Monitoring nisin desorption from a multi-layer polyethylene-based film coated with nisin loaded HPMC film and diffusion in agarose gel by an immunoassay (ELISA) method and a numerical modeling

Innovative multilayer antimicrobial films made with Nisaplin® or nisin and cellulosic ethers: Physico-chemical characterization, bioactivity and nisin desorption kinetics

“…Five measurements were performed at random positions by putting films on a black reference surface to determine L⁎, a⁎ and b⁎. Film opacities (FO) were calculated as follows (Chollet, Swesi, Degraeve & Sebti, 2009):…”

“…These parameters play a major role on nisin solubility, bioactivity, stability, desorption rate from films and diffusion into food matrices. Some previous studies investigated nisin diffusion into food matrices (Ripoche, Chollet, Peyrol & Sebti, 2006;Sebti, Blanc, Carnet-Ripoche, Saurel & Coma, 2004) and some concerned the desorption phenomenon of the antimicrobial agent from biopolymer films (Buonocore, Del Nobile, Panizza, Corbo & Nicolais, 2003;Chollet, Swesi, Degraeve & Sebti, 2009;Guiga et al, 2009). These published results show a quick desorption of the antimicrobial agent inducing a rapid loss of its activity.…”

Effect of BOPET film surface treatments on adhesion performance of biodegradable coatings for packaging applications

“…http Nitrocellulose and PVdC (Polyvinylidene chloride) copolymer are the most common surface coatings used, even if several synthetic resins, acrylics, biological and natural compounds based on cellulose, polysaccharides or proteins, are used for varnishing the web and to improving barrier formation and heat sealing [1,2,[4][5][6][7][8]. Several innovative coatings are proposed in the literature in order to functionalize polymeric substrates and to promote natural and eco-compatible solutions [9][10][11][12]. The adhesive properties of amorphous polymers could be an interesting choice for replacing typically used polyolefins as sealant layers [13].…”

The effects of nisin on Staphylococcus aureus count and the physicochemical properties of Traditional Minas Serro cheese

“…It has been suggested as a natural antimicrobial to be used as a biopreservative in foods, including dairy products, and is generally regarded as safe (GRAS) (Adams, 2003). In addition, nisin is the only bacteriocin authorised for use in the food industry (Chollet, Swesi, Degraeve, & Sebti, 2009). Many recent studies have shown the effect of nisin against S. aureus and other Gram-positive bacteria (Cabo, Herrera, Crespo, & Pastoriza, 2009;Kim, Choi, Bajpai, & Kang, 2008;Malheiros, Daroit, Silveira, & Brandelli, 2010;Mitra, Chakrabartty, & Biswas, 2010;Pathanibul, Taylor, Davidson, & Harte, 2009).…”
