Abstract: The invention relates to methods for preparing a concentrated cannabinoid product optionally also containing an array of terpenes, flavonoids, and other phytoconstituents from a cannabinoid-containing extract feed. The cannabinoid-containing extract feed is contacted with an adsorbent to produce a pre-treated extract which is then subjected to one or more filtration steps, and recovering the concentrated cannabinoid product utilizing an extractant or an evaporator.

Abstract: The present disclosure relates to an electrolysis apparatus that includes an anode electrically connectable to a direct current electrical source. The apparatus also includes a cathode comprising a proximal segment and a distal segment. The proximal segment is electrically connectable to the direct current electrical source. Further, the apparatus includes a hydrogen collector receptacle that limits generation and collection of hydrogen at the cathode to a specified amount. The hydrogen collector receptacle encompasses a portion of the cathode. Also, the apparatus includes a delivery device that receives hydrogen from and is connected to the hydrogen collector receptacle. According to one embodiment, the hydrogen gas generated in the electrolysis apparatus and collected in the collector receptacle is less than about 4.5% of a user's breath.
