Abstract
The present method applies Pulsed electric fields adding additional control variables for the extraction of target organic compounds from plant material. A current method of extraction of target Cannabaceae plants during processing provides methods to accelerate drying and extraction of these oil rich plants where the pre-removal of water is beneficial aiding in decreased process times. The methods include applying electric fields to the plant material to accelerate the dehydration, and the extraction of target organic compounds.
Claims9
A method of extracting cannabinoids from cannabis consisting essentially of the steps of:
- (a) harvesting and cutting live cannabis;
- (b) applying a pulsed electric field process to the cannabis at a range of 0.1-12 kJ/kg and a voltage of 20,000 volts-30,000 volts which produces the creation of nano-pores on the surfaces of the cannabis of a size enabling water to traverse through the nano-pores while retaining desired cannabinoids from the cannabis;
- (c) pressing the cannabis, simultaneously or consecutively, with a weight, expediting egression of water from the interior of the cannabis through the nano-pores;
- (d) drying the cannabis to less than 10% wt;
- (e) performing super critical fluid extraction process on the freshly cut cannabis using a solvent selected from the group consisting of carbon dioxide, ethanol, clorofloural carbon, propane and butane, which expedites penetration of the solvent into the freshly cut cannabis via the created nano-pores and extracting the desired cannabinoids from the cannabis, wherein the size of the nano-pores is controlled by simultaneously applying the kJ/kg and voltage in step (b) and the weight in step (c).
