Soybean meal

Soybean meal is the by-product of the extraction of soybean oil. Several processes exist, resulting in different products. Soybean meal is usually classified for marketing by its crude protein content. High-protein types are obtained from dehulled seeds and contain 47-49% protein and 3% crude fibre (as fed basis).
Soybean meal is used in food and animal feeds, principally as a protein supplement, but also as a source of metabolizable energy. Typically 1 bushel (i.e. 60 lbs. or 27.2 kg) of soybeans yields 48 lbs. (21.8 kg) of soybean meal. Soybean meal is produced as a co-product of soybean oil extraction.
Soybean meal offers more metabolizable energy than any other plant protein, especially when processed in a mechanical press like the Anderson Expeller. The press leaves about 5% residual oil in the meal, which boosts fat-based energy in feed.
Soybean Flakes and High Protein or Solvent Extracted Soybean Meal are produced by cracking, heating and flaking dehulled soybeans and reducing the oil content of the conditioned flakes by the use of hexane or homologous hydrocarbon solvents. The extracted flakes are cooked and marketed as such or ground into meal.
