• What is the yield of ginger oil?
  • Ginger oil’s yield is varying from 1.0 to 3%, depending upon the source of rhizomes . In addition to the essential oil’s yields, the chemical compositions of ginger oils are affected from the source of rhizome, freshness or dryness and extraction methods.
  • How much oleoresin is in a ginger rhizome?
  • Ginger oleoresins comprise approximately 20¨C30 % of volatile oil, 10 % of fixed oil, 50¨C70 % of pungent resinous matter but only accounts for 4¨C10 % of the total dry weight of the rhizome. Thus, there is a significant amount (by weight) of spent ginger waste produced from industries such as herbal medicine or beverages ( Wiastuti et al., 2016 ).
  • What is ginger essential oil?
  • Ginger essential oil is extracted from ginger rhizomes, which the chemical composition of ginger oils influences from geographical region, extraction methods, freshness or dryness of rhizomes.
  • How is ginger oil made?
  • Ginger oil can be produced in a ramification of strategies from ginger rhizomes. It may be received conventionally, traditionally, or via hydro-distillation (Clevenger-kind apparatus) . The essential oil of Zingiber officinale is the yellowish ethereal oil made from ginger rhizomes, which debts for round 1 to a few% of a rhizome.
  • Can industrial Ginger waste be used as a biorefinery?
  • Herein, the valorisation of spent industrial ginger waste as a source of chemicals, materials and (bio)energy in order to establish a preliminary biorefinery concept is reported ( Fig. 1). The aims are to i. Recover residual oils (extractives) by Soxhlet (heptane) or supercritical CO2 entrained with 10 % ethanol as co-solvent. ii.
  • What are the components of simultaneous distillation of ginger oil?
  • Zingiberene + zingiberol (38.9%), ar-curcumene (17.7%), ¦Â-sesquiphellandrene+¦Â-bisabolene (11%), ¦Â-phellandrene (4.9%) were the main components of simultaneous distillation extracted ginger oil from fresh rhizome (Bangalore market) .
