Biopreservatives against foodborne bacteria: combined effect of nisin and nanoncapsulated curcumin and co-encapsulation of nisin and curcumin.

Unlabelled: Nisin, a bacteriocin widely used in the food industry, and curcumin, the yellow pigment extracted from turmeric ( L.) stand out among the numerous natural preservatives that have antimicrobial activity. The conversion of these compounds into nanoparticles could be interesting as an alternative to improve technological aspects (such as the low water solubility of curcumin) and to evaluate how synergism could take place in the case of co-encapsulation.
