Latest Patents

Shuji Doi holds a patent for a "Process for the manufacture of packed aseptic soybean curd." This process involves thermally treating dehulled and hypocotyl-removed soybeans with superheated steam to sterilize them. The soybeans are then ground in the presence of heated water to create a green slurry. This slurry is filtered to separate and obtain soybean milk, which is subsequently heated to sterilize and denature the soybean protein. A coagulant is aseptically added to the denatured soybean milk, which is then filled into and sealed within an aseptic container. Finally, the soybean milk is heated to induce coagulation within the container. This innovative method enhances the safety and quality of soybean curd products.
