• What are the uses of soybean oil residues in a biorefinery?
  • Residues obtained during soybean oil extraction, as well as the ones obtained from refining and from concentration of proteins, can generate products with commercial value and/or be used to provide energy for the biorefinery itself.
  • Can soybean seed be used in a biorefinery?
  • Soybean straw or hulls could be used as fuel in boilers to supply energy for the process itself. Other reviews with different approaches concerning the use of soybean seed in a biorefinery platform can already be found in the scientific literature, such as the publications of Abdulkhani et al. and Loman and Ju [ 121, 122 ].
  • How to extract oil from soybean seed?
  • Direct solvent extraction is the most common method used to extract the oil from soybean seed, and hexane is the solvent currently employed. This process essentially consists of three steps: preparation of the seed, extraction of the oil, and desolventizing of the oil and meal [ 14 ].
  • How can oil be recovered from rapeseed & soy oil refining?
  • In the first of these studies, the oil was recovered from spent bleaching clay employed in palm, rapeseed, and soy oil refining processes. The oil was recovered from the spent bleaching earth using double extraction with n -hexane (1:1 w/w) and concentration under vacuum with a rotary evaporator.
  • Why is soybean oil a commercial product?
  • The processes of soybean oil extraction and the concentration of its proteins generate large quantities of residues with components that have commercial value. These residues can be sold with almost no further processing, at a low price (as feed, for instance), or they can be transformed and/or purified in order to increase their value.
  • What is a soybean processing facility?
  • A soybean processing facility, in which refined oil, soy protein concentrate and soy protein isolate are produced, generates residues that if undergo additional industrial operations may result in new products with commercial value.
