Transport and release in nano-carriers for food applications

Abstract

Encapsulation of active compounds such as nutraceuticals or preservatives increases their concentration, bioavailability and stability in food products. Nanoparticle carriers are an effective encapsulation method that provides protection from environmental degradation agents and control over the rate of compound release. This review focuses on the parameters affecting transport in a number of nanoparticle types used in (or with the potential for) food and beverage applications: Emulsions and Pickering emulsions, solid lipid nanoparticles (SLN), nanostructured lipid carriers (NLC), liposomes, and colloidosomes. Emphasis is placed on the effect of medium conditions, nanoparticle structure and size, and the role of the shell.
