[0033] Figure 1 of the drawings is flow diagram of an extraction process of the present invention; and

[0034] Figures 2-3 of the drawings are product characteristics / properties of materials of the present invention.DETAILED DESCRIPTION OF THE INVENTION

[0035] While this invention is susceptible of embodiment in many different forms and applications, there are shown in the drawings and described herein in detail several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated.

[0036] It will be understood that like or analogous elements and / or components, referred to herein, may be identified throughout the drawings by like reference characters. In addition, it will be understood that the drawings are merely schematic representations of one or more embodiments of the invention, and some of the components may have been distorted from their actual scale for purposes of pictorial clarity.

[0037] The present invention is directed to cannabinoids as well as novel methods and systems for producing cannabinoids with enhanced bioavailability for maximizing absorption when orally and / or topically administered.

[0038] The present invention utilizes multi-step methods for preparing a cannabinoid containing solution / composition / material, generally comprising, consisting essentially of and / or consisting of the steps of: (a) providing a biomass containing cannabinoids; (b) extracting cannabinoids from the biomass, wherein the extracted cannabinoids are substantially free from a solvent; (c) associating the extracted cannabinoids with a carrier liquid to form a cannabinoid infused carrier liquid; (d) associating the cannabinoid infused carrier liquid with a solid / powder to form a cannabinoid infused carrier powder; and (e) associating the cannabinoid infused carrier powder with water to form liposomes containing cannabinoids in an aqueous solution. Additional details pertaining to each step are provided herein below.

[0039] In a first step of the present invention, biomass containing cannabinoids are provided for subsequent processing. Non-limiting examples of suitable biomasses comprise Cannabis indica, Cannabis sativa, Cannabis ruderalis, and mixtures thereof. It will be understood that other medicaments and / or adjunct agents (i.e., colorants, flavorants, preservatives, slip agents, viscosity modifiers, rheology modifiers, pH modifiers, minerals, vitamins, etcetera) can be utilized with the cannabinoid containing material.

[0040] In a second step of the present invention, cannabinoids are controllably extracted from the biomass. In this step, the extracted cannabinoids are substantially free (i.e., less than 5 ppm) and / or free from a solvent (e.g., a hydrocarbon containing solvent) used during the extraction.

[0041] As is shown in Figure 1 , and in one embodiment of the present invention, the extraction process 10, utilizes a closed loop extraction system. The system includes one or more material columns 12, color remediation column 14, collection vessel 16, filter dryer 18, heat exchanger 20, recovery pump 22 and solvent tank / vessel 24. The solvent (e.g., an aliphatic hydrocarbon, butane, propane or butane / propane mixture) resides in the solvent tank. The fluid moves from solvent tank 24 to material column(s) 12, to color remediation column 14, and then to collection vessel / honeypot 16 for the injection, and back to the solvent tank via the filter dryer and heat exchanger for the recovery to complete the closed-loop system.

[0042] Preferably, upon starting this process step, a vacuum is created in the entire system, via vacuum pump 26, to get rid of any moisture that might exist. All the components other than solvent tank 24, which is in isolation from the vacuum or negative pressure, are provided with vacuum; this also helps create positive pressure for the injection step of the system. Also, vacuum is important to eliminate any moisture from the system that might contaminate the extraction process.

[0043] Once the system of operational, cold solvent is injected from the solvent tank to the material column, where it absorbs the essential oils out of the biomass / plant matter. As the solvent enters the material column, it is sprayed through a spray ball. The material loaded into the material column is soaked with the solvent. Next, the mixture of the solvent and oil flows through the inline remediation column and into the collection vessel. It is preferred that the recovery does not start until the user can visualize the flow into collection vessel with the help of sight glasses. The solvent / oil mixture is then heated in the collection vessel / honey pot or dewax column so that the solvent can evaporate and leave the vessel. This is attained by heating the jacket of the collection vessel, as well as the filter dryer. Once this is achieved, the solvent starts evaporating and leaves the vessel. The solvent then passes through the filter dryer to get rid of any residual moisture and / or impurities. Next, the working solvent passes through the recovery pump to a heat exchanger. At the heat exchanger, the solvent is cooled to subzero temperature with the help of a chiller. The cold solvent is then injected back to the solvent tank to complete the closed loop cycle. At the heat exchanger, the solvent is cooled down and travels back to the solvent tank. Next, the extracted product gathered from the collection vessel / honey pot is placed in a vacuum oven. The vacuum oven is set to 80 degrees Fahrenheit with a minimum vacuum of -29mm Hg is achieved. The extracted product is left in the oven for up to 24 hours and then tested for any solvents. If any exist, the extracted product is placed back in the oven and a vacuum is pulled again until no solvent is detected via gas chromatography (GC) or other analytical instrumentation.

[0044] In a third step of the present invention, the extracted cannabinoids are associated with and / or dissolved into a carrier liquid to form a cannabinoid infused carrier liquid. Non-limiting examples of carrier liquids include edible lipids, medium chain triglycerides, vegetable oil, coconut oil, corn oil, soybean oil, beef tallow, lard, palm oil, sunflower oil, avocado oil, hemp seed oil, and / or olive oil.

[0045] In a fourth step of the present invention, the cannabinoid infused carrier liquid is associated with a solid or powder, preferably free-flowing, to form a cannabinoid infused carrier solid / powder. Non-limiting examples of solids / powders include those comprising the structure:- wherein Ri-R7are the same or different and selected from the group consisting of H; OH; and an alkyl, cycloalkyl, polycycloalkyl, heterocycloalkyl, aryl, alkaryl, aralkyl, alkoxy, alkanoyl, aroyl, alkenyl, and / or alkynyl group containing approximately 1 to approximately 25 carbon atom(s), wherein the carbon atom(s) may be a linking group to, or part of, a halogen, a N, O, and / or S containing moiety, and / or one or more functional groups comprising alcohols, esters, ammonium salts, phosphonium salts, and combinations thereof.

[0046] In a preferred embodiment of the present invention, the solid or powder comprises the structure:and congeners and derivatives thereof.

[0047] In one embodiment of the present invention, the step of associating the cannabinoid infused carrier liquid with a solid or powder includes the step of plating the cannabinoid infused carrier liquid onto a water soluble free-flowing powder consisting of maltodextrin to form a homogeneous cannabinoid infused carrier powder via mechanical mixing selected from the group consisting of a v-blender, a z-blade mixer, an unheated tumbler, a heated tumbler, a vertical mixer, a horizontal mixer, and combinations thereof.

[0048] In a fifth step of the present invention, the cannabinoid infused carrier powder is associated with and / or dissolved into an ingestible polar solvent (e.g., water) to form liposomes containing cannabinoids in a solution.

[0049] Product characteristics / properties of materials prepared using the systems and methods of the present are provided in Figures 2 and 3.
