  • 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 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 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.
  • 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).
  • 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 to produce high-quality pressed soybean oil?
  • We can also provide pressing process for soybean to produce high-quality pressed soybean oil. Different dehulling processes such as hot dehulling, warm dehulling, and cold dehulling are available according to clients¡¯ dividual requirements for meal protein content.
