To protect vitamin D3 during cold storage and exposure to UV-light, vitamin D3 has been entrapped in
microspheres formed by bovine protein b-lactoglobulin (blg) and lysozyme (Lyso) from egg white. The
behaviour of the blg/Lyso microspheres in simulated intestinal fluid and their impact on the kinetic
release of D3 were determined. The impact of the D3-loaded blg/Lyso microspheres on the bioavailability
of D3 was evaluated in vivo by force-feeding rats
