You could extract without drying and get the same output. There's a research paper on it using 100 proof ethanol (4ml per gram fresh), 90C temp water bath over 2 hours. Recovery was over 85% of available capsaicin. With a sox, recovery would be even higher but they didn't use it due to needing to industrialize it. They also found anything over 50% alcohol (100 proof) didn't increase the recovery.
@@SteveSerrano65 It's an older paper so maybe others have built upon their work but the title is: "Stage extraction of capsaicinoids and red pigments from fresh red pepper (Capsicum) fruits with ethanol as solvent" Should be available free to read if you google it. If I post a link, the algo ban hammer will punt me off and restrict my acct again. I have read a few later papers that compare ethanol with other non-editable solvents like hexane, acetone, methanol. Considering the safety factor, ethanol wins in everything except CO2 extraction (which is all but impossible for us home chemists).
That is an excellent paper! So as not to repeat everything they did, but taking advantage of what they learned, I'm going to chop a kilo of serrano peppers in a food processor and soak the chopped veggies in warm 70% IPA for two days. The pressed filtrate will then be evaporated to dryness (or goo) at a mere 40 C (we have a dry climate). I won't bother to remove the last molecule of isopropanol because it's not that toxic. If it were, I'd be dead already.
You can do the same thing without all the bells and whistles. Dice or grind the peppers. And dump them in the ever clear. Sealed in a mason jar and set in the sun for a day or 2. The Alcohol will extract the capsaicin. Strain out the pepper bits and leave the jar open to allow the alcohol to evaporat. It may not be as fast or pure. But it's much less complicated, and it's damn hot. And a lot safer.
Ethanol does not cause blindness. It is true that enough ethanol can kill you but it does not cause blindness. Blindness is caused by methanol which is toxic and damages the optic nerves (and other organs). A measure of toxicity of a substance is the LD50 value (the median lethal dose ) often measured in rats rather than humans, for obvious reasons. The LD50 (rats) of Ethanol is 7060 mg/kg and the LD50 (human) of methanol is 810 mg/kg. One of the antidotes for methanol poisoning is ethanol !
I can only get everclear 151 where I live. That works. I extracted it more quickly by putting covered jars in the sous vide at 160F so the alcohol wouldn't boil off, washing hourly until the fluid layer got lighter in color, then dehydrating in a dehydrator. The brown, tarry resin is not soluble in oil. I added some alcohol back to it to suspend it and will be using it by the drop.
Great video - very well done! As for re-using the ethanol - you’ll probably find it has an intense pepper flavour, but without the heat, which doesn’t pass through the distillation process. I’ve done the reverse, distilling Carolina Reaper peppers to extract the flavour into alcohol without the burn! I would be cautious re-using that ethanol without flavour testing it first, as you would need some different kit to really get it back to neutral.
Awesome! Question for soxhlet and condenser which I have both I have a fractional condenser but the problem is from bottom tip of my condenser and to soxhlet size to big. Meaning the soxhlet top is wider but my condenser tip is smaller so is it possible to used and cut a wine bottle using the top half as adapter as substitute for now?
Depends on what you mean by safe. Alcohol of any concentration will boil off as pure ethanol (distillation). As with any solvent, never ever do this without an exhaust vent/hood or in a closed space as vapors can poison you or explode.
Yes, with precautions - once ethanol/alcohol starts to boil and creat vapour, the vapour is going to be highly flammable and concentrated regardless of the original abv of the ethanol source. Put another way, ethanol vapour coming off a 30% base will be the same as ethanol coming off a 48% base. That said, the % of the base does impact quite how fast it boils, so most distilleries don’t use a base ethanol mix of much over 45% just to keep the boil rate more controlled.
You're correct. You CAN get 100% ethanol, just not from distillation. You would need a secondary drying, like those little sivvs or something that soak up molecular water.

That way is not so fun! 😎

Probably lost a good amount of ethanol in the cotton

As long as the seal is tight you should be fine to do that.
@@Chefandbee thank you. One more question. Do think teflon fast seal tape can be as seal!
I think you should be okay using Teflon I know it’s capable of withstanding high temps and this extraction doesn’t involve a super high temperature
@@Chefandbee thank you once again I appreciate it
Could I use this concentrate to make a cream?
You could yes
You would have to try this with your chosen carrier. The concentrated goo is not soluble in olive oil.
Hi Is it safe to boil alcohol over 40%? Thanks

@@BrazilSaint I guess my 3 sentence explanation wasn't wordy enough? 😋
@@cenobytecode yeah, needed at least 5 or 6 sentences 🤣
Thank you :) @@BrazilSaint
Hilarious, no need for most of that .
When you mention that you can get 100% alcohol, I thought that you couldn't because of the azeotrope?,can you?

Just do it dude !
Way too much bla bla bla.
They have to make it longer to make any money.
