Abstract
The invention relates to methods for preparing a concentrated cannabinoid product optionally also containing an array of terpenes, flavonoids, and other phytoconstituents from a cannabinoid-containing extract feed. The cannabinoid-containing extract feed is contacted with an adsorbent to produce a pre-treated extract which is then subjected to one or more filtration steps, and recovering the concentrated cannabinoid product utilizing an extractant or an evaporator.

A process for preparing a concentrated cannabinoid product, comprising
- contacting a cannabinoid-containing extract feed comprising cannabinoids and a solvent with a solid adsorbent to adsorb large molecule impurities from the cannabinoid-containing extract feed and produce a pre-treated extract;
- contacting the pre-treated extract with a first filter having a 400-5,000 dalton MWCO (molecular weight cut-off) to produce a first retentate comprising large molecular weight impurities and a first permeate comprising cannabinoids;
- combining the first permeate and a liquid phase extractant to form a filtrate extraction mixture comprising an extract phase comprising cannabinoids and a raffinate phase comprising solvent from the cannabinoid-contacting extract feed;
- and
- recovering the concentrated cannabinoid product from the extract phase.

- contacting the pre-treated extract with a first filter having a 400-5,000 dalton MWCO (molecular weight cut-off) to produce a first retentate comprising large molecular weight impurities and a first permeate comprising cannabinoids;
- contacting the first permeate with a second filter having a 150-1,000 dalton MWCO to produce a second retentate comprising cannabinoids and a second permeate comprising small molecular weight impurities, wherein the concentration of cannabinoids in second retentate is higher than the concentration of cannabinoids in the second permeate;
- combining the second retentate and a liquid phase extractant to form a filtrate extraction mixture comprising an extract phase comprising cannabinoids and a raffinate phase comprising solvent from the cannabinoid-containing extract feed;
- and
- recovering the concentrated cannabinoid product from the extract phase.

- adding water to the first permeate to form a water-adjusted first permeate having a water content of from about 20 wt % to about 40 wt %;
- contacting the water-adjusted first permeate with the first filter to produce a second permeate comprising small molecular weight impurities and a second retentate comprising cannabinoids, wherein the concentration of cannabinoids in the second retentate is higher than the concentration of cannabinoids in the second permeate;
