  • Which extraction method produces the highest phenolic content in stevia leaves?
  • Ciulu et al. (2017) also found the highest phenolic content in stevia leaves when extracted with pressurized liquid extraction techniques using 50 % aqueous ethanol at 200°C. Moreover, pressurized hot water (160°C) extraction produced the highest recoveries of all bioactive compounds in stevia leaf ( Kovacevic et al., 2018 ).
  • How is soybean oil extracted?
  • Two common soybean oil production processes are solvent extraction (chemical) and mechanical extraction using a screw press. The most conventional method is to extract oil by mechanical oil processing machines. The oil obtained from screw press, known as crude oil, usually undergoes a filtration process before being consumed as food.
  • How is stevia extracted?
  • In order to increase the value of stevia, the leaves are processed into syrup, powder, or crystals. The process is summarized in Fig. 1. The leaves are first pre-treated, then the glycosides are extracted with the use of conventional methods (solvent extraction) or non-conventional methods (green-assisted extraction methods).
  • What technologies are used to purify stevia extract?
  • Some of the technologies that have been utilized for the purification of the extract are chromatography, adsorption, and membrane technology. The use of chromatography as a separation technique has been utilized to obtain a stevia product with less impurities.
