  • How is oil extracted from soybeans?
  • Due to the moderate oil content (18 ¨C 23%mass) , it is mandatorily recovered from soybeans by solvent extraction . Currently, industries adopt a continuous-countercurrent-multistage extractor for oil extraction from vegetable oilseeds.
  • 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.
  • How is soybean oil extracted in a continuous and countercurrent process?
  • Extraction of soybean oil in a continuous and countercurrent process. Multistage extraction was experimentally reproduced from batch single-stage assays. The process efficiency was mainly limited by the oil solubility in the solvent. The minimum solvent mass flow and the number of ideal stages were calculated.
  • What is the water extraction profile of soybean collets?
  • The water extraction profile is very similar to the oil one. Moisture existing in the fresh soybean collets (6.22 ± 0.06%) was progressively transferred to E, reaching about 3.5% water in the final extract phase (E1). Fig. 5 d shows the residual oil content in R throughout the stages.
  • 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.
  • 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).
