摘要: In an apparatus for continuously manufacturing microspheres, a dispersed phase (O) is supplied to a chamber 27 for the dispersed phase inside of a bulkhead member 26 via a supply port 23. Thereafter, the dispersed phase enters into a gap 31 between a plate 22 via a supply port 29 in a base 25. The dispersed phase which enters into the gap 31 grows microspheres (particles) having a certain diameter while passing through a microchannel 33 by pressure applied by, for example, a pump, and is mixed with a continuous phase (W), so that microspheres are produced. The thus-produced microspheres float or are suspended in the continuous phase without needing any particular external force in response to their specific gravity, allowing the microspheres to be generated and withdrawn from a withdrawal port 32 at a significantly reduced pressure in comparison to conventional methods and apparatus.

摘要: A microchannel apparatus includes a plural partition walls 4 formed as extensions of plural microchannels 1 toward a continuous phase, and a flow path 5 is formed between adjacent ones of the partition walls 4. A dispersed phase pumped into a continuous phase via each microchannel 1 generates nearly perfect spheres in the course of passing through the microchannel and the flow path 5 in between the partition walls 4, thereby producing emulsions comprising fine and homogenous microspheres.

摘要: According to the present invention, it is possible to produce emulsions containing a material that are insoluble or that have low solubility with respect to water and oil in a high concentration, so as to obtain emulsions which can be preserved for a long period of time. More specifically, ethanol, to which polyglycerol oleic acid ester (PG) is added, and vegetable oil, are stirred with a homogenizer or an emulsification method such as a membrane emulsification or a microchannel emulsification, thereby obtaining E/O type emulsions or E/O/W type emulsions wherein ethanol drops in which polyphenol is dissolved in a high concentration are dispersed into vegetable oil.

摘要: A method is disclosed for activating a lipase by adding a solution of lipase in an aqueous buffer at a pH near neutrality to an organic phase, e.g., tetradecane. Under these conditions lipase is activated as a function of an organic-and-water boundary surface between the organic and water phases. The lipase that is activated in this manner remains active even after lyophilization to remove the water and the organic phase. This activated lipase efficiently catalyzes a fat reforming reaction in non-aqueous and nano-aqueous conditions.
