CO2 is a clean, efficient way to extract pure plant botanicals, hops and cannabinoids. “We’d heard about people doing it with the cannabis industry, but to have someone doing it for hops here in Calgary, it was just the coolest thing ever”

Week 5 Note: Essential Oils (terpenes…) and Oleoresins… Are they different?
Let’s continue the discussion

We are going to talk about the difference between terpenes…. Most commonly called Essential oils and oleoresins which are usually named by their scientific name for each botanical/spice. We are going to focus on the commonly called “spices” defined as strongly flavored or aromatic substances obtained from plants (usually tropical plants) and commonly used as condiments for their flavour and preservative qualities.

Individual components of spices have been study in several different areas. The volatile components of spices make the essential oil of the particular spice and are responsible for the aroma; the non-volatile part make the oleoresins which contribute to the bitter/pungent part of the spice and also may contain medical/health/therapeutic properties.

The essential oil is classified in four major groups: monoterpenes, diterpenes, sesquiterpenes and oxygenated compounds (esters, ketones, alcohols, ethers). This classification is mostly based on chemical structure that we wont cover in this note….. let’s leave that to the chemist for now. It is important to note that the lack of any of the components (or large change in quantities) will affect the aroma of the specific spice.

The non-volatile components are large molecular weight (in comparison with essential oils) structures and are mostly fatty acids, resins, paraffins, waxes and alkaloid. They are viscous and resinous and contain the components that are responsible for medical attributes of the spice.

Supercritical CO2 extraction works for both, essential oils and oleoresin. The extract obtained from supercritical CO2 extraction have more top notes, no degradation, more shelf life and better aroma and blending characteristics than steam distilled or solvent extracted products. In some cases, secondary purification is required so generate more pure components when needed, specially for specific aromas or for nutraceutical/natural health products.

Please note that none of this information is of my own, all these information from the weekly notes come from several sources of scientific information and it is intended for personal education purposes for our followers and people in the industry interested on clear knowledge. If you are interested in deep information, please let us know and we will give you some references for your own study and understanding.

Week 4 Note:

In this week’s note, we will introduce why supercritical CO2 is such a great solvent for the production of natural extracts. In note 1, we reviewed what supercritical CO2 is… We recommend to read that again as background for this note.

Supercritical CO2 can dissolve natural molecules (and complex mixture of molecules) depending on their molecular size, polarity, functional groups. Development of a SCFE process requires knowledge of selectivies (what CO2 likes or not); these selectivities can be estimated from pure component experimental data due to the absence of thermodynamic models for predictions. Botanicals contain dozens of different components which makes it more challenging 1) the full extraction of the complex mixtures in the plant and 2) the estimation or prediction of SCFE performance based on the known selectivities. Therefore, there is no substitute for EXPERIMENTAL measurements of solubility data of natural components in supercritical CO2. Pilot performance tests are very important to be able to identify process conditions and optimize extraction getting the best benefit of supercritical extraction without compromising technical and economical sources including the equipment.

What is one of the most important thermophysical properties of CO2 for supercritical fluid extraction?
Density: the solvent capacity at the supercritical fluid state is dependent on density. There is a sharp variability of density with pressure and temperature at the supercritical state… this makes supercritical CO2 very unique. By regulating pressure and temperature we control the desired density of our SC CO2 in the process. However, we need knowledge of these variations. Thermodynamic equations give good representation of this property, especially P-R EOS (this equation is for the chemical engineer reader)…. There are thermodynamic charts available from which we can read the density of CO2 at different pressures and temperatures (To be expanded on later in a coming weekly note). The sharp variability of density with process conditions allows the fine-tuning of solvent power of the desired components from a feed material. In general, it is possible to produce multiple products in the same SCFE plant, taking advantage of the possible variation of solvent properties that one may achieve with supercritical CO2….

We are so proud to have set up the steps for the hop extract industry in Canada to make a more sustainable and profitable brewery industry. Welcome to the new hop extract producers, hope we make a great industry together for the better for all breweries in AB, BC and Canada and their tasty beers!! Cheers!
