Advantages and disadvantages of conventional and non-conventional extraction methods

Methods	Advantages	Disadvantages
Conventional
Maceration	Simple method and low cost	High extraction time, low yields and use of organic solvents
Soxhlet	Simple method	High energy consumption and use of organic solvents
Hydrodistillation	Organic solvents are not required	Hgh temperatures, high energy consumption and high extraction time
Non-conventional
Supercritical fluid	Extraction is rapid, selective and does not require additional cleaning	Temperature changes and specialized equipment
Pressurized liquid	Rapid extraction and reduced consumption of solvents	High temperatures and pressure
Ultrasound assisted	Low extraction time, low energy consumption and high yields	Use of organic solvents
Microwave assisted	It can be done with or without the addition of solvents	Specialized equipment
Pulsed electric field	Low extraction time and high yields	Use of solvents and energy consumption
