  • 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 hexane is used to extract soybean oil?
  • However, efforts have been made to reduce the costs (Reverchon and Osseo 1994). Solvent extraction of soybeans is a diffusion process in which the solvent (hexane) selectively dissolves miscible oil components. During extraction, hexane solubi lizes soy oil from cotyledon lipid bodies in soy flakes rapidly, as soon as it enters the lipid body.
  • 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 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.
  • How do you extract soy flakes from a rotocel?
  • Most commercial extraction is by continuous, countercurrent methods. The Rotocel, or deep bed extractor, is a compact, continuous flow countercur rent system (Fig. 6.7). Soy flakes are added to rotating bins, each of which is a segment of the cylindrical Rotocel.
