摘　　要：This study tried to establish optimal conditions for Sargassum horneri extracts loaded nanostructured lipid carriers(SHE-NLCs).Therefore,we observed various physicochemical analyzes,sugar and phenolic contents,and anti-oxidants while storing the SHE-NLCs for 28 days at different SHE addition amounts(0%-0.5%)and storage temperatures(25 and 65℃).All SHE-NLCs stored at 25℃ showed a small hydrodynamic diameter(20.1-25.4 nm)and high encapsulation efficiency(64.1%-89.3%)for 28 days.As the amount of SHE increased,the pH and electrical conductivity of SHE-NLCs significantly decreased and increased,respectively(p<0.05).Also,at 25℃,prevented a sharp decrease in the total phenolic content and antioxidant activity of SHE-NLCs as the storage period increased compared to 65℃.SHE 0.25%loaded NLCs can stably maintain the formulation structure for 28 days at room temperature while being an amount sufficiently containing the functionality of SHE.
