“…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). Lauroyl arginate ethyl (LAE) is considered as one of the most potent antimicrobial substances among novel food additives with strong and fast antimicrobial properties against foodborne pathogens in direct contact with them (Becerril, Manso, Nerin, & Gomez-Lus, 2013).…”

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.

“…Las investigaciones relacionadas con las interacciones empaque/alimento se están orientando en aprovechar las capacidades de migración de los materiales de empaque para obtener migraciones deseables con fines específicos, con los llamados "empaques activos", en los que el agente activo puede hacer parte del material de empaque desde su proceso de elaboración o adicionarse en forma individual haciendo parte del contenido del empaque; a esto se le conoce como migración positiva [42]. Los últimos desarrollos en empaques activos incluyen disminuir la velocidad de oxidación, crecimiento microbiano, y respiración.…”

ResumenLa calidad e inocuidad de los productos alimenticios es un tema relevante que involucra el comportamiento de los empaques en los procesos de preparación y almacenamiento de alimentos. En este contexto, el cumplimiento de la legislación alimentaria, cada día más exigente, requiere el conocimiento de varios aspectos clave en los sistemas empaque-alimento. Este artículo presenta una revisión acerca de los principales materiales de empaque actualmente usados en la industria alimentaria, sus interacciones con el producto empacado principalmente la migración de macro y microelementos desde el empaque hacia el alimento, abordando técnicas analíticas y modelos matemáticos usados en la identificación de elementos migrantes, así como también aspectos relacionados con la normativa establecida nacional e internacionalmente.

“…One of the most innovative and powerful antimicrobial compounds, not showing much of these drawbacks, is Ethyl-Nαdodecanoyl-L-arginate (LAE). LAE is a derivative of lauric acid, L-arginine and ethanol, which showed an extensive spectrum of antimicrobial activity against Gram positive and Gram-negative bacteria, as well as yeasts and molds (Infante et al, 1997;Bakal and Diaz, 2005;Pezo et al, 2012). It interacts, as a cationic surfactant, on the cytoplasmic membrane of microorganisms increasing the cell permeability without causing lysis (Nerin et al, 2016).…”

Sustainable Active PET Films by Functionalization With Antimicrobial Bio-Coatings

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.
