An object of the present invention is to provide a coagulant composition for tofu exhibiting high dispersibility in soy milk, even when the composition comprises a large proportion of an inorganic salt coagulant. The composition requires no use of a specially designed coagulating machine equipped with a high-speed dispersion mixer, and is thoroughly dispersed in soy milk merely by mixing with conventional low-speed stirrer. The composition coagulates soy milk to give tofu with good taste and good mouthfeel. In particular, the present invention provides a coagulant composition for tofu, the composition comprising (a) an inorganic salt coagulant, (b) a polyglycerol ester of interesterified ricinoleic acid, (c) a lecithin and/or a diacetyltartaric and fatty acid ester of glycerol and (d) an oil component.
