• How is ginger extracted?
  • To use the active compounds of ginger, they must be released from the ginger root (rhizome) by extraction. Conventional extraction methods for ginger, such as steam distillation or solvent extraction have several drawbacks: They are known to be time consuming, need large amounts of chemical solvents and have limited process capability.
  • How long does it take to extract Ginger?
  • Extraction temperature varies from 50 ¡ãC to 100 ¡ãC, the extraction time usually ranges from 1 h to 5 h, and the total yield ranges from 6.83% to 12.13%. It is worth noting that in alkaline environment, ginger cells are more easily destroyed, and the extraction rate of polysaccharides is higher.
  • How to extract gingerol efficiently?
  • This suggested, a moderate solid to liquid ratio is efficiently extract gingerol as compared to the conventional method. The physical effect, such as power in the UAE system, can enhance the efficiency of the extraction process.
  • How to extract Ginger polysaccharides?
  • Among the different extraction methods, such as SEE, UAE, and EAE, SEE is the most commonly used method for extracting ginger polysaccharides because of its economical nature and convenient use. Extraction temperature varies from 50 ¡ãC to 100 ¡ãC, the extraction time usually ranges from 1 h to 5 h, and the total yield ranges from 6.83% to 12.13%.
  • Does ginger extract oleoresin?
  • Published article in Web of Science database for 10 years with the keyword of ¡°ginger extraction¡±. Ginger contains both volatile (monoterpenes and sesquiterpenes) and non-volatile enriched oleoresin (gingerols, shogaols, paradols, and zingerone) (Kiyama, 2020).
  • How to extract Ginger bioactive compounds?
  • Sarip et al. (2014) studied the extraction of ginger bioactive compounds by pressurized water (3.5 MPa) at different temperature (100¨C200 ¡ãC).
