Abstract

Food grade cannabis extracts and methods for their preparation that may reduce or eliminate the anxiety effect that cannabis may have on a user. Embodiments of the methods include providing raw botanical material; providing food grade glycerin; combining the botanical material with the glycerin; blending the botanical material and the glycerin to achieve a homogenous mixture; optionally pre-heating the mixture prior to being agitated; placing the mixture in a sealable container; providing an agitator; securing the container on or within the agitator, agitating the mixture and allowing the mixture to rest at various intervals; heating the mixture and allowing the mixture to cool at various intervals; straining the mixture; pressing the mixture; and then filtering the mixture to remove any remaining particulates to thereby produce a food grade cannabis extract suitable for at least medical use.

Claims (13)

1. A method for preparing a food grade cannabis extract,

comprising the steps of:

providing a raw cannabis material;

combining the material with glycerin;

blending the material and the glycerin to achieve a homogenous mixture without heating the mixture;

agitating the mixture continuously for approximately two weeks without heating the mixture and allowing the mixture to rest after agitation;

heating the mixture to approximately 203 degrees F. for approximately 8 hours and allowing the mixture to cool after heating;

separating a liquid component containing extracted cannabinoids from a solid component of the mixture to produce an extract of the material containing cannabinoids by a three-step microfiltration process;

wherein the three-step microfiltration process utilizes a first filter with a size of approximately 250 microns, followed by a second filter with a size of approximately 190 microns, followed by a third filter with a size of approximately 100 microns; and

recovering the liquid component containing extracted cannabinoids.

2. The method according to claim 1 , wherein agitating the mixture further comprises the steps of placing the mixture in a sealable container, sealing the container, and placing the container upon a motorized agitator.

3. The method according to claim 1 , wherein separating the liquid component from the solid component includes straining and pressing the mixture.

4. The method according to claim 1 , wherein the extract does not include any solvent other than the glycerin.
