Production of Sago (Metroxylon Sp.) Starch Nanoparticles Using Hydrolysis-High Shear Homogenization (HSH) Method

Research on sago starch modification has been carried out to the form of starch nanoparticles. Starch nanoparticles is very potential to be used in the pharmaceutical, cosmetic, bioplastics and paper industries, as surface sizing, biodegradable coatings or adhesives. The technology of nanoparticle production has been quite developed, but there are some disadvantages, such as small yield, long processing time, expensive production equipment, and limited availability. The purpose of this study is to modify the efficient and applicable method to produce starch nanoparticles in the scale of mini plant. Method modification specified is a combination treatment of hydrolysis - high shear homogenization. This method has succeeded to obtain starch nanoparticles with 70% yield, and 36% crystallinity. The particle size obtained ranges from 118.6 nm. The optimal production process is obtained in 24 hours hydrolysis treatment and 3 hours of homogenization. The production cost of starch nanoparticles is 1.430,000 / kg.
