Special Issue Information

Dear Colleagues,

The development of sustainable food value chains relies on improvements in production, aggregation, processing, storage, and distribution. In particular, the storage and distribution of plant- and animal-derived foods (minimally, moderately, and highly processed) are known to be essential parts of the food value chain. Therefore, increased attention has been given to the development of sustainable food packaging. In addition, lowering waste from packaging has also taken priority due to environmental concerns. Various types of micro and nanomaterials are being developed for food packaging applications that mainly focus on the control of water activity and temperature, as well as the incorporation of bioactive agents (antimicrobial or antioxidant activities). The other major areas of interest include the safety assessment of food products and food packaging. This is because fillers such as nanoparticles or chemical constituents can migrate from packaging (nanocomposite) to food products.

We invite authors to submit original research articles, reviews, and viewpoint articles related to the global efforts being made to improve all aspects of food packaging. We are also interested in articles that focus on materials (matrices and fillers), processes, value chains, and technologies, which can have a considerable impact on food safety. Topics of interest include but are not limited to:

  • Novel nanocomposites;
  • Polymeric nanoparticles;
  • Metallic nanoparticles;
  • Cost-effective and eco-friendly packaging;
  • Novel micro and nanomaterials;
  • Micro and nanoplastics;
  • Nanosensors;
  • Plant- and animal-derived food packaging.

Abstract
In this study, an antimicrobial plant-based film was developed using pectin which is incorporated by different percentages of nanoemulsified trans-cinnamaldehyde (TC). The nanoemulsion of TC was incorporated into pectin to form films containing TC at concentrations of 5.00%, 3.33%, 2.50% and 2.00% [...] Read more.
In this study, an antimicrobial plant-based film was developed using pectin which is incorporated by different percentages of nanoemulsified trans-cinnamaldehyde (TC). The nanoemulsion of TC was incorporated into pectin to form films containing TC at concentrations of 5.00%, 3.33%, 2.50% and 2.00% (w/w). The nanoemulsion of TC was formed by using soybean lecithin as an emulsifier and had a zeta potential of −57 mV and an average size of 106 nm. The analysis showed that the addition of emulsified TC enhanced the light barrier properties, but the opacity of films increased due to the increase in light absorption, coalescence, and light-scattering phenomena. Films containing the nanoemulsion of TC exhibited reduced tensile strength and elasticity due to structural discontinuities in the film network caused by the presence of the nanoemulsion of TC, while elongation at break increased for TC concentrations of 2.50% and 2.00%. The films retained their infrared spectra, but their thermal stability decreased slightly. The incorporation of TC nanoemulsion significantly reduced the glass transition temperature, as shown by the differential scanning calorimetry analysis. The active films showed antimicrobial activity against Listeria innocua and Escherichia coli, indicating their potential for various food applications. Full article
