Other Nanoencapsulation Technologies for Food Antimicrobial Agents

Other nanotechnology strategies such as nanogels have also been studied to encapsulate antimicrobial agents. Nanogels including nanohydrogels and nanoorganogels, three-dimensional networks formed via covalent linkages or self-assembly, are promising carriers for natural antimicrobials due to their high-loading capacity, high stability, and unique release properties. Encapsulation of antimicrobial agents such as Mentha piperita essential oils within a nanogel has other benefits such as controlled and sustained release of a centain amount of oils from the carrier for a longer time (Beyki et al., 2014). Essential oils encapsulated in chitosan—cinnamic acid nanogel showed high antifungal activity under nonsealed condition. Nanolaminates, nanotubes formed from globular proteins and polysaccharides also showed the potential for the food applications with encapsulated antimicrobial agents (Weiss et al., 2006; Graveland-Bikker and De Kruif, 2006).
