Abstract
The presently disclosed subject matter is directed to a system and method of extracting bioactive agents from biomass using continuous microwave-assisted extraction. The disclosed system includes a plurality of microwave modules that exposes the biomass to continuous microwave energy, and an extraction module to extract bioactive agents from the biomass. In some embodiments, the biomass is exposed to subcritical water treatment in the microwave modules. The disclosed system enables bioactive agent to be extracted effectively, in a relatively short period of time compared to conventional extraction methods and allows for an enhanced extraction yield.
Claims7
A continuous microwave assisted extraction system comprising:
- one or more flow-through microwave processing units,
- wherein at least one of the one or more flow-through microwave processing units is a subcritical water microwave assisted extraction unit that uses a polarity of water in a subcritical range in lieu of chemical solvents to extract one or more bioactive agents from biomass;
- one or more blending units comprising a mixing or blending device;
- one or more extraction vessels comprising a separation element to separate solid from liquid;
- and
- a series of conduits that connect the flow-through microwave processing units, blending units, and extraction vessels;
- wherein the extraction system optionally comprises:
- one or more homogenization units comprising a chopping or slicing device;
- or
- one or more finishing units comprising an evaporator, dryer, or both;
- or
- both one or more homogenization units and one or more finishing units;
- and
- wherein the extraction system is configured to provide for continuous extraction.
