  • High selectivity: SFE can be adjusted to be highly selective for vitamin B9 extraction, depending on the operating conditions such as pressure and temperature. This can result in a relatively pure product.
• Challenges
  • High equipment cost: The equipment required for SFE is complex and expensive. This includes high - pressure vessels, pumps, and control systems. The initial investment for enterprises to adopt SFE technology can be substantial.
  • Limited solubility for some components: Although CO₂ is effective for many substances, it may have limited solubility for certain components associated with vitamin B9 in the raw material. This may require additional processing steps or the use of co - solvents in some cases.

4.3 Microwave - Assisted Extraction (MAE)

• Principle: Microwave - assisted extraction utilizes microwave energy to heat the raw material and solvent mixture. The microwaves cause the molecules in the sample to vibrate, which increases the mass transfer rate and facilitates the extraction of vitamin B9.
• Advantages
  • Fast extraction: MAE can significantly reduce the extraction time compared to traditional methods. This can increase the productivity of the extraction process, which is beneficial for enterprises with high - volume production requirements.
  • Energy - efficient: The use of microwaves can be more energy - efficient than traditional heating methods, as it directly heats the sample rather than heating the surrounding environment.
• Challenges
  • Uniformity of heating: Achieving uniform heating throughout the sample can be a challenge in MAE. Uneven heating may lead to inconsistent extraction results and may affect the quality and yield of vitamin B9.
  • Equipment limitations: The microwave - assisted extraction equipment may have limitations in terms of sample size and capacity. For large - scale industrial production, special - designed equipment may be required, which can also increase the cost.

5. Comparison and Considerations for Enterprises
