Soybean Refinery Process Modeling

  • What are the by-products of refining soybean oil?
  • Refining of soybean oil, to make a neutral, bland-flavored, and light-colored oil, results in several by-products. The by-products consist of various mixtures of phosphatides, unsaponifiables, glycerides, free fatty acids, and soap. Lecithin contains mostly hydratable phosphatides, together with some free fatty acids and neutral oil (glycerides).
  • Is degumming necessary for refining soybean oil?
  • Degumming is not essential for the refining process, and it is common practice for many processors to refine crude soybean oil without degumming (2). Soapstock from refining nondegummed oil is much greater in quantity than that from degummed oil and has a higher content of phosphatides, which would have been removed in degumming.
  • What percentage of soybean oil is recovered by water degumming?
  • The amount recovered by water degumming varies depending upon the oil quality but will usually be 2.5 to 3.0% of the crude soybean oil degummed. Lecithin processing and utilization are covered in detail in Chapter 10. Soapstock, or refining byproduct lipids, consists of soap, neutral oil, phosphatides, and some unsaponifiables.
  • What is crude soybean oil?
  • Crude soybean oil isobtained by seed pressing or solvent extraction processes and mainly comprises of free fatty acids, triglycerides, trace elements, heavy metals, sterols, phospholipids and other minor impurities (Lin et al., 1997, Koris and Vatai, 2002, Hafidi et al., 2005 ).
