Formation and potential uses of milk proteins as nano delivery vehicles for nutraceuticals: A review

The aim of this review was to highlight the progress achieved in the use of milk protein as nano vehicles for nutraceuticals. Reassembled casein and β‐casein micelles and core/shell nanoparticles from casein with other biopolymers have been prepared. Also, cross‐linking of casein micelles has developed stable nanoparticles. Nanogels of whey proteins (WP), β‐lactoglobulin (β‐LG) and lactoferrin (Lf) have been prepared by controlled thermal treatment, and several core/shell nanoparticles have been developed from WP or β‐LG with several polysaccharides. The developed caseins and WP nanoparticles have been used as carriers for several nutraceuticals. Examples have been presented and discussed.
