Nanostructured lipid carriers loaded with free phytosterols for food applications.

The objective of this study was to develop nanostructured lipid carriers (NLCs) with free phytosterols (FP) using conventional fats and oils. Lipid matrices (LMs) and NLCs were produced with high oleic sunflower oil, fully hydrogenated canola (CA) and crambe (CR) oils by high-pressure homogenization (HPH). The NLCs were evaluated for hydrodynamic diameter (Z-ave), polydispersity index (PDI), and zeta potential (ZP).

Solid lipid nanoparticles as carriers for lipophilic compounds for applications in foods.

Nanotechnology is a new subject of interest in the field of food industry. Therefore, scientific and technological studies have been intensified in the last 10 years because of the promising results associated with the potential application of functional properties in food products, such as physical and chemical stability, protection and controlled release of bioactive compounds, and facilitated solubility of lipophilic compounds. Lipids have been used as raw material for the preparation of nanostructures, mainly owing to the solubilization capacity of lipophilic bioactive compounds, as well as because of the advantage of potentially using natural ingredients for production on an industrial scale.
