Tocotrienols are palm phytonutrients which have been recently reported to possess enormous health and medical benefits. They have huge market potential in the pharmaceutical, nutraceutical, food and cosmetic sectors, however they are expensive, vulnerable in nature and difficult to handle due to their liquid state. Tocotrienols can be stabilized and converted to a solid form by encapsulating them in a core-shell structure using a polymer matrix as shell material. The current industrial practice uses gelatin, an animal derived material, to form capsule shell via a thermal-gelation process. In this project, a biopolymer derived from plant, alginate, will be used and the capsule shell will be formed using an ionostropic-reticulation process. However, this process is normally performed in a batch mode with low productivity and inconsistent product quality. The main objective of this project is to develop a continuous microencapsulation process by integrating various processing steps: the compound drop formation process, the shell reticulation process, the curing process and the capsule separation process into a single step process. The effects of process parameters of each processing step on the physicochemical properties of the reticulated shell and the encapsulated oil will be studied independently. The understanding generated from these studies will facilitate the design and development of an integrated process equipment and process control to improve process productivity, reduce water consumption and ensure consistent capsule quality.
