| Outline of Final Research Achievements |
Oil biomass contains triglyceride, its hydrolysate (free fatty acid, FFA) and lipid-soluble bioactive compounds such as vitamin E (tocopherol and tocotrienol) and phytosterol. However, no industrial technology to efficiently recover bioactive compounds with lower thermal stability has been established. We have proposed a novel reaction and separation technology at 50 ℃ and atmospheric pressure using ion-exchange resins as catalysts and adsorbents. The technology enables the complete conversions of both triglyceride and FFA to biodiesel and selective recovery of vitamin E from oils. Especially, tocotrienol has succeeded to be recovered at the highest ratio, more than 60 %. The solubility of phytosterol in biodiesel becomes lower than that in oils, so that phytosterol has been crystallized at room temperature and easily recovered. Therefore, this novel technology to simultaneously produce vitamin E, phyrosterol and biodiesel from biomass gives profitability to the enterprise.
