• What is cottonseed oil plant?
  • The cottonseed oil plant includes cottonseeds pretreatment and prepressing workshop, cottonseed cake solvent extraction workshop and crude cottonseed oil refinery plant. The residual oil rate in the cottonseed meal is lower than 1%. Cottonseeds contain a toxic pigment which called gossypol, of which the content is 0.15%-1.8%.
  • What is cottonseed oil (CSO)?
  • The worldwide cottonseed production in 2019¨C2020 was 43 million metric ton (Kumar et al. 2022). Cottonseed oil (CSO) is the by-product of cotton manufacturer; extracted from the decorticated and delinted cottonseed for their used as edible oil and industrial applications (Orhevba and Efomah 2012; Shah 2017).
  • What is cottonseed oil extraction?
  • Oil extraction is using the organic solvent to extract oil from the pre-pressed cake inside the oil extractor. Multiple oil extractors such as loop type extractor, rotocel extractor and towline extractor can be used for the cottonseed oil extraction plant. After oil extraction, miscella and the solvent containing wet meal are obtained.
  • What is the residual oil rate in cottonseed meal?
  • The residual oil rate in the cottonseed meal is lower than 1%. Cottonseeds contain a toxic pigment which called gossypol, of which the content is 0.15%-1.8%. Cottonseed kernels contain 0.5%-2.5% of gossypol. After processed by the cottonseed oil refinery plant, the gossypol content in the oil is less than 0.01%.
  • What is the oil percentage of Gossypium?
  • Oil percent is also dependent on weather, growth, and maturity of cottonseed, and oil yield also varies from the season to season and place to place of cottonseed varieties. Oil percentage of 20 wild varieties of Gossypium are ranging from 11.22 to 24.82% (Sharif et al. 2019). CSO is extracted by different conventional and non-conventional methods.
  • How to extract CSO from cottonseed?
  • Twenty grams of Lankart-57, RH-112, F-20, K-25, and D-9 cottonseed varieties were used to extract CSO by Soxhlet method using 300 mL n-hexane as solvent at 70 ¡ãC temperature for 5 h, and result shows oil content in the range of 12 to 14.55% (Shah 2017).
