Hot FAQ

  • Q Is caffeine soluble in liquid co2?

    A Supercritical CO2 helps act as a solvent to give the coffee bean solvent-like properties to dissolve the caffeine and extract it out of the coffee bean. Because it has a lower viscosity than liquid CO2, allowing it to move through and around the coffee bean more efficiently without too much pressure.
  • Q Is co2 extraction organic?

    A CO2 Botanical Extracts are completely natural and exceptionally pure. These highly concentrated plant extracts are free of solvent residues and impurities such as heavy metals. All CO2 Extracts are oil soluble.
  • Q Why is co2 better than ethanol?

    A CO2 is highly tunable. With CO2 you can vary factors such as time, temperature, and pressure to create different products.  Ethanol products need to go into more stages of refinement to be turned into various products such as distillate.
  • Q Does co2 extraction remove terpenes?

    A CO2 extraction is good for preserving terpenes because it is a cold separation process that can protect delicate plant compounds. Some methods may also use ethanol to help remove terpenes before fully extracting cannabis buds.
  • Q Is co2 extraction better?

    A CO2 extraction is also much better for the environment. CO2 gas is natural, so if it escapes into the air during  extraction it won't do any harm. It can also be recycled, making this method much more sustainable. Since the solvent isn't toxic, people working with this extraction method don't face any health risks.

Difference between Steam Distillation & Supercritical CO2 Extraction

Essential oils derived from the supercritical CO2 extraction of herbs are similar to the oils produced through distillation in that they can be used in aromatherapy and natural perfumery.

Oils derived from steam distillation vary in their qualities depending on the temperatures, pressures, and length of time applied for the process. The CO2 extraction process might thus produce higher quality oils that have not been altered by the application of high heat, unlike the steam distillation process. In CO2 extraction, none of the constituents of the oil are damaged by heat.

Thus, the difference between traditional distillation and supercritical extraction is that instead of heated water or steam, CO2 is used as a solvent in the latter method. The supercritical extraction process operates at temperatures between 35℃ to 50℃, whereas steam distillation operates at temperatures between 60℃to 100℃.

In steam distillation, the molecular composition of both the plant matter and the essential oil are changed due to the temperature applied. On the other hand, a CO2 extract is closer in chemical composition to the original plant from which it is derived, as it contains a wider range of the plant’s constituents.

For example, CO2 Extraction of German Chamomile flowers yields a green extract, because the absence of heat means it was not altered from its natural state or “denatured.” The resulting extract is thus more similar in composition to the original flower than the distilled essential oils is.

CO2 extracts are usually thicker than their essential oil counterparts and often give off more of the aroma of the natural herb, spice, or plant than a distilled essential oil. CO2 extracts have been said to contain more plant constituents than the amount extracted from the same plant using steam distillation.


THE CO2 EXTRACTION PROCESS

·    Pressurized carbon dioxide becomes liquid while remaining in a gaseous state, which means it is now "supercritical." In this state, it is pumped into a chamber filled with plant matter.

·    Because of the liquid properties of the gas, the CO2 functions as a solvent on the natural plant matter, pulling the oils and other substances such as pigment and resin from the plant matter. The essential oil content then dissolves into the liquid CO2.

·    The CO2 is brought back to natural pressure and evaporates back into its gaseous state, while what is left is the resulting oil.

CO2_EXTRACTION

CO2 is colorless, odorless, and can be easily and completely removed by releasing the pressure in the extraction chamber. It is what we exhale and is needed by plants in order for them to thrive, which illustrates its harmlessness when employed in the extraction process. This absence of potentially harmful solvents in CO2 extraction means neither the human body nor the environment is polluted.
