Soymilk is an aqueous extraction of the soybean resembling milk. The nutritional composition, appearance, and flavor of good quality soymilk is remarkably similar to that of cow's milk. All traditional soymilks were filtered, whereby the okara (insoluble soybean pulp) was removed. Some modern soymilks are suspended, containing all of the original soybean except its hull, while others are made from soy protein isolates.
