Oil Extraction: Bringing out the 'Head' properties

[kl.metacog]

Well, I was going to make a complete write up, but it's difficult to think right now.  All I can say is wow.  I sampled 3 teaspoons of the finished product and I feel like I just smoked two hits of really good cannabis.
I promise I'll get pics and the process up later. In the meantime, I'm gunna jam on some tuneage (smiley: smokin)

I'm excited for this! Do you think it was worth using the root for this?

Krunkedout, this is forever going to change how I ingest kava.

Fill a Buddha in? Ive been away for a while.

I see from the chat that you used 1/2 cup peanut oil and 1/2 cup vegetable oil and 1/2 cup boroguru baked in an oven at 275 for 1 hour.  I'm assuming you then cooled it and strained it.  I suspect another option which would work well would be a double boiler as it would also keep the oil from getting too hot.  Pretty great stuff, I may have to try it tonight.

I got my boroguru in the mail today, and excited to  try my own hand at making an oil extract got down to work.  
Initial Materials:  Peanut oil, vegetable oil, BKH Boroguru kava, measuring cups, food thermometer.

My first idea was to use a 1:1 ratio of kava to oil, but the consistency wasn't quite right so I added another half cup.  The proportions I used were 1/2 cup peanut oil, 1/2 vegetable oil, and 1/2  root.  I would have used 100% peanut oil, but the shit's expensive.  I'd imagine any oil with a suitable fat content will do. 

The ingredients were thoroughly mixed and placed in the oven at 275 degrees for one hour.  Every fifteen minutes it was brought out to be re-stirred.  After one hour transpired, the mix  was pulled out and the temperature was taken at 130 degrees F.  This was a surprising reading as I had thought it would be closer to 200 degrees, but the repeated removal from the oven could have had a role in influencing the temp.

This is the unfiltered mixture straight from the oven.  As you can see, it has all settled to the bottom.

A spoonful off the top.

Since there was a pretty substantial clear oil layer I decided to pour it off into another container (the mixing bowl).  The pan on the leftis the remaining kava and oil.  With what was leftover in the pan, I added water and stirred the kava (it formed into clumps) and poured offthe water into another pan.  The remaining kava clumps were then combined with a half cup of water and filtered through a T-shirt.  This wasthen added to the pan with water/oil.

This is the product of the T-shirt strain.
The water pan is in the fridge currently.  I am hoping that after some time an oil layer will form on top of the water.  With this I hope to siphon off to add to the extract supply.

In future experiments, I plan on changing the oven temperature and seeing how that effects the potency/kavalactone content.
The Extract:
This stuff is really potent, so be careful.  As my original post stated, the buzz had a very distinct cannabis character to it; lots of spacing out, increased sensitivity to music, and similar body sensations.

I'm curious about your oven / thermometer.  Something must not be right.  I set my oven to 250, and placed the oil mixture in there in a glass pan just as you did, but after 15 min, it was already at 170F.  So i dropped the temperature of the oven down to 150, and I'll keep it there for the rest of the time.

 

[kl.metacog]

Well, my oven is pretty old and the thermometer is cheap. Its possible that both of those could of played a role in the low temperature. What kind of oil are you using?

I will recount my experiment here as well.  So based on what metacog said, I took a cup of canola oil (it's all I had around) and 1/2 cup of fu'u and blended them together for a minute, then poured into a glass pan.  I pre-heated my oven to 250 and popped it in.  After 15 min I pulled it out to stir, and also took the temperature using my thermapen (very fast and accurate) and it was already around 170.  So I dropped the temp of the oven to 150 and let the door sit open for a couple of minutes and then put it back in.  After another 15 min, I stirred, and took the temperature again.  It was around 160.  Back in the oven, 2 more 15 min periods.  At that point there was basically dark brown sludge with some clear oil on top.  I took it and poured off some of the clear oil and some of the sludge into a coffee filter and strained out some ever so slightly cloudy oil, probably a 1/4 cup to 1/2 cup.  I sampled the oil and found it to not taste very kava like, and did not really numb my tongue.  I drank 4 tsp, and felt no noticeable effect.  I then took all of the unstrained sludge and what was still in the coffee filter and strained it using a t-shirt.  This resulted in a much darker oil.  I drank a tbsp of it, which tasted a little bitter, and felt a slight tongue numbing and throat burning, but little to no effects.  I was unwilling to drink any more oil at that point, so I stopped.


So I had a less desireable result than metacog.  The main differences in our prep as I see them are:


1. I used fu'u not boroguru

2. I cooked at what I believe was probably a much lower temperature of 150 rather than > 200.

3. I strained initially using a coffee filter and then samped that.  Metacog sampled the separated oil directly at first.


And for those worried about ingesting oil and it causing bowel issues, I did not experience any problems.  I ingested about 3.5 tbsp of canola oil in my testing.

Allright, I tried a method just now using this oven oil water technique all you guys are doing, this time was experimental though so i just eyeballed everything to just see if it would work at all, and used strictly coconut oil and water, and boroguru, the really fine grind, will do measurements next time. this technique is perfect for this hard to deal with fine grind since its so hard to mess with, and TnW gives skin problems.
So after the hour was up, more like hour and a half, I poured warm concoction into a cup unstrained, to give the mixture more depth, to seperate the water and oil more clearly, and just threw it in the freezer for about 20 mins, and wa la! pulled it out with a thick bright yellow solid mass resting on top knarley sludgy brown crap. no straining necessary, the oil just solidifies with the lactones up top, just sublingualed a bit, and it was much stronger than expected, so this is very exciting, bye far the cleanest most efficient kava prep ive dealt with, no squeezing straining, and splatters of liquid all over the kitchen to piss your g/f off, lol. so thats my 2 cents.

 

[kl.metacog]

Awesome! Yeah coconut oil seems very convenient with it's ease of solidification. You inspired me to sublingual some of mine and it seems to be coming on pretty heavy this way B-).


What oven temp did you use?
