碩士 === 國立雲林科技大學 === 化學工程與材料工程系 === 107 === This study research that the pectin polysaccharide extracted from Ficus awkeotsang Makino seeds 0.1 M EDTA was added during the extraction of Ficus awkeotsang Makino and the capsule encapsulating hydrophobic substance was produced by a milli-fluidic device. First, the characteristics of the fabricated Ficus awkeotsang Makino the film was transformed by Fourier transform Infrared light, moisture content, water permeability and then analysis. Ficus awkeotsang Makino the seed is a rich source of polysaccharides gel, its main component is low-methyl pectin, low-methyl pectin and metal ions will form a network cross-linking, so come evaluation of the suitability as a capsule. Studies have shown that the film produced by Ficus awkeotsang Makino extracted with EDTA has a stronger structure than the film without EDTA extraction and the loss rate of the film of the calcium ion and the EDTA extraction film in the in vitro erosion test. 52% and 47%, respectively, demonstrating that the film extracted using EDTA has less solubility in the gastrointestinal tract than the unused EDTA. And adding glycerin as a plasticizer, the gel structure is increased in elasticity, and the capsule is not easily broken when dried. Under the optical micrograph. By controlling the flow, the core diameter of 1.4 mm -1.9 mm and the gel has an outer diameter of 2.1 mm -2.8 mm core-shell capsules, it can be seen that there is a successful encapsulate of soybean oil with red dye in the capsule, and there is a clear boundary, which proves that the milli-fluidic device can successfully encapsulate the capsule with the hydrophobic substance and can also be stable control the production of capsules of different diameter Keywords: Ficus awkeotsang Makino polysaccharide, hydrophobic bioactives, milli-fluidic device.
