Question about alcohol extraction on myc.
    #22288703 - 09/25/15 02:38 PM (8 years, 4 months ago)

After years of perusing the forums I've finally made the effort to create an account. I would love to tell you all that this is because I would like to contribute back to the community. Alas, I'm not that an experienced grower and thus haven't made any new discoveries that would add anything to this fun and insightful depository of useful information!

The real reasoning behind my far from alacritous account acquisition is a burning question on which I haven't found any information at all.

Namely, is it safe to do an alcohol extraction on the most commonly used substrates? I'm especially wondering about straw substrate (with some BR(F)), that is currently colonized and just now freshly cased in verm.

Any insights would be grand!

And once again, my apologies if posting my inquiry here is misplaced, inconsiderate, half-witted and ludicrous.

Mycelium won't have much actives. Not until they've flushed out a bunch. But at that point you have other things in it. Bacteria, and possibly other contaminants you can't see. Extraction with alcohol could potentially extract harmful mycotoxins, or other secretions/metabolites of bad molds. Thus it's not safe imo to consume. Alcohol extractions are great on fruits. Substrates are great for the garden

Why wouldn't you just finish the grow? I could see someone *attempting* to extract from like maybe grain spawn, but if you already have colonized substrate that's been cased I have no idea why you wouldn't just wait a week?

I definitely wouldn't want to have any mycotoxins for diner. Thank you Mad Season!

And the idea was to first have it flush a couple of times and only then do the extraction on the myc. mushpunx. Thanks for weighing in nonetheless!

After reading a bunch about ethanol extraction, here is what I believe might be a good way to go about it. The final goal being to keep all the actives dissolved in the final product, reduced to the equivalent of 1g dried to 1ml.

Anyway, what do you think about the following:

1. Powder dry shrooms.

2. Add Ethanol (I've got 96% (192 proof)) combined with ascorbic acid (to counter oxidation) in the equivalent of 4.40325 g/l. (as posted by udok (in this thread: http://www.shroomery.org/forums/showflat.php/Number/5489469/fpart/all/vc/1): "Molecular mass of ascorbic acid = 176.13g/mol. *25mM = 176.13 * 0.001 * 25 = 4.40325 g/l")

Additionally I'm considering to add citric acid and/or vinegar (to lower ph to counter dephosphorylation of psilocybin). But in what ratio?! Has anyone got any ideas?

3. Mix 1x the volume of powdered shrooms with 2x volume of solvent.

4. Let mixture stand and shake often for at least two hours, three to be sure.

5. Filter

6. Repeat extraction on remaining solids using less solvent, about 1.2x the volume of solids.

7. Filter.

8. Optionally extract/rinse again. Might be needed, see shirley knott's extraction: http://www.shroomery.org/forums/showflat.php/Number/6194866/fpart/3/vc/1#6194866

9. Reduce the liquid to an equivalent of 1g of dried shrooms to 1ml using "ice pot still" method. I'm hoping that heating the solution won't be necessary and some ethanol can be recaptured. Also hoping the remaining will be liquid and not viscous.

Optional
I want one of those soxhlet extractors. I know, it's not quite necessary, but they just look fantastic! I might improvise one and use that instead of the method described above.

Any thoughts about all of the above? Have I missed something and or do you see room for improvement?

Your help is very much appreciated!

Psilocin is polar, and more readily soluble in water. Alcohol will reduce oxidation, and make it storeable. I find 70% alcohol (140ish proof) is the best for extraction, as well as storage/evaporation.

As for pH, I don't think it matters much. A too low or too high pH will cause more oxidation. That's why you need a happy medium. I aim for 6-7.

Ascorbic acid (vitamin C) is an antioxidant, you are correct. But it is also an acid. You dont want to add too much, lower the pH, and increase oxidation. Again with vitamin c, I like to add enough until I get to a pH of 6-7. Because of this, I definitely don't use any other kind of acid.

As for evaporation, put it in a flat container, and point a fan at it so the surface has a slight ripple. It'll evaporate fully in a day or 2, so keep an eye on it. Make sure you get it to your desired dosage.

I've evaporated it all the way. It turns into a brown goo. This too is fuckin amazing. A small piece the size of a rocket feels like 7-14 grams lol
