.....I have been studying extraction techniques a little bit recently and watching your thread....very good stuff BTW.....i was just browsing ebay and I found Everclear at £69.99 inc postage per litre lol.....Im not paying that haha....is food grade anything ok to use?.....such as food grade isopropyl alcohol?....thanks in advance
Hey there! I'm no expert.
@Mañ'O'Green has far more experience, check his thread on extractions.
I'm using food grade 95% ethanol.
I'm tempted to use isopropyl, as I'm confident I can vaporize off all the isopropyl and leave it clean.
But... I need to research it a bit more to be sure.
I don't think there is food grade isopropyl, is there? It's a toxin to humans.
Ethanol is, too, but somehow we have a culture of consuming the stuff... (well, other people, not me!)
I think do go for something food grade, i.e. something that humans can put in their bodies in small amounts that aren't toxic.
I'm finding that doing these ethanol cook offs far easier than straight oil (or butter).
The oil and butter methods take hours to cook. Though, the result of my coconut oil was very good.
I'm finding that with two washes, then two quick strains, rice cooker as double boiler, can do whole cook in maybe 90 minutes.
