Fuente: WIPO "dairy products" PURPOSE: A production method of natural soymilk is provided to reduce the unique smell of beans, and to offer clean and savory taste. CONSTITUTION: Peeled and half-cut beans are soaked in hot water at the predetermined temperature for a predetermined time. The softened half-cut beans are ground in an anaerobic condition using a grinder. Steam at the predetermined temperature is supplied to the obtained bean slurry for a predetermined time for the enzyme deactivation of lipoxygenase a trypsin inhibitor. The heat-processed slurry is inserted into a solid-liquid separator to obtain bean curd dregs and soymilk liquid. The soymilk liquid is inserted into a vacuum deodorizer for removing the smell of beans from the soymilk liquid. The deodorized soymilk liquid is homogenized in a homogenizer, and cooled.
