Ci\u00f2 si ottiene in vari modi, uno dei quali \u00e8 l\u2019estrazione con CO\u00b2. Il processo garantisce l\u2019estrazione di un <strong>olio puro ad alto contenuto di CBD<\/strong>. Per questo scopo viene <a href=\"https:\/\/www.tomhemps.com\/it\/cbdictionary\/canapa\/\">utilizzata canapa<\/a> commerciale con il minimo contenuto possibile di THC.<\/p>\n<p>L\u2019estrazione del CBD \u00e8 un <strong>processo complesso<\/strong> che viene solitamente eseguito con diossido di carbonio. In alternativa si pu\u00f2 utilizzare anche l\u2019alcool. Questa variante viene considerata pi\u00f9 economica e meno complicata dell\u2019<strong>estrazione di CBD con CO\u00b2<\/strong>.<\/p>\n<p>Durante l\u2019estrazione con CO\u00b2, l\u2019estratto di CBD viene <strong>separato dal resto del materiale vegetale<\/strong>. Il primo passo \u00e8 quello di riscaldare la pianta di canapa. In questo modo, il precursore inattivo CBDA viene convertito in CBD attivo. Questo processo viene detto <strong>decarbossilazione<\/strong>.<\/p>\n<p>Viene fatta una distinzione tra l&#8217;estrazione con CO\u00b2 supercritico e l&#8217;estrazione con CO\u00b2 subcritico. Il termine \u201ecritico\u201c si riferisce allo <strong>stato chimico del diossido di carbonio<\/strong>. Nell\u2019estrazione con CO\u00b2 supercritico si tratta di uno stato fra il liquido e il gassoso. Questo si ottiene aumentando la pressione e diminuendo la temperatura del CO\u00b2.<\/p>\n<p>Quando il diossido di carbonio raggiunge uno stato critico, agisce come un solvente. Nel secondo passo del processo, il materiale vegetale viene quindi saturato con CO\u00b2 di modo che il <strong>CBD si dissolva e fuoriesca dalla canapa<\/strong>. Temperatura e pressione devono quindi essere riaggiustate. Se la temperatura aumenta e la pressione diminuisce, il diossido di carbonio torna allo stato gassoso e pu\u00f2 essere cosi separato dall\u2019estratto dissolto di CBD. Ci\u00f2 che rimane \u00e8 un <a href=\"https:\/\/www.tomhemps.com\/it\/cbdictionary\/olio-di-cbd\/\">olio di CBD<\/a> altamente concentrato.<\/p>\n<p>L\u2019estrazione di CBD con CO\u00b2 subcritico avviene in modo analogo, ma ad una minore pressione. Perci\u00f2 questa procedura \u00e8 <strong>considerata particolarmente delicata<\/strong>. In questo caso sono necessari svariati processi di estrazione per ottenere l\u2019olio di CBD.<\/p>\n<p>Fra i vantaggi dell\u2019estrazione naturale del CBD, il pi\u00f9 importante \u00e8 una <strong>maggiore efficacia <\/strong>del prodotto finale. L\u2019estratto \u00e8 caratterizzato da una <strong>concentrazione particolarmente alta di cannabinoidi<\/strong>, da cui il consumatore trae naturalmente vantaggio. Gli <a href=\"https:\/\/www.tomhemps.com\/it\/cbdictionary\/isolato-di-cbd\/\">isolati di cannabidiolo<\/a>, che vengono prodotti in modo sintetico, non sono solitamente paragonabili.<\/p>\n<p>Tuttavia, l\u2019estrazione di CBD con CO\u00b2 ha anche degli svantaggi. In primo luogo, chiaramente, la procedura complessa. L\u2019<strong>estrazione dell\u2019olio di CBD<\/strong> ha successo solo se temperatura e pressione vengono regolate correttamente. Inoltre, <strong>preziosi elementi della pianta vanno perduti<\/strong> durante il processo. Perch\u00e9 non solo il CBD si scioglie nel diossido di carbonio. Anche i <a href=\"https:\/\/www.tomhemps.com\/it\/cbdictionary\/terpeni\/\">terpeni<\/a> aromatici e i flavonoidi si separano dalla pianta.<\/p>\n<p><small>Photo: SA Production \/ <a
