  • What are the current practices in soybean processing and utilization?
  • This chapter describes current practices in soybean processing and utilization. More significant changes have occurred in soybean processing and utilization in the last 20 yr than during the crop’s prior history in the USA. Considerable variation can occur in quality levels of soybean, meal, and oil.
  • Is soybean oil a by-product of soybean meal production?
  • Soybean oil is a by-product of soybean meal production, and it is substituting other vegetable oils, where palm oil can be identified as the most important marginal source. Furthermore, a by-product from ISP production is carbohydrates, which substitute alternative animal feed, mainly barley.
  • What are the three stages of soybean oil processing?
  • Three stages of soybean oil processing are studied in detail: preprocessing, extraction and separation, and postprocessing. For extraction, hexane (current industrial process) and supercritical CO2 (research and development [R & D ] laboratory-scale process) methods are compared in detail.
  • When was soybean introduced to North America?
  • Introduction of soybean to North America occurred at the beginning of the 20th century for use as an alternative oil source. It was soon realized that the residual meal product from oil processing was a quality protein source as well; this was first proven in animal feeds and later in human foods.
