Abstract
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.
