In this video, I am decaffeinating green coffee beans by the direct organic solvent method.
Unfortunately, I couldn't find a patent for this particular process and had to rely on my intuition and the bits and pieces I could find on google search.
In any case, decaffeination process was successful, though I couldn't determine the amount of caffeine extracted by weight.

brilliant video as usual , amazing music:)
I don't think you should use CaCl2 as the drying agent because CaCl2 reacts with amines.
better to use NaOH instead

Hi, thank you for your pleasant feedback.
To be honest I didn't realise that calcium chloride reacts with amines when submerged in the solvent, thanks for pointing this out.
I will do a more detailed research on drying agents, really I think I should have used molecular sieves instead.
