Adsorption of nisin on raw montmorillonite

Effect of different compatibilizers on environmentally friendly composites from poly(lactic acid) and diatomaceous earth

“…Sodium montmorillonite has been incorporated in a thermoplastic starch/PLA blend, obtaining a mechanically improved composite since nanoclay acts as compatibilizer between the two matrices . Summarizing, several research studies have documented that silicates and nanoclays offer high relevance to this technology due to their abundance, low cost, natural origin and good processability, and, which is more important for the packaging industry, according to the US Food and Drug Administration and the European Food Safety Authority they are suitable to be used in food packaging …”

“…11 Summarizing, several research studies have documented that silicates and nanoclays offer high relevance to this technology due to their abundance, low cost, natural origin and good processability, and, which is more important for the packaging industry, according to the US Food and Drug Administration and the European Food Safety Authority they are suitable to be used in food packaging. 12,13 Another interesting characteristic of the clays is the possibility of using them as carriers for the controlled release of active agents during food packaging, extending the shelf-life. Some research groups have analysed the proper use of nanoclays in active packaging for various purposes.…”

Adsorption of plantaricin Q7 on montmorillonite and application in feedback regulation of plantaricin Q7 synthesis by Lactobacillus plantarum Q7

“…It indicated that a modification of the interlayer space distance occurred due to an intercalation of plantaricin Q7 in montmorillonite layers, suggesting that plantaricin Q7 probably adsorbed on montmorillonite by 'frustrated intercalation' . Previous studies have suggested that nisin and pediocin were adsorbed into clays by electrostatic interactions [8,9]. TEM micrographs of montmorillonite and plantaricin Q7 adsorbed montmorillonite are shown in Fig.…”

“…Thus, bacteriocins need a carrier to increase their stability and efficacy in food applications. Clay may allow a controlled release of antimicrobial peptides and are regarded as safe food carriers and additives by US Food and Drug Administration and European Food Safety Authority [8]. Clay may allow a controlled release of antimicrobial peptides and are regarded as safe food carriers and additives by US Food and Drug Administration and European Food Safety Authority [8].…”

“…According to previous reports, clays could be used as carriers of active molecules or drugs to improve their stability [7]. Clay may allow a controlled release of antimicrobial peptides and are regarded as safe food carriers and additives by US Food and Drug Administration and European Food Safety Authority [8]. Nonetheless, only nisin and pediocin were researched for adsorption into clays [9,10].…”
