Microwave Assisted Extraction Method

What is Microwave Assisted Extraction (MAE) primarily used for?

• Synthesizing new compounds 

• Extracting bioactive compounds efficiently 

• Heating solvents without extraction 

Which factor significantly impacts the efficiency of MAE?

• Time of day 

• Color of the solvent 

• Power level of the microwave 

One of the primary advantages of MAE over traditional extraction methods is

• It uses more solvents 

• It requires less extraction time 

• It has a higher energy cost 

Which type of solvent is typically more effective in MAE?

• Viscous solvents 

• Non-polar solvents 

• Polar solvents 

In MAE, why is smaller particle size beneficial?

• It reduces the microwave absorption 

• It increases the extraction surface area 

• It prevents compound degradation 

Which of the following is a limitation of MAE

• It cannot heat solvents 

• It is only effective for solid materials

• It may degrade certain compounds 

MAE aligns with green chemistry principles mainly because it

• Increases solvent consumption 

• Reduces energy usage and waste 

• Utilizes non-recyclable solvents 

Microwave energy in MAE enhances extraction by

• Eliminating the need for a solvent 

• Heating the plant material and solvent quickly 

• Reducing pressure in the solvent 

Which bioactive compounds are commonly extracted using MAE due to their sensitivity to heat?

• Proteins 

• Antioxidants 

• Carbohydrates 

What must be considered when scaling up MAE for industrial use?

• The color of the microwave oven 

• Time of microwave exposure 

• Equipment design and cost
