Nixtamalization (IPA: [ˌnɪkstəmɑlɪˈzeɪʃn]) typically refers to a process for the preparation of maize (corn), or other grain, in which the grain is soaked and cooked in an alkaline solution, usually limewater, and hulled. The term can also refer to the removal via an alkali process of the pericarp from other grains such as sorghum.
