  • The large - scale application of UAE may require some modifications to the existing extraction equipment, which can add to the cost.

3.3. Microwave - Assisted Extraction (MAE)

Microwave - assisted extraction is another modern extraction technology that uses microwaves to heat the seabuckthorn berries or seeds, thereby facilitating the extraction of the oil. The microwaves cause the water molecules in the raw material to vibrate, generating heat and increasing the internal pressure, which helps to break down the cell walls and release the oil.

• Advantages:
  • It has a high extraction efficiency and can significantly reduce the extraction time compared to traditional methods.
  • The energy consumption of MAE is relatively low, making it a more energy - efficient option.
  • The oil obtained through MAE can have a relatively high purity, as the microwaves can selectively heat the components that contain the oil, leaving behind most of the impurities.
• Disadvantages:
  • The equipment required for MAE can be relatively expensive, especially for large - scale production.
  • There is a risk of overheating the raw material, which can lead to the degradation of some of the oil's components and affect the quality of the final product.
