Abstract
ABSTRACTLipid nanoparticles are carriers to improve stability, solubility, and efficacy of bioactive compounds. In this paper, novel vitamin D3 loaded lipid nanocapsules (LNC) were produced by phase inversion method. The produced nanocapsules were characterised by particle size, polydispersity index, zeta potential, encapsulation efficiency, and encapsulation load. LNC showed sizes in the range of 31.43 to 36.66 nm. Optimum LNC formulation was selected for further analysis (such as morphological study, analysis of chemical structure, release study, and sensory evaluation). Transmission electron microscopy revealed that particles had approximately spherical shape. The Fourier transform infrared spectra indicated that no adverse reactions occurred between vitamin D3 and lipid nanocapsules. About 9.6% of vitamin released in gastric simulated solution (pH: 1.2), which indicated that LNC can protect vitamin against acidic conditions. Sensory evaluation revealed the potential application of produced vitamin D3 loaded LNC for development of fortified milk.
