“…Thus, although diffusion studies were not carried out in this work, it is likely that nisin diffuses faster from the film to the agar medium assay; subsequently, its concentration on the film-medium interface probably is not enough to show significant inhibition of L. monocytogenes for extended time. Besides, the nisin concentration was considerably lower than that reported in other studies Guiga et al, 2010;Kristo, Koutsoumanis, & Biliaderis, 2008;Li, Kennedy, Peng, Yie, & Xie, 2006) where growth inhibition of L. monocytogenes or L. innocua was observed. On the contrary, AM could have been released more slowly from the caseinate films, thus maintaining an effective concentration on the interface film-agar surface where L. monocytogenes were grown.…”

“…Most of the findings have reported greater retention and enhancement of the antimicrobial activity of nisin against Listeria spp. when it is added to the films or coatings compared to its direct application on the surface of foods (Guiga et al, 2010;Sanjurjo et al, 2006). However, some studies concerning the desorption phenomenon of the t (h) Figure 3.…”

“…Propiedades físicas de películas de caseinato con agentes antimicrobianos de S. infantarius aislado del Pozol (AM) y nisina (Nis). antimicrobial agent from biopolymer film showed that a quick desorption of the those agents induces a rapid loss of its activity (Guiga et al, 2010). Nonetheless, other factors might also affect the effectiveness of the antimicrobial film, such as the intermolecular forces between polymer matrix and antimicrobial agent, and the connectivity of the macromolecular network.…”

“…Recently, bacteriocins have been incorporated into packaging films based on biopolymers, as an attractive option to develop antimicrobial and biodegradable food packaging Guiga et al, 2010;Imran, El-Fahmy, Revol-Junelles, & Desobry, 2010;Imran et al, 2012;Xu, Li, Kennedy, Xie, & Huang, 2007). The implementation of that kind of emerging technology has some advantages, which include its food-grade safety owing to the many bacteriocins being produced by food-grade lactic acid bacteria, the usual heat stability of the bacteriocins and the relatively high efficacies of the different bacteriocins against various primary pathogenic and spoilage microorganisms that can cause problems in minimally processed foodstuffs.…”

Antimicrobial films were formulated with sodium caseinate (C), glycerol and antimicrobial substances (AM) produced by Streptococcus infantarius. The antilisterial activity of the films was evaluated using Listeria monocytogenes as test microorganism and two incubation conditions: T = 35°C, 32 ± 10% RH and T = 4°C, 98 ± 10% RH. A comparison of the antimicrobial action was made with caseinate films carrying equivalent activity units of commercial nisin (Nis). At 35°C and 32% RH, AM increased the lag-phase and inhibited 80% of the growth of L. monocytogenes. At 4°C and 98% RH, C-Nis and C-AM films extended the lag-phase of the bacterial growth up to 11 and 38 days, respectively. AM showed a higher antilisterial effect than nisin at both incubation conditions. The incorporation of AM or Nis did not produce significant differences in the barrier properties of the films, but AM acted as an additional plasticizer into the films.Keywords: bacteriocins; water vapour permeability; oxygen permeability; nisin; pozol; caseinate Se formularon películas con caseinato de sodio (C), glicerol y sustancias antimicrobianas (AM) producidas por Streptococcus infantarius. La actividad antilisterial de las películas fue evaluada usando Listeria monocytogenes como microorganismo indicador y dos condiciones de incubación: T = 35°C, 32 ± 10% HR y T = 4°C, 98 ± 10% HR. Se comparó la actividad antimicrobiana con películas de caseinato que contenían nisina comercial (Nis) en unidades de actividad equivalentes. A 35°C y 32% HR, AM incrementó la fase lag e inhibió el 80% del crecimiento de L. monocytogenes. A 4°C y 98% HR, C-Nis y C-AM extendieron la fase lag del crecimiento bacteriano hasta 11 y 38 días, respectivamente. AM mostró mayor actividad antilisterial que nisina en ambas condiciones de incubación. La incorporación de AM o Nis no generó diferencias significativas en las propiedades de barrera de las películas, pero AM actuó como plastificante adicional en las películas.Palabras clave: bacteriocinas; permeabilidad al vapor de agua; permeabilidad al oxígeno; nisina; pozol; caseinato

“…Marudova et al (2005) studied the deposition of alternating layers of pectin and chitosan on a solid surface, observing the effect of pH on the adhesiveness and thickness and also the influence of the multilayered structure on film functionality. The effect of different film architectures (Guiga et al 2010) on nisin activity has also been reported. The combination of polysaccharides and/or proteins with lipids in blends, emulsions, or multilayer structures have been also studied for controlling edible film properties (Phan The et al 2002;Cho et al 2002).…”

Over the last years, considerable research has been conducted to develop and apply edible films and coatings made from a variety of agricultural commodities and/or wastes of food product industrialization. Such biopolymers include polysaccharides, proteins, and their blends. These materials present the possibility of being carriers of different additives, such as antimicrobial, antioxidant, nutraceuticals, and flavorings agents. In particular, the use of edibles films and coatings containing antimicrobials has demonstrated to be a useful tool as a stress factor to protect foodstuff against spoilage flora and to decrease the risk of pathogen growth. The more commonly antimicrobials used are organic acids, chitosan, nisin, the lactoperoxidase system, and some plant extracts and their essential oils. For the selection of an antimicrobial, it must be considered the effectiveness against the target microorganism and also the possible interactions among the antimicrobial, the film-forming biopolymer, and other food components present. These interactions can modify the antimicrobial activity and the characteristics of the film being these key factors for the development of antimicrobial films and coatings. The main objective of this article is to review the bibliography of the last years concerning the main hydrocolloids and antimicrobials used for developing edible films and coatings, the methods used to evaluate the antimicrobial activity, the applications and the legislation concerning edible films and coatings. Also, the different strategies related to the modification of structural characteristics and the future trends in the development are discussed. The information update will help to improve the design, development, and application of edible films and coatings tending to increase the safety and quality of food products and to prepare for food legislation changes that might be necessary while identifying future trends concerning a better functionality of edible films thought as a stress factor for lengthening shelf life of food products.
