  • How do you extract residual oil from peanut seeds?
  • Residual oil was collected by subjecting the treated meal to soxhlet extraction for 4 h. The optimal conditions were: enzyme concentration of 7.5% (w/w) in 10 g of peanut seeds, pH 5.0, 50°C, and 5 h with constant shaking at 450 rpm. Centrifuging the mixture at 8500 for 20 min separated the oil with a recovery of 71-73.1%.
  • What is peanut oil used for?
  • In manufacturing, peanut oil is used in skin care products and baby care products. The production process of vegetable oil involves the removal of oil from plant components, typically seeds. This can be done via mechanical extraction using an oil mill or chemical extraction using a solvent.
  • Can enzymatic pre-treatment process extract oil from groundnuts?
  • An experimental study was performed in order to investigate the effect of an enzymatic pre-treatment process for extraction of oil from groundnuts. In the present study celluclast 1.5L was used for the pre-treatment.
  • How is oil extracted?
  • This can be done via mechanical extraction using an oil mill or chemical extraction using a solvent. The extracted oil can then be purified and, if required, refined or chemically altered. Oils can also be removed via mechanical extraction, termed "crushing" or "pressing."
  • Does the concentration of enzyme affect oil recovery from groundnuts?
  • The experimental results showed that the oil yield increased with the increase in concentration of enzyme. The enzyme enhances the oil recovery from the groundnuts. Fig 14: The concentration of enzyme was varied by keep other parameters constants. The oil yield % was more when the enzyme concentration was more.
  • What is a solvent extraction plant?
  • Groundnuts, Coconut, Palm, Grape seed and Rice Bran are typically solvent extracted. Even the most perfect expellers leave at least six percent of oil in the expeller cake. It is possible to recover these losses using a solvent extraction plant. Supercritical carbon dioxide can be used as a non-toxic alternative to other solvents.
