Kix is a cereal brand that was introduced in 1937 by the General Mills cereal brand in Golden Valley, Minnesota. The cereals are extruded expanded puffed grain products made with whole grain corn. The grain is processed and expanded (water is addedand the corn is pulverized). Cooking of Kix occurs in the extruded and then the dough is formed into the desired shape by extrusion through a die. It was the first cereal manufactured with this process.
