Novel extraction methods
Novel extraction methods are also known as green methods. Green
extraction can be defined as follows: Green extraction is based on
extraction methods that reduce energy consumption, allow the use of
alternative solvents and renewable natural products. Also ensure the
safety of the process and the production of a quality product. In
general, these types of extraction methods have the following
characteristics [56].
- selection of varieties and renewable plant resources.
- Use an alternative solvent.
- Reduce energy consumption.
- Production of co-products instead of waste.
- ensure the process is safe, robust and controlled.
- Production of biodegradable extracts without contamination.
These green methods have led to considering application of new methods
include Supercritical fluid extraction (SFE), Subcritical extraction
liquids, Enzyme-assisted extraction, Ultrasound-Assisted
Extraction (UAE), Microwave-assisted extraction (MAE), (PEF) Pulsed
electric field (PEF), Pressurized liquid extraction (PLE) and High
voltage electrical discharge (HVED) for the extraction of essential oil.
