The Effect of Pharmaceutical Excipients for Applying to Spray-Dried Omega-3 Powder

Omega-3 fatty acid plays a role in protecting cells in the human body, maintaining the structure of the cell, and helping smooth metabolism. Also, it inhibits the formation of blood clotting and is effective in enhancing the formation of bone. However, the instability due to fatty acid oxidation and a fishy smell are the reasons it is avoided by people. In this study, we tried to obtain the omega-3 powder through spray-drying method using a variety of binders and surfactants for improving the limit of omega-3 fatty acid. First of all, an olive oil was used instead of omega-3 for optimization of the preparation of spray-dried omega-3 powder. Through the screening of binders and surfactants, γ-cyclodextrin and hydrogenated lecithin were chosen as a binder and a surfactant, respectively. Omega-3-loaded spray-dried powder was obtained, eventually. The morphology of omega-3-loaded spray-dried powder was spherical of 310 nm and the DHA amount was 98%. This study suggested that the transformation of omega-3 fatty acid into solid state by spray-drying using a binder and a surfactant was successively performed.
