A fim de produzir produtos de CBD<\/a> de alta qualidade, o extrato de CBD<\/a> tem primeiro de ser extra\u00eddo da planta de can\u00e1bis. Isto pode ser feito, entre outras m\u00e9todos, com extra\u00e7\u00e3o de CO\u00b2. O processo promete a extra\u00e7\u00e3o de \u00f3leo puro com um elevado conte\u00fado de CBD<\/strong>. Para este fim, \u00e9 normalmente utilizada can\u00e1bis comercial<\/a> com o menor teor poss\u00edvel de THC.<\/p>\n

A extra\u00e7\u00e3o de CBD \u00e9 um processo complexo<\/strong> que \u00e9 normalmente realizado com di\u00f3xido de carbono. Alternativamente, o \u00e1lcool tamb\u00e9m pode ser utilizado. Esta variante \u00e9 considerada mais barata e menos complexa do que a extra\u00e7\u00e3o de CO\u00b2 de CBD<\/strong>.<\/p>\n

Durante a extra\u00e7\u00e3o de CO\u00b2, o extrato de CBD \u00e9 separado do resto do material vegetal<\/strong>. O primeiro passo \u00e9 aquecer a planta da can\u00e1bis. Desta forma, o precursor inativo CBDA pode ser convertido em CBD ativo. Este processo \u00e9 chamado descarboxila\u00e7\u00e3o<\/strong>.<\/p>\n

\u00c9 feita uma distin\u00e7\u00e3o entre a extra\u00e7\u00e3o supercr\u00edtica de CO\u00b2 e a extra\u00e7\u00e3o subcr\u00edtica de CO\u00b2. O termo “cr\u00edtico” refere-se ao estado qu\u00edmico do di\u00f3xido de carbono<\/strong>. Na extra\u00e7\u00e3o supercr\u00edtica de CO\u00b2, o estado qu\u00edmico encontra-se entre o l\u00edquido e o gasoso. \u00c9 desencadeada pelo aumento da press\u00e3o e pela redu\u00e7\u00e3o da temperatura do CO\u00b2.<\/p>\n

Quando o di\u00f3xido de carbono atinge um estado cr\u00edtico, atua como um solvente. Na segunda etapa do processo, o material vegetal \u00e9 saturado com CO\u00b2 de modo que o CBD se dissolva da can\u00e1bis<\/strong>. Depois a temperatura e a press\u00e3o t\u00eam de ser novamente ajustadas. Se a temperatura aumenta e a press\u00e3o diminui, o di\u00f3xido de carbono regressa ao estado gasoso. Desta forma, pode ser separado do extrato dissolvido de CBD. O que resta \u00e9 petr\u00f3leo altamente concentrado de CBD.<\/p>\n

A extra\u00e7\u00e3o subcr\u00edtica de CO\u00b2 de CBD procede de forma semelhante. No entanto, a uma press\u00e3o mais baixa, e \u00e9 por isso que este procedimento \u00e9 considerado particularmente suave<\/strong>. Neste caso, por\u00e9m, s\u00e3o necess\u00e1rios v\u00e1rios processos de extra\u00e7\u00e3o para obter o \u00f3leo de CBD<\/a>.<\/p>\n

As vantagens da extra\u00e7\u00e3o natural do extrato de CBD incluem em primeiro lugar e acima de tudo o efeito mais forte conseguido no final. O extrato \u00e9 caracterizado por uma concentra\u00e7\u00e3o de canabin\u00f3ides<\/strong> particularmente elevada, da qual o utilizador beneficia naturalmente. Os Cannabidiol isolados<\/a>, que s\u00e3o produzidos sinteticamente, normalmente n\u00e3o conseguem acompanhar.<\/p>\n

No entanto, a extra\u00e7\u00e3o de CO\u00b2 de CBD tamb\u00e9m tem as suas desvantagens. Em primeiro plano est\u00e1 claramente o procedimento complexo. A extra\u00e7\u00e3o do \u00f3leo de CBD<\/strong> s\u00f3 \u00e9 bem-sucedida se a temperatura e a press\u00e3o forem corretamente selecionadas. Al\u00e9m disso, os ingredientes valiosos da planta<\/strong> s\u00e3o perdidos durante o processo. Porque n\u00e3o s\u00f3 o CBD \u00e9 sol\u00favel em di\u00f3xido de carbono. Perdem-se tamb\u00e9m os terpenos<\/a> arom\u00e1ticos e os flavonoides.<\/p>\n
