  • Can ethanol be used as a solvent for soybean oil extraction?
  • It was possible to use single-batch experimental assays in laboratorial-scale to evaluate key parameters for soybean oil extraction using ethanol as solvent. Such parameters may assist the design and development of continuous and countercurrent extractors adopting fixed bed columns in series as contact stages.
  • How is soybean oil extracted in a continuous and countercurrent process?
  • Extraction of soybean oil in a continuous and countercurrent process. Multistage extraction was experimentally reproduced from batch single-stage assays. The process efficiency was mainly limited by the oil solubility in the solvent. The minimum solvent mass flow and the number of ideal stages were calculated.
  • How is oil extracted from soybeans?
  • Due to the moderate oil content (18 ¨C 23%mass) , it is mandatorily recovered from soybeans by solvent extraction . Currently, industries adopt a continuous-countercurrent-multistage extractor for oil extraction from vegetable oilseeds.
  • What is soybean oil purification?
  • Soybean oil purification, as used here, refers to the purification processes individually referred to as degumming, refining, bleaching, and deodorization. Each process is designed to remove certain minor components. The product of the purification processes is identified as RBD (refined, bleached, deodorized) soybean oil or soybean salad oil.
  • What is the water extraction profile of soybean collets?
  • The water extraction profile is very similar to the oil one. Moisture existing in the fresh soybean collets (6.22 ± 0.06%) was progressively transferred to E, reaching about 3.5% water in the final extract phase ( E1 ). Fig. 5 d shows the residual oil content in R throughout the stages.
  • How were soybeans used in solid-liquid extraction assays?
  • Soybeans were cracked, dehulled, flaked, expanded, and kindly supplied by the Brazilian Company Caramuru Alimentos S.A (Itumbiara/GO, Brazil). The expanded soybean mass (soybean collets) was used as feed in the solid-liquid extraction assays. This material was the same as the one prepared by the industry for soybean oil extraction with hexane.
