• Disadvantages:
  • The equipment for SFE is relatively expensive, which may require a significant initial investment.
  • The process requires specialized knowledge and technical expertise to operate.

4.2 Ultrasound - Assisted Extraction (UAE)

Ultrasound - Assisted Extraction (UAE) utilizes ultrasonic waves to enhance the extraction process. The ultrasonic waves create cavitation bubbles in the solvent, which helps to break down the plant cell walls and release the quercetin more efficiently.

• Advantages:
  • It can significantly reduce the extraction time compared to traditional methods.
  • The extraction efficiency is relatively high, resulting in a higher yield of quercetin.
  • It can be used in combination with other extraction methods to further improve the extraction performance.
• Disadvantages:
  • The quality of the final product may be affected by the intensity and duration of the ultrasonic treatment.
  • Large - scale application may require additional equipment and energy consumption.

4.3 Microwave - Assisted Extraction (MAE)

Microwave - Assisted Extraction (MAE) uses microwaves to heat the plant material and solvent mixture. The microwaves cause the polar molecules in the plant cells to vibrate, which leads to the rupture of the cell walls and the release of quercetin.

• Advantages:
  • It is a fast extraction method, which can save a significant amount of time.
  • The extraction efficiency is relatively high, especially for heat - stable quercetin compounds.
• Disadvantages:
  • It may not be suitable for all types of plant materials, especially those that are sensitive to heat.
  • The equipment for MAE may be relatively expensive, and the energy consumption can be high.
