Wet Corn Milling and Starch Manufacturing

This U.S. industry comprises establishments primarily engaged in wet milling corn and other vegetables (except to make ethyl alcohol). Examples of products made in these establishments are corn sweeteners, such as glucose, dextrose, and fructose; corn oil; and starches (except laundry). It has no schema of its own: companies here are mapped on the Manufacturing schema, and what it does not cover is recorded as gaps.
