MAE uses microwave energy to heat the plant material, which accelerates the extraction process. It is a fast and efficient method, but it requires careful control of the microwave power and time to avoid degradation of the toxins.

7. Ultrasonic-Assisted Extraction (UAE):
UAE uses ultrasonic waves to break down the plant cell walls, releasing the toxins into the extraction medium. This method is non-thermal and can be used for heat-sensitive toxins.

8. Enzymatic Extraction:
Enzymatic extraction involves the use of enzymes to break down the plant material and release the toxins. This method is gentle and can be used for delicate toxins that may be damaged by other extraction methods.

9. Liquid-Liquid Extraction (LLE):
LLE is a technique where two immiscible liquids are used to separate the toxins from the plant material. The toxins are more soluble in one of the liquids, which is then separated from the other.

10. Chromatographic Techniques:
Chromatography is a method used to separate complex mixtures of toxins. It can be used after initial extraction to purify and isolate specific toxins.

Each of these methods has its advantages and limitations, and the choice of method depends on the specific requirements of the toxin extraction process. It is often necessary to combine several methods to achieve the best results.
