Title:
METHOD FOR PRODUCING GELATINOUS COMPOSITION, AND GELATINOUS COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/262625
Kind Code:
A1
Abstract:
Provided is a method for producing a gelatinous composition, the method including: a step for mixing lecithin that has been dissolved or dispersed in water and an organic compound (excluding lecithin) having a molecular weight of 500 or more that has been dissolved or dispersed in water to obtain a mixed liquid containing the lecithin and the organic compound; a step for freeze-drying or heat-drying the mixed liquid to obtain a solid mixture containing the lecithin and the organic compound; and a step for mixing the solid mixture, an oil component and a polar liquid to obtain a gelatinous composition. Also provided is a gelatinous composition produced using the production method.
