(EN) IMPRINTED POLYMERS AND METHODS FOR THEIR USE
(FR) POLYMÈRES À EMPREINTE ET PROCÉDÉS POUR LEUR UTILISATION
Abstract
(EN) This disclosure relates to an imprinted polymer and/or an imprinted polymer bead for producing an enriched cannabinoid extract from a crude cannabis extract. This disclosure further or alternatively relates to a method of making an imprinted polymer for producing an enriched cannabinoid extract from a crude cannabis extract and/or a method of producing an enriched cannabinoid extract from a crude cannabis extract and/or a method of reducing heavy metal content in an enriched cannabinoid extract when compared to a crude cannabis extract and/or a method of reducing at least one pesticide residue in an enriched cannabinoid extract when compared to a crude cannabis extract and/or a method of reducing lipid extraction steps when producing an enriched cannabinoid extract from a crude cannabis extract and/or method of producing an enriched cannabinoid extract from a crude non-winterized cannabis extract. This disclosure further relates to an enriched cannabinoid extract. More particularly, this disclosure relates to use of molecularly imprinted polymers to produce enriched cannabinoid extracts from crude cannabis extract.
(FR) La présente invention concerne un polymère à empreinte et/ou un cordon de polymère à empreinte pour produire un extrait de cannabinoïde enrichi à partir d'un extrait de cannabis brut. La présente invention concerne en outre un procédé de fabrication d'un polymère imprimé pour produire un extrait de cannabinoïde enrichi à partir d'un extrait de cannabis brut et/ou un procédé de production d'un extrait de cannabinoïde enrichi à partir d'un extrait de cannabis brut et/ou un procédé de réduction de la teneur en métaux lourds dans un extrait de cannabinoïde enrichi par comparaison avec un extrait de cannabis brut et/ou un procédé de réduction d'au moins un résidu de pesticide dans un extrait de cannabinoïde enrichi par comparaison avec un extrait de cannabis brut et/ou un procédé de réduction des étapes d'extraction de lipides lors de la production d'un extrait de cannabinoïde enrichi à partir d'un extrait de cannabis brut et/ou un procédé de production d'un extrait de cannabinoïde enrichi à partir d'un extrait brut de cannabis non enroulable. La présente invention concerne en outre un extrait de cannabinoïde enrichi. Plus particulièrement, l'invention concerne l'utilisation de polymères à empreinte moléculaire pour produire des extraits de cannabinoïdes enrichis à partir d'extrait de cannabis brut.
