| The goal of this study is to investigate the adsorption of fatty acids onto soy hull and rice hull. This study would allow us to evaluate the use of soy hull and rice hull as an adsorbent in vegetable oil processing to remove fatty acids. Currently, adsorption using silica or treatment with a sodium hydroxide is used to remove fatty acids from vegetable oils. Soy hull and rice hull are underutilized co-products of food industry. Research towards new application of these materials would benefit the food industry. Soy Hull was ground using the solvent ethanol, and rice hull using 70% ethanol. FTIR analysis was used to investigate the adsorption. The absorption at 1700 cm-1 were used as an indicator for identifying oleic acid adsorbed onto the adsorbents. Preliminary data indicates significant amount of adsorption of oleic acid by rice hull and soy hull. Research is in progress to compare the adsorption efficiency of these materials with that of silica. This study would enable us to understand the adsorption process of fatty acids onto rice hull and soy hull and to demonstrate the application of these materials in vegetable oil refining. |
