  • What is modern soybean oil?
  • Modern soy oil is a stable high quality triglyceride ingredient used widely in commercial processed foods. It is without other lipid contaminants and available at a reasonable cost. Modern soybean processing starts with solvent extraction to obtain crude oil and defatted meal.
  • What are the sources of wastewater from soy oil processing?
  • 1. Wastewater Control The sources of wastewater from soy oil processing are (I) process wastewater, which has been in contact with oil, (2) noncontact cooling water that is uncontami nated because it has been circulated in pipes, and (3) rainwater runoff, which may have been in contact with contaminated areas (Smallwood 1995).
  • How is oil extracted from soy flakes?
  • During solvent extraction oil is removed from the soy flakes by an organic solvent to form an oil/solvent mixture called a miscella. The oil is recovered from the miscella by removing the solvent by steam stripping. Most commercial oil extraction is currently by hexane extraction, but other solvents have been considered.
  • How is soybean processed?
  • Modern soybean processing starts with solvent extraction to obtain crude oil and defatted meal. Most defatted meal is used for animal feed and only a small portion is further processed into different types of soy protein products for human consumption (see Chapter 8). Crude oil contains variable amounts of nontriglyceride materials.
  • How is soybean oil extracted?
  • Extrusion has been used as pretreatment prior to expeller pressing of soybean oil, extracting over 70% of oil compared to single-step expelling, which yielded 60%.
  • Is a soybean extruder a good investment?
  • Some success has also been found by extruding soybeans at 10-14% moisture (Rittner 1984; Nelson et al. 1987). To summarize, the additional expense of an extruder can only be justified if there is a subsequent increase in extraction efficiency and oil quality (Kemper 1995).
