- Abstract
Vitamin D is an essential vitamin for bone marrow development and immune function, which is mostly synthesized in the skin through sun exposure. The high global prevalence of vitamin D deficiency requires a feasible approach to administer vitamin D to a larger number of population in a shorter amount of time, and this may be achieved through food fortification. Food fortification using nanostructured lipid carriers (NLC) and nanoemulsions appears to be an ideal method to enhance bioavailability, stability, and solubility of bioactive compounds. The aim of this study was to develop NLC and nanoemulsion forms of vitamin D to evaluate its efficacy for further enrichment of dairy products. NLC containing Precirol and nanoemulsion containing vegetable oils were prepared and characterized for polydispersity index, particle size, zeta potential, particle shape, crystal properties, stability, encapsulation efficiency, and releasing. Vitamin D3 NLC size was in the range of 123.4 to 210.6 nm and for nanoemulsion 137.6 to 171.6 nm, respectively. Optimal NLC and nanoemulsion carriers were selected for morphological assessment, encapsulation efficiency, thermal analysis, and release study. Scanning and transmission electron microscopy revealed that particles had approximately spherical shape. In gastric simulated solution (pH = 1.2), NLC and nanoemulsion form of vitamin D3 released 9.3% and 26.9% of vitaminD3, respectively. This indicated that our formulation is able to protect vitamin D3 under acidic conditions. The results of this study revealed that NLC and nanoemulsion could be an optimal carrier for food fortification in order to improve bioavailability of bioactive compounds such as vitamin D.
