Afin de produire des produits CBD<\/a> de haute qualit\u00e9, l’extrait CBD<\/a> doit d’abord \u00eatre extrait de la plante de chanvre. Ceci est r\u00e9alis\u00e9, entre autres, avec l’extraction CO\u00b2. Ce proc\u00e9d\u00e9 promet l’extraction d’une huile pure \u00e0 haute teneur en CBD<\/strong>. \u00c0 cette fin, on utilise g\u00e9n\u00e9ralement du chanvre commercial<\/a> ayant la plus faible teneur en THC possible.<\/p>\n

L’extraction du CBD est un processus complexe<\/strong> qui est g\u00e9n\u00e9ralement r\u00e9alis\u00e9 avec du dioxyde de carbone. Alternativement, l’alcool peut \u00e9galement \u00eatre utilis\u00e9. Cette variante est consid\u00e9r\u00e9e comme moins ch\u00e8re et moins complexe que l’extraction au CO\u00b2 du CBD<\/strong>.<\/p>\n

Pendant l’extraction au CO\u00b2, l’extrait de CBD est s\u00e9par\u00e9 du reste de la mati\u00e8re v\u00e9g\u00e9tale<\/strong>. La premi\u00e8re \u00e9tape consiste \u00e0 chauffer la plante de chanvre. De cette fa\u00e7on, le pr\u00e9curseur inactif CBDA peut \u00eatre converti en CBD actif. Ce processus est appel\u00e9 d\u00e9carboxylation<\/strong>.<\/p>\n

On distingue l’extraction au CO\u00b2 supercritique et l’extraction au CO\u00b2 sous-critique. Le terme \u00ab\u00a0critique\u00a0\u00bb fait r\u00e9f\u00e9rence \u00e0 l’\u00e9tat chimique du dioxyde de carbone<\/strong>. Dans l’extraction supercritique du CO\u00b2, cet \u00e9tat se situe entre liquide et gazeux. Il est d\u00e9clench\u00e9 par l’augmentation de la pression et l’abaissement de la temp\u00e9rature du CO\u00b2.<\/p>\n

Lorsque le dioxyde de carbone atteint l’\u00e9tat critique, il agit comme un solvant. Dans la deuxi\u00e8me \u00e9tape du processus, le mat\u00e9riel v\u00e9g\u00e9tal est donc satur\u00e9 de CO\u00b2 afin que le CBD se dissolve du chanvre utile<\/strong>. La temp\u00e9rature et la pression doivent alors \u00eatre \u00e0 nouveau ajust\u00e9es. Si la temp\u00e9rature augmente et que la pression diminue, le dioxyde de carbone revient \u00e0 l’\u00e9tat gazeux. De cette fa\u00e7on, il peut \u00eatre s\u00e9par\u00e9 de l’extrait de CBD dissous. Ce qui reste est de l’huile de CBD<\/a> hautement concentr\u00e9e.<\/p>\n

L’extraction au CO\u00b2 subcritique du CBD se d\u00e9roule de mani\u00e8re similaire. Toutefois, \u00e0 une pression plus faible, c’est pourquoi cette proc\u00e9dure est consid\u00e9r\u00e9e comme particuli\u00e8rement douce<\/strong>. Dans ce cas, plusieurs processus d’extraction sont n\u00e9cessaires pour obtenir l’huile de CBD.<\/p>\n

Parmi les avantages de l’extraction naturelle de l’extrait de CBD figure avant tout l’effet plus fort obtenu au final<\/strong>. L’extrait se caract\u00e9rise par une concentration particuli\u00e8rement \u00e9lev\u00e9e de cannabino\u00efdes<\/strong>, dont vous b\u00e9n\u00e9ficiez naturellement en tant qu’utilisateur. Les isolats de cannabidiol<\/a>, qui sont produits synth\u00e9tiquement, ne peuvent g\u00e9n\u00e9ralement pas suivre.<\/p>\n

Cependant, l’extraction de CBD au CO\u00b2 conna\u00eet aussi ses inconv\u00e9nients. Au premier plan se trouve clairement la proc\u00e9dure complexe. L’extraction de l’huile de CBD<\/strong> ne r\u00e9ussit que si la temp\u00e9rature et la pression sont correctement s\u00e9lectionn\u00e9es. En outre, de pr\u00e9cieux ingr\u00e9dients de la plante<\/strong> sont perdus au cours du processus. Car le CBD n’est pas le seul \u00e0 \u00eatre soluble dans le dioxyde de carbone. Les terp\u00e8nes<\/a> et les flavono\u00efdes porteurs d’ar\u00f4mes quittent \u00e9galement la plante.<\/p>\n
