• 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 soybean meal produced?
  • Soybean meal is produced by different processing methods such as solvent extraction (soybean flakes 1.5% oil), and mechanical extraction by screw press (soymeal press cake >5% oil). Soymeal accounts for 62.5% of total oil meal and it also represents the 61% protein source to feed livestock (A. et al., 2011).
  • What are the four steps of soybean extraction?
  • The conventional soybean extraction process consists of four steps; preparation, extraction, solvent recovery from miscella and desolventizing/toasting of meal. Modern soybean processing involves large plants with many operations that must be considered. Transportation, material handling, drying, and milling are similar to other grain processing.
  • Where did soybean oil come from?
  • Production of soybeans expanded from the southern part of the United States. The industries that process soybeans to produce soy oil and soybean meal are called processing or crushing industries. Oil from the soybeans can be removed by any one of the two oil extraction methods.
  • 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.
  • What is the preparatory section in the soybean oil manufacturing process?
  • First comes the preparatory section in the soybean oil manufacturing process. It marks the initial stage where raw soybeans are processed to make them ready for oil extraction. Upon arrival at an oil mill, seeds often contain various foreign materials acquired during harvesting or transportation.
