In the form of emulsion, USF will be convenien</em><em>t </em><em>and easy to use as food supplement</em><em>s</em><em> or fortificant</em><em>s</em><em>. Microemulsion is a type of emulsion that ha</em><em>s </em><em>stable droplet size</em><em>s</em><em> less than 10 </em><em>m</em><em>m. </em><em>Hence, the best</em><em> emulsifier for USF microemulsion is important to </em><em>be </em><em>determine</em><em>d</em><em>. </em><em>The </em><em>USF micro</em><em>-</em><em>emulsion was prepared by homogenizing </em><em>the sample mixtures </em><em>at 12</em><em>.</em><em>000 rpm for 20 min at USF concentration of 10% (w/v) with lecithin and tween 80 as emulsifiers at concentration of 0.5</em><em>,</em><em>1.0</em><em>, </em><em>and 1.5% (w/v). </em><em>The m</em><em>icroemulsions were analyzed for their viscosity, stability, and particle size distribution</em><em>s</em><em>, as well as microstructure</em><em>s</em><em>. The results showed that characteristics of microemulsion were affected by emulsifier type</em><em>s</em><em> and concentration</em><em>s</em><em>. Tween 80 produced better microemulsion than lecithin indicated by more stable emulsion</em><em>s</em><em>, smaller droplet size</em><em>s</em><em>, and narrower </em><em>ranges of </em><em>droplet size distribution</em><em>s</em><em>. </em><em>The i</em><em>ncreasing lectihin concentration</em><em>s</em><em> resulted in </em><em>a </em><em>narrower droplet size distribution</em><em> </em><em>but the </em><em>average droplet size was not always smaller. Conversely,</em><em> the</em><em> increasing tween 80 concentration</em><em>s</em><em> increased average droplet size</em><em>s and ranges of particle size distributions</em><em>. The most suitable emulsifier for USF microemulsion was tween 80 at concen</em><em>-</em><em>tration of 0.5%. This microemulsion contained bioactive compounds derived from USF</em><em>, namely </em><em>vitamin E (mainly tocotrienols), phytosterols, and squalene.</em></p&gt;}, number={2}, journal={Jurnal Teknologi dan Industri Pangan}, author={Estiasih, Teti and AhmadiKgs. and RizqiyahLayly Alifatur}, year={2015}, month={Dec.}, pages={189-200} }
