Newbie spice extract question... to defat or not to defat?
Posted 04 April 2012 - 01:55 PM
I (think) i have decided on Marsofolds tek, but tempted by the Lazymans. Both seem easy enough for my chemistry skill level, or lack of.
The question i have though is why does one tek soak the mhrb in vinegar first but the other tek goes straight into the naoh. Is this the defat process? And why is it not so important?
Thanks in advance, i appreciate your help!! :D

Thanks for your reply. Think this is starting to make more sense to me now, i now realize the difference between stb and a-b... So in the stb tek the DMT is precipitated out leaving the salt behind? Is this precipitation you mention the last procedure? ...
I notice that Marsofolds a-b tek requires freeze precipitation, but the other stb tek the naphtha/dmt solution is completely evaporated down. Do you know if this is required because of the different a-b / stb procedure, or does it not matter that much?
Sorry for a the questions, the teks are really clear in what to do, im just curious on what is happening i guess.

Freeze precipitation can be done instead of evaporation and vice-versa.
STB is just converting the alkaloids in the plant into freebase form and dissolving them in a nonpolar solvent.
A/B doesn't necessarily require the defat step, but I think without the defat A/B is pointless.
My opinion has always been that one should get the basic concept before preforming an extraction so they aren't restricted to a "tek."

What im thinking is im not sure if a defat will save me a wash at the end, as im not fancying doing a wash. (just incase i loose too much yeild, im starting with 100g of MHRB) However im wondering that if i do go with a defat with a-b method, maybe the yeild wont be as good as doing stb.
I really liked the watcha's tek, but it means sourcing more chems for the clean.
Thanks for your input!! ;)
