Testing CBD oils

Testing CBD oils

To produce CBD oil is just a first step. It is ensuring that a delivered product is of the top quality what is essential – and here a thorough examination procedure comes into play. Contrary to the popular opinion, it is not enough to analyse just the final stage of the production process, as it can often result in a various or even random products. The professional manufacturer not only should control the raw input material before the extraction, but also examine the plants while they are still growing, in order to be able to choose the best time for harvest.

Supercritical CO2 extraction (SFE) (2/2)

Supercritical CO2 extraction (SFE) (2/2)

Supercritical CO2 extraction technique guarantees natural composition of the extract and does not cause degradation of its precious ingredients. This is possible, first and foremost, due to the fact that this technique does not involve the use of high temperatures that are often required for solvent extraction (especially when crude, amateurish methods such as distillation or solvent evaporation of solvent by heating it are at play), so no thermal degradation will occur [1]. Thermal degradation will result in more than just a change of extract’s color from golden (which is natural for cannabinoids) to brown or even black. What really happens is invisible – and truly disaterous – oxidation, isomerization or polymerisation processes that the elevated temperatures induces can cause the decay of many valuable components of the extract. Even worse, these processes can often turn beneficial ingredients into harmful ones. Terpenes can serve as an example – once oxidated they can acquire irritant, allergic and pro-inflammatory properties [2]. Of course, the SFE process can also be carried out at higher temperatures (which in this case means any above 31 ° C), but even then oxidation processes will not be initiated due to the simple fact that there is no oxygen present in the system , just pure and completely inert carbon dioxide.

Supercritical CO2 extraction (SFE) (1/2)

Supercritical CO2 extraction (SFE) (1/2)

CannabiGold oils are obtained by supercritical carbon dioxide extraction (SFE) technique. The abbreviation SFE stands for Supercritical Fluid Extraction and means exactly this – extraction with fluids in supercritical state. “Fluid”, hence (at least theoretically) any substance can be converted to supercritical fluid state. In practice, for most substances obtaining such state requires such extreme pressure and temperatures that only a few of them, including carbon dioxide, are viable for SFE procedures. More »

What are Cannabinoids?

What are Cannabinoids?

Cannabinoids are natural compounds found in cannabis plants – both in hemp (Cannabis Sativa L.) and in Cannabis Indica strains. Cannabis contains about 480 different substances, 80 of which are counted among cannabinoids. Most of the cannabinoids (and all of those found in fibrous-grade hemp) are deprived of any psychoactive properties, many show a variety of health benefits. More »
