    You can make thimbles by rolling up a sheet of paper in a cylinder and stapling the bottom shut. It's a bit less hassle than the cotton and helps the siphon work better when using fine powders. Another tip I use is filling the boiling flask by pouring the solvent over the soxhlet, saves time on a couple cycles Keep up the good content!

    Depending on speed of boiling, three cycles of extraction may not be very much. You may want to try long soaking time (slow boiiling) and/or more cycles.

      I was going to say the same thing. I've done this exact extraction and my group decided to let it cycle for 2 hours and the solvent eventually would come through clear, I think we got like 70% of the piperine out.

      Thank you so much! I definitely make these through the lens of accessibility, I feel too long and you lose people, too much detail and you lose people, but overly dumbed-down and then it feels too much like pop-science. Glad you think I've got a good balance going on!

    piperine degrades over time and obviously faster in pre ground peppercorns. so ideally you should use whole peppercorns and grate them shortly before use. that would certaintly increase yield. also preground peppercorns are usually lower grade stuff since you can't tell by looking at them.
    This is true of most spices, the pre ground or pre extracted version is usually low[er] grade stuff that can't be sold whole

    • @integral_chemistry

      Yeah I definitely want to try again with an equal mass of some very fresh peppercorns, think it would be a fun little proof that the pre-ground stuff is trash.

    2:50 Another downside of this process is that the extracted matter in the round bottom flask is exposed to the boiling temperatur of the solvent for a longer period of time (in the case of iso-Propanol 82 °C). But this cannot be prevented, except you choose another solvent with a lower boiling point (if there is one).

    • @integral_chemistry

      I was actually thinking of doing this again with diethyl ether. Boiling point is 35°C and it forms a seperate layer in solution so I could do an actual washing step with the Extract

  • @Gman193
    @Gman193 Год назад +3

    To improve yield, you could soak the pepper in you solvent before starting the extraction. This could even be done in the soxhlet. Just put your pepper in the soxhlet, cover with isopropanol ( just not enough to trigger the siphon) and leave it like that for a couple of days. Also you can crash out the piperine with you solvent warm and then let it cool down, that way you get bigger crystals and less wil pass through your filter. Other then that, nice video.

  • @zuthalsoraniz6764
    @zuthalsoraniz6764 Год назад +4

    Maybe you could try extracting allicin from crushed garlic? Haven't seen anyone do that one before on youtube, and it should be fairly well soluble in ethanol. Though it has a fairly short half-life at least in aqueous solution, which might make getting a decent yield quite tricky.

    You should try chile peppers for capsaicin others have done it but they stop at the oil not the pure crystals. I believe you already have the needed solvents for the final wash

    • @integral_chemistry
      @integral_chemistry  Год назад +1

      I've considered that honestly. I figure the oils could be separated out with a glycerin-ether extraction, the issue is separating the carotenoids from the capsaicinoids as they have such similar solubilities..

    • @aSCrouton
      @aSCrouton Год назад

      hmm yeah. the carotenoids dont have a phenol group like capsaicin though right? could you exploit the solubilities through protonation and deprotonation then? maybe the carotenoid species are too diverse for that to work. idk. @@integral_chemistry

    From my experience, using a thimble is counter productive since you can use less black pepper overall, I personally like to use cotton ball or "tea-bag" filter to contain the material for extraction, this not only increase the product, it is also much easier to clean than the timble, especially for extraction like capsaicinoid which the chilli stinks the fritted glass pretty heavily.

    • @integral_chemistry
      @integral_chemistry  Год назад +2

      I honestly agree with you (tbh I mentioned the thimble to avoid people trying to call me out for not using one lol). But yeah the thimble just feels too limiting. It sucks for all the reasons you mentioned and I'm not sure if my thimble is just the wrong size but I nearly had some overflow of particulate when I last tried to use it.

    Preground black pepper, definetly has less taste and fragrance than freshly ground black pepper. I'm guessing it's due to oxidation or breakdown of the piperine in the pepper?
    I would not be surprised if you would get a higher yild from freshly ground black pepper, also ground to a finer powder instead of the coarse material you used.

    Anyone know if the NaOH/IPA step would work with capsaicin extracted in the same way? I did this extraction with c. Reaper peppers and have like 500ml of red oil but i want to refine and crystalize the capsaicin if possible. btw i know its dangerous and no plan to eat it, its just a fun project

    • @integral_chemistry
      @integral_chemistry  Год назад +1

      I actually am working on that exact project rn and what worked for me was actually dissolving the oil in glycerin and then extracting out the capsaicin with diethyl ether. Capcasin isn't soluble in glycerin but all the fats and oils are, so all the capcasin gets extracted into the ether which forms a nice seperate layer. Only issue is the red carotenoids also get extracted with the capsaicin and I've got no idea how to seperate the two :(

    I buy black peppercorns in bulk from the grocery store. In the last couple years, they have been completely flavorless. I suspect the oils are being extracted from them, and the spent husks are being sold. It wouldn't surprise me if pre-ground pepper is being treated the same way. Twice the money for the same product. There's a conspiracy to _de-caffeinate_ our pepper!
