<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a polyglycerin condensed-ricinoleic acid ester that slows down the coagulation speed appropriately when incorporated with a coagulant for soybean curds and allows the manufacture of soybean curds of good qualities. <P>SOLUTION: The manufacturing method of the polyglycerin condensed-ricinoleic acid ester comprises a step (I) for obtaining a condensed ricinoleic acid by subjecting ricinoleic acid to a polycondensation reaction, and a step (II) for subjecting the condensed ricinoleic acid obtained in the step (I) and polyglycerin to an esterification reaction, where the condensed ricinoleic acid obtained in the step (I) is one having a predetermined high molecular weight ratio of at least 1. <P>COPYRIGHT: (C)2008,JPO&INPIT |
