Soybean meal, or soymeal, is the material remaining after solvent extraction of oil from soybean flakes, with a 50% soy protein content. The meal is 'toasted' (a misnomer because the heat treatment is with moist steam) and ground in a hammer mill. Ninety-seven percent of soybean meal production globally is used as livestock feed.

Modern soybean processing involves removal of the oil by solvent extraction; the oil is then further processed. The residual protein meal is of high quality and is used in food and animal feed (see Chapters 7 and 8).Soybean hulls may be either removed or left in the meal.
