Special Issue Information

Dear Colleagues,

Novel and emerging technologies in food packaging are a trending area of research to boost food quality and safety in recent years. Packaging that is both environmentally friendly and edible is becoming more popular. To reduce waste and keep food fresh, edible packaging uses biodegradable materials that are applied as a consumable coating or wrapping around the food. Various recent studies have examined the value of edible components as an additional benefit to packaged foods. Nanotechnology is increasingly looking like a potential area to use bioactives, antimicrobials, vitamins, and antioxidants to produce edible packaging more useful, so it can be promoted as a component of edible and green coatings and films such as nanofibers, nanocapsules, nanoparticles, and nanoemulsions.

An active packaging system plays an important part in packaged foods by engaging with the food, such as releasing antimicrobial and antioxidant compounds and attempting to remove harmful gases such as oxygen and water vapor, preventing as a result the reduction in food quality and shelf life. Additionally, the nutritional profile of packaged foods can also be preserved through the use of active packaging.

Smart/Intelligent packaging should be able to sense or measure the characteristics of products, the inside condition of a package, or the transportation environment. Microelectronics, computers, and nanotechnology are all examples of advanced packaging systems that utilize such terminology. Intelligent packaging systems are described in three main aspects: barcode systems designed mainly for storage, delivery, and traceability; the use of indicators in the food supply chain that deliver qualitative data on quantities collected in real time; and sensors for the measurement of analytes for the evaluation of food quality and package integrity.

Novel technological advances in food packaging will provide an active role in future applications to preserve foods.

Original articles or reviews including, but not limited to, the following topics are welcome:

  • Active and smart/intelligent packaging;
  • Biodegradable coatings and materials;
  • Edible films;
  • Antimicrobial coatings and films;
  • Different coating technologies and materials;
  • Novel and emerging technologies for food preservations;
  • Nanotechnology research for packaging materials.

Biopolymer-based films were developed using a mixture of pullulan and agar, and the fabricated film was functionalized with bioactive functional components, Pickering emulsion of eucalyptus essential oil (PEU), and rutin. The color of the film with PEU and rutin supplemented was light yellow. As a result, the yellowness index increased while the whiteness index of the film reduced. The functional filler showed a biocompatibility with the pullulan/agar polymer matrix. The presence of bioactive functional materials enhanced the UV protection properties of the film. The films’ mechanical properties, vapor barrier properties, and thermal stability were not pointedly affected by the presence of essential oils and rutin alone or in combination. The presence of essential oils and rutin markedly enhanced the antioxidant activity of pullulan/agar-based films. Therefore, the bioactive functional film developed can be useful for active food packaging applications. Full article

In this study, the shelf life of fresh-cut iceberg lettuce (Lactuca sativa L.) was evaluated. Lettuce samples were washed with disinfectant agents and sodium hypochlorite and then soaked in an ascorbic acid solution. Next, samples were stored in packaging films containing three levels (1% and 3% and 0% as a control film) of nano-bentonite particles (NBPs) as a filler in a modified atmosphere for 12 days at 4 °C. Various physicochemical parameters such as color, texture, pH, titratable acidity, dehydration, moisture, dry matter, chlorophyll content, microbial quality, and sensory properties were investigated. Results indicated that nano-packaging had a significant ability to maintain the sensory physicochemical properties of lettuce at the fifth (1% nano-composite film) and ninth (3% nano-composite film) days of storage when compared to the control films. The greatest growths of molds and yeasts were observed in the control films, which demonstrates the effectiveness of the application of bentonite nanoparticle fillers. Full article
