PROCESS

Do YOU know where your CBD is coming from? We know where ours comes from, has been, and is going.

Because we are vertically integrated, at no point in the production process does our biomass or derived bulk CBD exit our system. We know by lot code and batch, precisely where each product comes from and can verify its origins via associated testing and reporting.

At Kadenwood BioSciences, we obtain certificates of analysis (COAs) for every product we sell. In the case of CBD, a COA will include measures of cannabinoid content and other tested compounds, such as pesticides, mold, and heavy metals. A 2017 study found that almost 70% of CBD products sold online aren’t labeled correctly, having either considerably less or more CBD than advertised. Rest assured, with Kadenwood BioSciences you’ll know precisely what you are buying.

crute oilGenetics and Seed Production.

Said plainly, high-quality CBD hemp comes from high-quality hemp genetics. Our proprietary hemp strains create fully-feminized seeds that produce high CBD hemp plants that are the finest in the industry. We own award-winning genetics and want to work with you to turn them into high-yielding, predictable, and reliable crops.


dryingDrying and Prepping Biomass.

The CBD content from a hemp plant is primarily found in the flower and on the leaves. However, when a plant is harvested it also has stems and stalks which are very fibrous, of low CBD content, and generally difficult to manage in the extraction process.

Therefore, to increase processing efficiencies, the first step is to dry the hemp plant, which is typically done by hanging and ensuring proper airflow around the plant. Once dried, the leaves and flower buds can be easily shucked away from the stalks and stems.

Finally, the dried leaves and flowers are milled to a processor’s specification and stored in climate-controlled super sacks until delivered to an extraction facility where the desired cannabinoid compounds are removed.


crute oilExtracting to a crude oil.

Once the biomass has been dried, shucked, and milled, we can extract the desired cannabinoids and terpenes. The first stage in this process is commonly referred to as a crude oil. It’s called “crude” because it has varying concentrations of CBD (usually between 50-75%), many other cannabinoids and terpenes, as well as, undesirable compounds such as fats, waxes, and chlorophyll.

Put simply, a solvent is added to the biomass, and heat and pressure are manipulated until the chemical compounds are separated from the plant cells and fibers. This is similar in concept to what happens when running hot water over ground coffee beans and then put through a filter. The result is that the coffee’s oils, caffeine, and flavor profiles are extracted into the solvent (water). The most common solvents utilized in the extraction of CBD are ethanol and CO2.


dryingWinterization and Recovery.

It is very difficult (if not impossible) to extract CBD from a hemp plant without also removing undesirable compounds such as lipids and waxes. In order to remove the undesirable compounds, the extract is mixed with 100% ethanol and placed in a deep freezer. As it cools, lipids and waxes will solidify while the ethanol, CBD, and terpenes remain fluid.

The remaining ethanol is evaporated from the cannabanoids by gently warming the solution. Given that ethanol has a very low vaporization point, this can be done without high heat and, therefore, does not degrade the desired compounds.

What is left is oil that is completely plant-derived and contains cannabinoids (CBD and others) as well as any terpenes that were extracted from the plant.


dryingRefinement to Distillate and Isolates.

The variation in concentration of crude oils along with the inclusion of other cannabinoids, terpenes, etc., makes formulation of consumer goods very difficult and inconsistent. For that reason, an additional step that refines the crude oil into a distillate or isolate is needed.

CBD oil can be refined into many different end products including full-spectrum oils (may include THC), broad-spectrum oils (non-detectable THC), or isolated CBD (CBD only). Water-soluble and nano formulations are also available; each has benefits and drawbacks depending upon the end use application.


Let’s talk testing.

There are multiple points during the supply chain from seed to shelf that should be tested to ensure safe, reliable, high-quality CBD. Our testing procedures begin well before the extraction process begins to ensure the highest quality end product.

  • SOIL: First, we test the soil. A hemp plant will draw everything it needs from the ground, along with things it doesn’t, like heavy metals and residual pesticides.
  • WATER: We also test the water to ensure optimal plant health. A plant under duress can “go hot” or even become hermaphroditic which can produce unwanted pollinated males or wild seed and disrupt the downstream processes.
  • SEEDS: Then, we test our seeds, genetics, and strains, verifying germination rates and days to maturation, among other things.
  • PRE + POST HARVEST: During growing we test the plant for CBD content at pre- and post-harvest to ensure the crop has not gone “hot”, meaning it is in compliance of regulated THC levels, and again lacks the presence of heavy metals and pesticides.
  • PROCESSING LEVEL: Finally, at the processing level we test every aspect from our crude to final CBD products such as our CBD Broad-Spectrum oils and isolates with multiple third-party testing facilities with certificate of analysis (COA) before we bring those to market.
