“…The absence of changes in the intensities and positions of the major CS and GL bands suggests a low interfacial interaction between these biopolymers and the LAE. Similar results were reported by Gaikwad et al (2017) and Rubilar et al (2016).…”

“…Active packaging or enrichment of packaging materials with certain additives is an innovative concept to improve food safety and quality (Gaikwad, Lee, Lee, & Lee, 2017). The capacity to release the active compound in a progressive way is an obvious advantage over conventional packaging systems in which the full amount of active agent is added in the food formulation (Pezo, Navascués, Salafranca, & Nerín, 2012).…”

Blend and bilayer bio-based active films were developed by solvent casting technique, using chitosan (CS) and gelatin (GL) as biopolymers, glycerol as a plasticizer and lauroyl arginate ethyl (LAE) as an antimicrobial compound. Blend films had higher tensile strength and elastic modulus and lower water vapor permeability than bilayer films (p < 0.05). Bilayer films demonstrated as effective barriers against UV light and showed lower transparency values (p < 0.05). FT-IR spectra indicated that interactions existed between CS and GL due to electrostatic interactions and hydrogen bond formation. However, the addition of LAE did not interfere in the network structure. Active films incorporated with LAE (0.1%, v/v) inhibited the growth of Listeria monocytogenes, Escherichia coli, Salmonella typhimurium and Campylobacter jejuni. This study highlighted the development of blend and bilayer bio-based active films based on CS and GL enriched with LAE for food packaging applications with improved physical, mechanical, barrier and antimicrobial properties.

“…The absence of changes in the intensities and positions of the major PLA and LAE bands suggests the realization of a physical mixture, with no chemical interaction between the two phases. Similar results were also reported by other authors (Rubilar et al, 2016;Gaikwad et al, 2017).…”

Sustainable Active PET Films by Functionalization With Antimicrobial Bio-Coatings

et al. 2019

The realization of antimicrobial films through the incorporation of active agents into a polymer matrix is a promising alternative to the direct addition of antimicrobials into the food matrix. To this aim, the goal of this work was to develop a sustainable, food packaging solution with antimicrobial effectiveness and high functional performance, based on Ethyl-Nα-dodecanoyl-L-arginate (LAE). Active biodegradable coatings, easy soluble to be removed, were realized by spreading a Polylactic acid/LAE coating solution, at different antimicrobial concentration (from 0 to 20%), on a recyclable Polyethylene-terephthalate substrate. The antimicrobial activity of the multilayer films was tested in vitro against E.Coli CECT 434 strain as pathogenic agent in liquid culture media. Moreover, the LAE chemical interaction with the PLA matrix was investigated, as well as its effect on the adhesion, wetting, optical and barrier properties of the films. The results pointed out that that the minimum LAE concentration incorporated already guarantees an antimicrobial activity comparable to commercial antimicrobial packaging solutions, and that, among the systems investigated, 10% LAE is the minimum concentration guaranteeing total inhibition without significantly altering the functionalities of the developed systems.

“…In principle, ethylene scavenging systems comprise either inclusion of a small sachet containing an appropriate scavenging agent in the packaging or incorporation of an ethylene scavenger in the packaging material structure. The sachet material should be highly permeable to gaseous ethylene, allowing diffusion through it (Yildirim et al 2018;Gaikwad et al 2017a). Effective ethylene scavenger can be further divided into two main categories: ethylene absorbers and scavengers; absorbers are those materials who physically absorb and hold ethylene molecule from the surrounding environment, and on the other hand, ethylene scavenger, where water absorption is by means of a chemical reaction between two materials (Vilela et al 2018).…”

“…It is a volatile compound of enormous significance as a plant hormone. This hormone formed by higher plants activates and hence controls physiological mechanisms, development, regulating growth, ripening and senescence aspects of plants (Zhu et al 2019;Gaikwad and Lee 2017a). Ethylene produces physiological responses, for example geotropism, ripening, senescence, dormancy and flowering (Singh et al 2018a, b, c, d).…”

Many fruits and vegetables are sensitive to ethylene, which upon prolonged exposure induces the deterioration of food quality, such as change in taste, odour and colour, or microbial growth. Therefore, ethylene scavengers in packages can be used to limit ethylene accumulation. Ethylene scavengers extend the shelf life and retain the original food quality. Here, we review ethylene scavenging systems such as potassium carbonate, palladium, natural clays, titanium dioxide-based, electrondeficient dienes and trienes. Ethylene scavenging is done by chemical reactions and physical adsorption. We then discuss the applications and benefits of ethylene scavengers in packages. The efficiency of ethylene scavengers is improved using atmospheric packaging tools.
