“…Water vapour transmission rate (WVTR) was performed according to DIN 53122-1 and ISO 2528:1995 norms as described elsewhere [ 49 ]. WVTR was measured by means of a gravimetric method that is based on the sorption of humidity by CaCl 2 and a comparison of sample weight gain.…”

Preparation of biodegradable packaging materials and valorisation of food industry residues to achieve “zero waste” goals is still a major challenge. Herein, biopolymer-based (carboxymethyl cellulose—CMC) bioactive films were prepared by the addition, alone or in combination, of carvacrol and fungal melanin isolated from champignon mushroom (Agaricus bisporus) agro-industrial residues. The mechanical, optical, thermal, water vapour, and UV-Vis barrier properties were studied. Fourier-transform infrared (FT-IR) spectroscopy studies were carried out to analyse the chemical composition of the resulting films. Antibacterial, antifungal, and antioxidant activities were also determined. Both CMC/melanin and CMC/melanin/carvacrol films showed some antimicrobial activity against Escherichia coli, Staphylococcus aureus, and Candida albicans. The addition of melanin increased the UV-blocking, mechanical, water vapour barrier, and antioxidant properties without substantially reducing the transparency of the films. The addition of carvacrol caused loss of transparency, however, composite CMC/melanin/carvacrol films showed excellent antioxidant activity and enhanced mechanical strength. The developed bioactive biopolymer films have a good potential to be green bioactive alternatives to plastic films in food packaging applications.

“…In general, an active coated packaging material or packaging material containing antimicrobial agents incorporated into the polymer matrix should function during storage to inhibit microorganism growth to extend the shelf-life of the food product and maintain its quality. This means that the coatings and active films should offer sufficient resistance against ultraviolet (UV) radiation or be shielded against UV [90][91][92]. UV radiation is a part of the nonionizing region of the electromagnetic spectrum that comprises approximately 8-9% of total solar radiation.…”

“…As a result of nanotechnology development, ZnO nanoparticles have been incorporated into the matrix of many polymers or many coating carriers to obtain active layers to enhance the properties of such films/coatings without significant influence on their transparency. Additionally, these nanoparticles have attracted great interest and the development of coating/film applications as agents to improve Overview of Food Antimicrobial Packaging DOI: http://dx.doi.org/10.5772/intechopen.108666 anticorrosion properties has increased, particularly as UV absorbers [90][91][92]. Many studies demonstrated that ZnO nanoparticles exhibited superior chemical stability under UV radiation compared to other UV absorbers [47][48][49]93].…”

“…The negative influence of UV-aging on the chemical composition of the coatings due to the presence of ZnO nanoparticles was not observed. Another example can be PLA films which were covered with an MHPC/cocoa butter carrier, containing Eucomis comosa extract as an active, antimicrobial agent [91]. The covered, active films were treated with accelerated UV-A and Q-SUN irradiation.…”

Acutely due to awareness that food products are highly vulnerable to microbial contamination, the food industry constantly tries to uncover new methods for the preservation of their products in order to guarantee their goods and processes continue to offer the highest quality and uphold safety standards throughout the production, storage, and distribution chain. Antimicrobial food packaging can play an important role in food shelf-life extension through the inhibition of microorganism growth present on the surface of food products. Antimicrobial packaging materials containing active substances incorporated into a polymer matrix or as surface coatings have begun to receive more attention for their use as antimicrobial control agents in food packaging systems. The most commonly used packaging materials are paper and plastics. However, from the ecological point of view, biopolymer-based materials have recently garnered more attention in the development of antimicrobial packaging as an alternative, due to their nontoxic biodegradability. In addition, the ongoing global spread of the pandemic caused by the SARS-CoV-2 has led to a preference for fresh food packaged in single-use food coverings. In order to address customer concerns and safeguard their health, the packaging industry could implement additional health safety measures, such as active packaging with antiviral properties.

“…In this regard, the antimicrobial properties and water vapor performance of PLA films coated with a cellulose derivative/cocoa butter carrier incorporating Eucomis comosa extract as an active substance have been investigated [18]. The coatings reduced the water vapor permeability of the biopolymer and provided improved resistance against UV-aging, which is desirable to extend the shelf life, quality and freshness of food products.…”
