combining the concentration of CdB in the samples and the Spanish consumption data. In addition, a non-targeted screening by LC-MS was performed in the food sample extracts for the identification of other BADGE derivatives. Twenty samples were positive for the presence of CdB reaching concentrations of 2623 µg/kg. However, the tolerable daily intake of 1.5 µg/kg bw/day recommended for chemical compounds with high toxicological risk was not exceeded. A total of 18 epoxy oligomers could be tentatively identified in the food extracts being BADGE.H2O.BuEtOH the derivative with the highest incidence. Full article

The antimicrobial property is the key feature of active packaging. Biological macromolecules such as tannic and gallic acids are naturally found in plants such as tea, fruits, berries, and grapes. The incorporation of tannic acid (TA) and gallic acid (GA) in the biodegradable polymer blend Poly Lactide-Poly (Butylene Adipate-Co-Terephthalate) (PLA-PBAT) was used in this study to assess the potential of active packaging. TA and GA (10 wt%) composite films showed a 65%–66% increase in the UV barrier property. The tensile strength value increased after the incorporation of TA and GA (10 wt%), respectively. Overall, 1.67 and 2.2 log reductions in E. coli and L. monocytogenes growth were observed, respectively, in the presence of TA (10 wt%) composite film. In addition, TA composite film was able to maintain and enhance the quality of cherry tomatoes for up to 20 days of storage at room temperature. For cherry tomatoes packed in PLA-PBAT-TA10 (wt%), TSS decreased by 6.3%, pH was 4.3, and a microbial reduction of 2.70 log CFU/mL was observed. In conclusion, TA composite film had confirmed significant UV blocking properties, surface hydrophobicity, and antibacterial properties, which show its potential as an active packaging film.

The aim and the novelty of the present review article was to provide the literature with a collective study focusing on the migration and safety issues in plastic food packaging materials that have been raised in recent years and proposing the use of safer and biodegradable ones. The conventional packaging materials used for the preservation of foods may exhibit many disadvantages that are related to the migration of micromolecular chemical substances incorporated in the packaging material net to the packaged food. There are many chemical substances in the matrix of plastic packaging materials and epoxy-resins that are used in food packaging materials, varnishes, and can coatings. Many migrants have high toxicity, such as acetaldehyde, antimony, antimony (III) oxide, 2,4-di-tert-butylphenol, tris (2,4-di-tert-butylphenol) phosphate, tris(2,4-di-tert-butylphenyl) phosphite, bisphenol A, and the plasticizers di(2-ethylhexyl) phthalate), di-n-butyl phthalate, benzyl-butylphthalate, di-isononylphthalate, and di-isododecylphthalate. It is therefore necessary to take a detailed look at the migrants in conventional packaging materials (plastics) used for foods, point out the migration of certain compounds into foods and the need to reconsider their use, and establish updated protocols for the safety of consumers and the industrial production of biodegradable packaging materials (films or coatings) based on natural sources.

Nanotechnology plays a crucial role in food preservation, offering innovative solutions for food monitoring and enabling the creation of packaging with unique functional properties. The nanomaterials used in the packaging can extend the shelf life of foods, enhance food safety, keep consumers informed about contamination or food spoilage, repair packaging damage, and even release preservatives to prolong the durability of food items. Therefore, this review aims to provide an overview of the diverse applications of nanotechnology in food packaging, highlighting its key advantages. Safety considerations and regulations related to nanotechnology packaging are also addressed, along with the evaluation of potential risks to human health and the environment, emphasizing that this field faces challenges in terms of safety considerations and regulations. Additionally, the development of nanotechnology-based packaging can drive advancements in food preservation by creating safer, more sustainable, and higher-quality packaging. Thus, nanotechnology offers the potential to enhance the efficiency and functionality of packaging, delivering substantial benefits for both manufacturers and consumers. Full article

Cold plasma (CP) is an effective strategy to alter the limitations of biopolymer materials for food packaging applications. Biopolymers such as polysaccharides and proteins are known to be sustainable materials with excellent film-forming properties. Bio-based films can be used as an alternative to traditional plastic packaging. There are limitations to biopolymer packaging materials such as hydrophobicity, poor barrier, and thermos-mechanical properties. For this reason, biopolymers must be modified to create a packaging material with the desired applicability. CP is an effective method to enhance the functionality and interfacial features of biopolymers. It etches the film surface allowing for better adhesion between various polymer layers while also improving ink printability. CP facilitates adhesion between two or more hydrophobic materials, resulting in significantly better water vapour permeability (WVP) properties. The sputtering of ionic species by CP results in cross-linkage reactions which improve the mechanical properties of films (tensile strength (TS) and elongation at break (EAB)). Cross-linkage reactions are reported to be responsible for the improved thermal stability of CP-treated biopolymers. CP treatment is known to decrease oxygen permeability (OP) in protein-based biopolymers. CP can also enable the blending of polymers with specific antimicrobial substances to develop active packaging materials. In this review article, we have presented an overview of the recent advancements of CP in the food packaging application. Furthermore, the influence of CP on the properties of packaging materials, and recent advancements in the modification of polymeric food packaging materials have been discussed. Full article
