I've been trying to use a Pressure Cooker(PC) to get the actives into solution from B.caapi vine.
First using "McKenna Red" young vine. Yield was around .04%....real shitty. I figured it was really weak vine.
Second attempt using "Trueno" black vine (5-7x thicker than the yound red vine) and I also did an additional cycle with the PC (15psi for 15min) for a total of 4 cycles. I haven't finished the extraction, but it already looks weak. If I don't see some substantial precipitate soon, I'm just going to chuck it.
So I'm wondering why? The PC always works great for other stubborn alks, ie. cactus and syrian rue.
All I can think is the extraction is more dependent on duration of exposure to the heated acidic water, than the temperature.
OR, The PC is destroying the actives, but I doubt it.
Gibran's tek gently boiled for 30mins and 4 cycles. 2hrs in solution
I PC'd for 15min at 15psi for 4 cycles. 1hr20min because the PC had to heat up during each cycle for 5min.
Traditionally for Aya 3 cycles for 3 hrs each. 9hrs in solution
Any ideas???
