The enhancement of stability of light sensitive CoQ10 was achieved by preparation of coenzyme Q10-loaded Nanostructured Lipid Carriers through High Pressure Homogenization (HPH). Well-dissolved lipids of CoQ10 were selected, optimized ratio of emusifiers and lipids were determined for the formulation. Obtained by photon correlation spectroscopy (PCS), the mean particle size of CoQ10-NLC was 112 ± 7 nm within 60 days after preparation. In terms of centrifugal stability, results of laser diffraction (LD) analysis eliminated the existence of aggregated particles with micrometers and showed almost no size growth before and after centrifugation. Zeta potential values were from -50 to -55 mV with pH in the range of 6.56–6.72. The concentration of CoQ10-NLC measured by UV-Vis spectroscopy was as high as 8.13 mg/mL.

Vitamin A Palmitate-loaded Nanostructured Lipid Carriers were prepared by High Pressure Homogenization (HPH) technique. The influences of storage conditions such as time and temperature on the physical and chemical storage stability of VAP-NLCs were studied in details. Preparation and physicochemical properties of VAP lipid nanoparticles were investigated using various analytical equipments such as TEM, photon correlation spectroscopy (PCS), laser diffractometry (LD) and ultraviolet spectrophotometer. The respective optimal HPH pressure and cycles were 70MPa and 5 cycles, so VAP-NLC dispersions under the optimized condition gave rise to the entrapment efficiency (EE) of 99.8%, PI of 0.234, mean diameter of 144±1.7 nm (2% VAP loading capacity). In addition, VAP lipid nanoparticle has a distinct spherical shape, its particle sizes were around 60–330 nm according to VAP contents and zeta potential values -18~-23 mV. Furthermore, the pH of VAP-NLC dispersion was near to 7.0. This study showed that VAP-NLC could hopefully be applied for food products.
