Special Issue Information

Dear Colleagues,

It is no doubt that the development of new materials for food packaging is a challenge that involves scientific and technological competences. Consumer needs and socioeconomic problems are the most important driving forces of this process that has, as its ultimate goal, the delivery of high-quality and safe food products to the consumer in an efficient manner.

Their use has been addressed toward two main perspectives: (a) modulating the gas exchange rate between the inside and outside of the package environment (such as some applications of modified-atmosphere packaging) and (b) actively controlling the release or absorption of specific compounds from the packaged food (active packaging). In particular, the possibility of tailoring the membrane morphology, porosity, and properties allows an extension of their use to a broad range of food packaging purpose. For this reason, food packaging and membrane developers have started collaborations in order to evaluate how membrane science could be applied to food packaging.

In this continuously evolving scenario, the design and production of innovative food packaging has fundamental importance, and membranes can play a key role and actively contribute to this innovation.

The aim of this Special Issue is to highlight beneficial outcomes of the research being performed  with regard to the application of membranes in controlling gas permeability, membranes in modified-atmosphere packaging, and membranes as devices for active food packaging in the development of environmentally friendly packaging materials with biodegradable properties. Both original research articles and review papers are welcome.

Nowadays, proteins and polysaccharides play a fundamental role in the manufacturing of biocompatible materials applied in food packaging. The resulting films have, however, limits associated with the resistance to mechanical stress; therefore, it is important to reinforce the initial mixture with additives that promote the development of stronger molecular links. Carbon dots (CDs) are excellent candidates for this purpose due to the presence of surface functional groups that determine the formation of numerous intramolecular bonds between the charged biopolymers. The present research aims to evaluate the effect of CDs on the mechanical properties of biopolymer films obtained from sodium caseinate (CAS), high methoxyl pectin (HMP) and glycerol used as plasticizers. Green carbon dots (gCDs) were obtained from natural organic sources by green synthesis. The effects of gCDs on the flow behavior and viscoelastic properties of mixed biopolymer dispersions and the thermophysical properties of the corresponded films were evaluated by steady and unsteady shear rheological measurements and differential scanning calorimetry (DSC) tests, respectively. The dynamic mechanical measurements were realized taking into account the parameters of temperature and relative humidity. The results indicate a significant change in the viscosity of the protein–polysaccharide dispersions and the thermomechanical properties of the corresponding film samples reinforced with higher amounts of gCDs.

This study aimed to develop active films based on carboxymethyl chitosan (CMCS)/locust bean gum (LBG) films containing Melissa officinalis L. essential oil (MOEO) nanoemulsions. The results showed that the active films incorporated with MOEO nanoemulsion resulted in an increase in the elongation of break, water resistance and improved the film hydrophilicity. Elongation of break increased from 18.49% to 27.97% with the addition of 4% MOEO nanoemulsion. Water resistance was decreased from 56.32% to 25.43%, and water contact angle was increased from 75.13 to 83.86 with the addition of 4% MOEO nanoemulsion. However, the water vapor barrier properties and tensile strength decreased with the addition of MOEO nanoemulsions. The scanning electron microscopic images and Fourier transform infrared spectroscopy results showed that the MOEO was very compatible with the film materials and dispersed evenly in the films. At the same time, the addition of MOEO nanoemulsion significantly enhanced antioxidant and antibacterial activities of C/L-MOEO films. The antioxidant and antimicrobial activities of C/L-MOEO films were increased from 7.16% to 33.81% and 3.52% to 54.50%, respectively. In general, C/L-MOEO film has great application prospects.
