  • 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 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 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 remove impurities from crude soy oil?
  • To remove some of these impurities from the crude soy oil and convert it to a high quality edible oil, it is necessary to subject crude oil to a series of refining operations, including degumming to remove lecithin, neutralization to separate out free fatty acids and bleaching to remove pigments and the residues of previous refining steps.
