PURPOSE:To produce a raw flour of soybean free from heat denaturation, by pulverizing a raw soybean from which skin and embryo are removed into the flour having a specific grain size at a specific temperature using a air-cooled microjet grinder. CONSTITUTION:A dried raw soybean is subjected to skin removing processing to remove the skin from the soybean and after removing the skin, embryo causing foaming during the stirring process in production of TOFU (soybean curd) is eliminated. Then after removing the embryo, the raw soybean is powdered at ordinary temperature-65 deg.C by an air-cooling microjet grinder to provided the raw flour having 150-400 mesh for producing TOFU. When a soy milk is prepared in the iron pot for stirring and boiling using the above- mentioned raw flour, foam or ash removable by a filter box is not produced and long-term immersing and separation operation from OKARA are obviated. Therefore, the raw flour can be used for industrial production of TOFU. |
