Top Global CBD Oil Suppliers

According to ThomasNet, the top global CBD oil suppliers by revenue are Canopy Growth Corporation, Tilray, Elixinol, GW Pharmaceuticals (recently acquired by Jazz Pharmaceuticals), and Aurora Cannabis.

With almost double the revenue as the nearest competitor (which can be seen at the bottom of the page), we expected Canopy Growth to show the highest number of global searches, but instead, we saw Tilray take center stage as the company with the most searches.

Tilray, a Peter Thiel backed cannabis company, is the first cGMP certified medical cannabis producer of dried flower and extracts. Their recent spike in search interest could be related to the popular Reddit forum, /r/wallstreetbets, singled out the stock for being heavily shorted. Along with its December 2020 merger with Aphria, this may have been a large contributor to its price surge within the last 90 days, and subsequently, it’s increase in search popularity.

In the world of manufacturing, things move quickly. The manufacturer’s goal is to manufacture their product with the target quality in the proper quantity with as little waste possible. Many manufacturing outlets will do their quality control before a process starts and after the process ends, but what about while something is being created?

Welcome to The ABCs of cannabinoid manufacturing

Part 5: Extraction Methods

The separation of the wide array of compounds in Cannabis sativa is becoming more important as regulations on cannabinoid containing products become more stringent. There are a few common methodologies used for extraction in the cannabis industry.

Depending on the intended final product, incoming processing can include separation of the flower portions with the highest concentration of cannabinoids and terpenes. Then the extraction of the terpenes and the cannabinoids can begin. Though mechanical separation methods exist, this article will focus on the most common solvent-based extractions: hydrocarbon, ethanol and super-critical CO2 . Solvent extraction methodologies have been around for millennia since the ancient Egyptians made tinctures by soaking herbs in ethanol. Tinctures are created by putting the herbs into a liquid, usually alcohol, to extract the flavors, healing components, etc.

Cannabis Manufacturing

Basic Solvent Extraction

The basic solvent extraction is based on historical methods, although we have made technological advances to help us control the processes over the centuries. Today, common organic solvents include ethanol [1], butane, and propane. [2] Water extraction will not be covered in this article due to its low yields of cannabinoids and terpenes.

Alcohol extraction uses ethanol and is one of the most common and efficient methods of extracting the cannabinoids. The initial step is to soak the raw material in Ethanol to remove the trichomes. The polar end (-OH group) of the molecule helps dissolve the hydrophilic compounds, such as chlorophyll. The non-polar end (C2¬H5) helps to dissolve the hydrophobic compounds such as the plant waxes, oils, cannabinoids, and terpenes.

The process can be done in either warm or cold ethanol. In warm or room temperature ethanol, the cannabinoids dissolve quickly leading to a high yield of cannabinoids. However, the warm ethanol extraction process also dissolves plant lipids including the chlorophyll, which causes a strong bitter taste. By dropping the temperature of the ethanol to less than -30˚C (-22˚F), you decrease the solubility of all the compounds leading to a much slower dissolution of the products into the ethanol. However, it is also below the freezing point of many plant waxes which means that many of the compounds will be solids. The impurities separate from the cannabinoids and can be easily removed.

Hydrocarbon extraction

Hydrocarbon extraction generally uses either propane or butane. Propane and butane are small hydrocarbons, made only of carbon and hydrogen atoms, that are non-polar with low boiling points, (-44˚F and 32˚F, respectively) [3]. The initial extraction washes the raw material with the cold hydrocarbon.

The non-polarity of the molecules helps easily dissolve the cannabinoids, waxes, fats and lipids. Unlike ethanol, there is no polar end to help with the dissolution of certain undesired compounds such as chlorophyll. The terpenes are also easily dissolved in the hydrocarbons, though the flavonoids have limited solubility. The hydrocarbons with the products of interest can be separated by flowing the mixture into a separate area and raising the temperature. [4] With low boiling points, the hydrocarbons evaporate at -44˚F (Propane) and 32˚F (Butane) leaving behind the waxes, fats, lipids, cannabinoids, and terpenes.

Final extraction method

After the separation of the hydrocarbons from the extract, the propane or butane can be recirculated though the biomass creating a closed-looped system. The result is an extract that is relatively free of inactive plant matter such as chlorophyll. Hydrocarbon extraction is losing popularity primarily due to regulations for handling propane/butane and stigma attached to a using a hazardous chemical for the extraction.

The final extraction method uses super-critical CO2 . Outside the cannabinoid industry, supercritical extraction methods are used for the production of high-quality hempseed oil, extracting caffeine from coffee, removing pesticides from agriproducts, etc. [5].

At standard temperatures and pressures (room temperature and sea-level atmospheric pressure), all molecules are in their natural state of matter: solid, liquid, gas, or plasma. One can change the state of matter by changing the temperature or the pressure or both. A good example of this would be creating ice cubes in your freezer. Without changing the pressure, you can turn the water into ice by lowering the temperature.

When modulating the temperature and pressure of a system, liquids and gases can hit a critical point where they exhibit characteristics of both liquid and gas. They take up the entire space (more compressible) like gases and have liquid-like densities. This is called a supercritical fluid. [7]. Figure 2 shows the phase diagram of Carbon Dioxide (CO2 ). Using CO2 has several advantages, it is nonflammable, non-toxic, relatively inert, abundant and inexpensive [8, 9].

Experimental phase diagram of CO2

The other main advantage is that at a temperature of 31˚C, you can maintain the supercritical liquid at 74 bar [6, 7]. The various components of cannabis have different solubilities at different temperatures and pressures, thus allowing a clean extraction of the target compounds. However, one study has shown that the concentrations of different products can be extracted at different rates, so the extract should be analyzed [2, 8, 10].

Part 6: Overview of Extraction Methodologies & Monitoring

The separation of the wide array of compounds in cannabis sativa L. is becoming more important as regulations on cannabinoid containing products develop and become more stringent. There are a few common solvent methodologies used for extraction in the cannabis industry.

Alcohol extraction uses ethanol and is one of the most common and efficient methods of extracting the cannabinoids. The process can be done in either warm or cold ethanol. In warm or room temperature ethanol, the cannabinoids dissolve quickly leading to a high yield of cannabinoids. For warm ethanol extraction, the initial step is to soak the raw material in Ethanol to pull off the trichomes. In cold ethanol extraction, the first step is to chill the ethanol down to -40˚C before introducing the cold ethanol to the cannabis biomass.

Afterwards, the mixture is collected, filtered and the solvent is evaporated and reclaimed. In warm ethanol extractions, additional purification steps, such as winterization, are necessary. The biggest issue with scaling up this particular process is the ethanol itself. Because of its flammability, it is rated as a Class 1 Division 2 solvent, which limits the amount of Ethanol that can be stored on a particular site.[1] The evaporation of the solvent from the enriched liquid also requires specialized equipment to efficiently evaporate the ethanol to be reused in a closed-loop process.

ABCS Of Cannabinoid Manufacturing

Hydrocarbon extraction generally uses either propane or butane. Similar to the cold alcohol method, the hydrocarbon solvent is cooled down to below it’s boiling point so that it is in liquid form. The initial extraction washes the raw material with the cold hydrocarbon solvent. The hydrocarbons with the products of interest can be separated by flowing the mixture into a separate area and raising the temperature. [2] With low boiling points, the hydrocarbons evaporate well below the point of degradation of some of the more volatile compounds, leaving behind the cannabinoids, terpenes, flavonoids and waxes.

After the separation of the hydrocarbons from the extract, the propane or butane can be recirculated though the biomass creating a closed-looped system. The result is an extract that is relatively free of inactive plant matter such as chlorophyll, fats and lipids. Inline de-waxing can also be accomplished using the same hydrocarbon solvent thereby entirely removing the need for winterization.

Overview of Extraction Methodologies & Monitoring

Despite this advantage, hydrocarbon extraction is losing popularity for several reasons including, but not limited to, regulations for handling propane/butane and stigma attached to a using a hazardous chemical for the extraction. [3] Similar to alcohol extraction, hydrocarbons are flammable, but they are more stringently classified as Class 1 Division 1. Another difficulty is that many places are banning the use of hydrocarbon extraction, making the setup and scale-up of this process unachievable.

In the next issue, we’ll discuss the final extraction method: supercritical CO2. It’s many advantages make it a promising option for those looking to dive into extraction.
