The purpose of the present invention is to provide a technology of reducing soybean smell and parageusia of soybean milk and bean curd obtained by coagulating the soybean milk without deteriorating the yield. In a process of producing soybean milk by dissolving soybean flour obtained by grinding soybean into water, a method for producing soybean milk according to the present invention comprises: performing the grinding process without performing a thermal inactivation treatment process of enzymes in advance； dissolving the soybean flour in water while deaerating the soybean flour obtained by the grinding process； and heating the dissolved solution to perform a thermal inactivation treatment process of the enzymes.(과제)본 발명은, 수율을 악화시키지 않고 두유 및 상기 두유를 응고시켜서 얻어지는 두부의 「대두 냄새」 및 「불쾌미」를 감소시키는 기술을 제공하는 것이다.(해결수단)대두를 분쇄하여 얻은 대두분을 수중에 용해시켜서 두유를 제조하는 과정에 있어서, 사전에 효소의 열실활 처리를 하지 않고 상기의 분쇄를 하고, 상기 분쇄에 의하여 얻어진 대두분을 탈기하면서 수중에 용해시킨 후에, 상기 용해액을 가열하여 효소의 열실활 처리를 한다.
