This invention relates to a processed soybean having a reduced urease content, the soybean being produced by decompressing and steaming. 1. A method for producing a processed soybean comprising steps (A) and (B):(A) decompressing a soybean; and(B) steaming the soybean obtained in step (A).2. The method according to claim 1 , wherein the decompressing is conducted by exposing the soybean to a reduced pressure of 30 kPa or less.3. The method according to claim 1 , wherein the steaming is performed at 80 to 150° C. over a period of 1 to 60 minutes.4. The method according to claim 1 , wherein a processed soybean that has undergone steaming is further subjected to drying and/or pulverization.5. A processed soybean obtainable by the method according to .6. The processed soybean according to claim 5 , which has urease activity of pseudopositive (+1) or less measured based on Chinese national standard GB/T5413.31-1997. The present invention relates to a processed soybean having a reduced urease content, and a method of producing thereof.Soybeans are called the meat of the field. They are rich in protein having an amino acid composition similar to that of animal protein, and contain good quality protein comparable to that of meat and eggs. Soybeans are also rich in oil (fat), and 50% or more thereof is linoleic acid, which functions to decrease blood cholesterol.
