The present invention provides a process for producing DHA (docosahexaenoic acid)-containing tofu or soybean milk drink, or a dry powder thereof which does not influence taste even if a DHA-containing fish oil is incorporated at a high concentration, which is stable and of which starting materials are inexpensive. A DHA-containing fish oil emulsion is prepared by mixing soybean milk with a DHA-containing fish oil at a weight ratio of 1:0.2 to 1, and stirring the mixture. Then, soybean milk drink can be produced by further diluting this emulsion with soybean milk to give a predetermined DHA concentration. Still further, DHA-containing tofu can be produced by coagulating the soybean milk containing this emulsion with the addition of a coagulant. Since the same soybean milk as the starting material of tofu or soybean milk drink is used as an emulsifying agent, such a product is obtained that even if DHA is contained at a high concentration, this does not influence a taste or properties of the product. A dry powder can be obtained by freeze-drying, vacuum-drying or spray-drying this tofu or soybean milk drink as required.
