  • How is soybean oil extracted?
  • In the USA, virtually all soybeans (99%) are solvent-extracted. This method is the most efficient and about 1.5% oil is left in the resulting soybean meal. The second method consists in a mechanical extraction by a screw press (expeller). This method yields less oil and a soybean meal containing more than 5% residual oil.
  • How is oil extracted from soybean flakes?
  • The most common process consists in extracting oil from soybean flakes by solvent. In the USA, virtually all soybeans (99%) are solvent-extracted. This method is the most efficient and about 1.5% oil is left in the resulting soybean meal. The second method consists in a mechanical extraction by a screw press (expeller).
  • Why do soybeans need to be heated before oil extraction?
  • Heating soybeans prior to oil extraction or heating soybean meal is very important as heat can destroy heat labile antinutritional factors present in soybean seeds. Heat has also some effects on protein solubility of soybean meal, which is important for its nutritive value.
  • What are the different types of soybean products?
  • The major soybean products for feed use are soybean oil, soybean meal (the by-product of oil extraction) and whole soybeans (usually called "full-fat"), the latter being usually heat processed in order to destroy the antinutritional factors and improve their feed value. These products can be ground, pelleted, flaked or powdered.
