“…The rolls that comprised approximately 100 m of film 173 Table 1 and Table 2). The increased AM agent concentration in this polymer mixture is 211 attributed to the lower processing temperature and to the interaction between the AM 212 agents and the copolymer enabling the "anchoring and solubilizing" of the AM molecules 213 within the polymeric matrix (Suppakul et al, 2008). 214…”

24Films based on linear low-density polyethylene (LLDPE) and low-density 25 polyethylene (LDPE) containing linalool or methylchavicol were prepared by extrusion 26 film blowing. Film rolls of LLDPE containing linalool or methylchavicol were stored at 27 ambient temperature for 1 year. Samples of these films were then evaluated for the 28 amount of linalool or methylchavicol retained and for their antimicrobial (AM) activity 29 by the agar disc diffusion assay. In addition, film rolls of LDPE-EVA (LDPE-ethylene 30 vinyl acetate) containing linalool or methylchavicol were stored at 25 and 35C. Samples 31 of these films were periodically collected to quantify the amount of linalool or 32 methylchavicol retained as a function of time. For the AM LLDPE films, a decrease in 33 additive retention was observed but there was no statistically significant difference in 34 their AM activity against E. coli at the beginning and after 1 year of storage. For the AM 35 LDPE-EVA films, the amount of additive in the film decreased with time and the additive 36 retention in all films tended to deviate from the theoretical first-order decay. These 37 findings suggest that an amount of linalool or methylchavicol that is sufficient to maintain 38 AM activity remained in the polymeric matrix after the storage period. This study 39 confirms the potential use of polymeric films containing basil constituents as AM films 40 for enhancing quality and safety as well as the extension of the shelf life of foods. 41 42

“…Usually, compounds with phenolic groups are most effective [5]. Although many studies have demonstrated the antimicrobial effect of essential oils and their active compounds against a broad spectrum of pathogenic bacteria in food [6] [7] [8], there are very few publications that discuss their incorporation as additives in packaging materials [9] [10] [11] [12] [13]. Given that the US Food and Drug Administration categorizes natural extracts such as essential oils (EOs) and their constituents as generally recognized as safe, packaging manufacturers and demanding consumers consider the incorporation of these natural extracts in plastic films an appealing way of avoiding microbial food spoilage [14].…”

“…In such systems, the active agents are supported or adsorbed on a solid matrix from which they are released to the atmosphere and act as food-protecting agents. Antimicrobial packaging, an innovative concept, can be defined as a kind of active packaging in which the package, the product, and the environment interact to reduce, inhibit, or retard the growth rate of microorganisms [11]. In these technologies, researchers are developing food packaging materials such as synthetic films [10] [11] [12] and edible films [16]- [22] with antimicrobial properties.…”

A simple and rapid Fourier Transform infrared (FTIR) spectroscopy method was developed to determine the main essential oil components (carvacrol, thymol and p-cymene) in the antimicrobial LDPE films incorporated with oregano and 1050 cm −1 -1017 cm −1 were respectively used for quantitative estimation. Partial least square (PLS) analysis was used for quantitative analysis. FTIR spectroscopy with chemometrics, using the PLS-1 st derivative spectra, could predict the content of active compounds accurate to an r2 greater than 0.99 and a standard error of prediction (SEP) less than 0.7. The developed method was successfully applied to predict the concentration of active compounds: carvacrol, thymol and p-cymene in oregano and thyme essential oils with results compared to those of the GC-MS method. The described non-destructive method can be applied in the industry instead of extraction, distillation and blend processes of the mentioned essential oils and can be extended to detect the content of carvacrol, thymol and p-cymene in active packaging and other commercial products.

“…This technique allows for slow diffusion of the antimicrobial agent from the packaging material, thus allowing a continuous antimicrobial effect on the food product surface over time (Han et al, 2014). This approach has been shown to be more effective than spraying, dipping or submerging products with or in solutions of antimicrobial agents (Lu et al, 2010, Muriel-Galet et al, 2012, Quintavalla & Vincini, 2002, Suppakul et al, 2008& Yingyuad et al, 2006. Numerous publications have reported the effects of activating biopolymerbased materials with antimicrobial substances for packaging applications (Gómez-Estaca et al, 2010, Oussalad et al, 2004, Millette et al, 2007, Gill et al, 2002, & Morsy et al, 2014 to name a few.…”

'Surface attachment of active antimicrobial coatings onto conventional plastic-based laminates and performance assessment of these materials on the storage life of vacuum packaged beef sub-primals ', Food Microbiology, 62, Abstract Two antimicrobial coatings, namely Sodium octanoate and Auranta FV (a commercial antimicrobial composed of bioflavonoids, citric, malic, lactic, and caprylic acids) were used. These two antimicrobials were surface coated onto the inner polyethylene layer of cold plasma treated polyamide films using beef gelatin as a carrier and coating polymer. This packaging material was then used to vacuum pack beef sub-primal cuts and stored at 4°C. A control was prepared using the non-coated commercial laminate and the same vacuum packaged sub-primal beef cuts. During storage, microbial and quality assessments were carried out. Sodium octanoate treated packages significantly (p<0.05) reduced microbial counts for all bacteria tested with an increase of 7 and 14 days, respectively compared to control samples. No significant effect on pH was observed with any treatment. The results suggested that these food grade antimicrobials have the potential to be used in antimicrobial active packaging applications for beef products.
