  • 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.
  • 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.
  • 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).
  • 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).
  • When was soybean oil first used in margarine?
  • However, according to Dutton (1981) in the early 1940s, soybean oil was considered a poor quality oil, not suitable for food use, and more appropriate for use in industrial paints. It was first used in margarine in World War II due to the shortages of other fats and oils, but its use was limited to 30% of the product.
  • How to prepare soybeans before extraction?
  • Conventional preparation of soybeans before extraction consists of cleaning (scal ping), drying, cracking, dehulling (optional), conditioning, and flaking. The first preparation step is cleaning to remove foreign materials from the soy beans.
