  • 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 by-products of soybean seed processing after oil extraction?
  • Major by-products generated from soybean seed processing after oil extraction were soybean meal, cakes, and expellers. These by-products have mostly been used in animal feed production (Pope et al. 2023). Among the soybean oil processing by-product, soybean meal is in high demand because of its nutritional value and ease of production (Witte 1995).
  • 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 oil extracted?
  • Processing steps like cleaning, smashing, de-hulling, conditioning, flaking, and mechanical or solvent extraction steps have been followed in soybean oil processing plants to extract oil. The solvent extraction method using hexane has been widely used for the extraction of soybean oil.
  • 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.
  • How is crude oil produced in a soybean crushing plant?
  • The crude oil is usually water degummed in the crushing plant which generates an additional flow, consisting of gums (or lecithin). Table 1 presents the main quality parameters (optimal contents) of the major products from soybean crushing.
